(P)FPD Fiber to Photodiode Couplers
Pigtail/Receptacle Versions; Fiber Type SM, MM or PM; Tilt Adjustment Feature for Many Couplers; Pigtail Versions Optional with Pre-configured Connectors
(P)FPD fiber to photodiode couplers are available for virtually any photodiode on the market, using either SM, MM or PM fiber. The coupler design is both rugged and flexible, allowing customers to do their own alignment if desired. For OEM applications, miniature pigtail style fiber to photodiode couplers are available that do not use the tilt adjustment technique. These feature both a smaller size and lower cost.Our fiber to photodiode couplers come in three basic designs. The most common design consists of two baseplates (one holding the photodiode and the other one containing the focusing optics and the connector for the input fiber), separated by a resilient O-ring. OZ Optics’ patented tilt adjustment technique is used to achieve the maximum coupling efficiency (typical >80% for SM fibers, depending on fiber and photodiode characteristics) even for very small spot sizes of <10 µm.
For the second design, the fiber, lens and photodiode are glued into a single assembly without the tilt adjustment technique. The third and final design uses no lens at all. The fiber is simply butted against the photodiode. Both of these designs are intended for OEM applications. For optimum coupling efficiency, stability, and minimum backreflection, we recommend using pigtail style fiber to photodiode couplers, available with a wide variety of fiber types and cable sizes, also preterminated with different types of connectors. Receptacle style versions are typically only available for multimode applications, or large active area photodiodes.
AMS Technologies welcomes opportunities to fiber couple into your specific photodiode. Please contact us with details of the fiber required and the photodiode specifications, and we will determine the best, most cost effective method of fiber coupling.

(R)ND-11 Fixed Attenuators
Pigtail Style, Optional Removable Filter; Fiber Type SM, PM, MM; 440 to 1625 nm; Connector Type NTT-FC/PC, ST, SC, LC, MU, other; Attenuation 5 to 30 dB
OZ Optics’ (R)ND-11 series of expanded beam style neutral density fixed attenuators are ideal for multi mode applications and for applications where attenuating fibers are not available or usable. These pigtail-style attenuators provide mode independent fixed attenuation when used with multi mode fibers. The insertion loss will not depend on how the light is launched into the fiber. This is a significant advantage over other attenuator designs.
The attenuators consist of a set of collimating and focusing optics and a central baseplate containing the filter. The expanded beam design permits higher power handling than plug style attenuators. The filters themselves can be either permanent (ND-11 series) or removable (RND-11 series). This provides great flexibility for experimentation.

AA Fiber Adapters
Universal Adapters; Connector Type (Super, Ultra) NTT-FC/PC, SMA 905/906, AT&T-ST, (Angled) SC, Universal; Fiber Type Single Mode (Hybrid Patchcord, Lens Style), Multi Mode (Lens Style)
OZ Optics’ AA series of universal connectors and hybrid patchcords are designed for mating two patchcords that have different connectors on their ends. Butt joint style universal connectors feature different female receptacles on either side. Patchcords are simply plugged into either side, and the fiber ends butt together in the middle. These connectors offer an inexpensive and reliable way to connect matching single mode, multi mode, or polarization maintaining patchcords with differing fiber terminations.
Connectors with a universal ferrule adaptor design are also available, for connectors that have 2.5 mm diameter ferrules, or 1.25 mm diameter ferrules. These receptacles are best suited for temporary measurements and give added flexibility. Hybrid patchcords have a female receptacle on one side and a male connector on the other side. A small length of fiber lies within the device to transmit the light. Male-to-male hybrid patchcords are also available.
Lens style universal connectors are ideal for connecting fibers that have different optical characteristics. They consist of an input receptacle, a collimating lens, a focusing lens and the output receptacle. Light from the input fiber is first collimated, then focused back into the output fiber. The alignment is precisely controlled using OZ Optics’ patented alignment technique. Lens style universal connectors are tilt adjustable to compensate for any offsets between the fiber cores and the connector housings.
Please note that universal connectors will not couple light efficiently from a multi mode fiber into a single mode fiber. High losses are unavoidable in this situation, since multi mode fibers have both larger numerical apertures and larger core sizes.
Key Features:

BARE Fiber Adapters
Bare Fiber Adapters; Magnetic and Spring Clamp Versions; Connector Type FC, SMA905, ST, SC, LC, E2000; Ferrule Hole Size 80 to 250 µm; Reusable and Easy to Clean
OZ Optics’ BARE series of bare fiber adapters provide a simple and effective way to use unterminated fibers with commercial receptacles. Simply strip, clean and cleave your fiber and insert into the bare fiber adapter. The BARE series adapters are recommended for power meter connections, temporary system repairs or wherever a quick fiber connection is required.
OZ Optics has recently improved the bare fiber adapter design to now use a magnetic clamping mechanism. The new design gently yet firmly holds the fiber in place without harming soft acrylate coatings and is even easier for operators to use. The magnetic clamp applies no stress to the fiber, which makes it ideal for PM fiber related measurements including extinction ratio (ER), polarization dependent loss (PDL) and polarization mode dispersion (PMD).
Bare fiber adapters with spring clamp accommodate up to 900 µm OD jacketed fiber. Bare fiber adapters with magnetic clamp accommodate 250 to 400 µm OD jacketed fiber. 900 µm OD tight buffer and custom jacket sizes are available. (Please contact AMS Technologies).

BB-100/400/500/700-11 Variable Optical Attenuators
Blocking, Pigtail Style; Fiber Type SM, MM, PM; 350 to 2050 nm; Connector Type NTT-FC/PC, ST, SC, LC/PC, other; Attenuation up to 80 dB
OZ Optics’ BB-100/400/500/700-11 series of compact PC board mountable blocking pigtail style variable attenuators with low backreflection are designed to meet Telcordia standards. These attenuators can be used for 1300 nm and 1550 nm as well as for C, L and S bands, with minimal changes in the insertion loss. Mounting holes provide easy attachment to PC boards and patch panels. The mounting hole patterns and attenuator sizes can be modified to meet customer requirements
The attenuators consist of two collimating lenses, prealigned for optimum coupling efficiency. A threaded radial screw is used to block the collimated beam between the two lenses. Because the attenuator works by directly blocking the beam, it is polarization insensitive. A seal cap is used to seal the junction against temperature and humidity effects. The attenuator can even withstand immersion in water for extended periods of time. Variable attenuators are offered with single mode, multi mode, or polarization maintaining fibers.

BB-200 Variable Optical Attenuators
Blocking, Receptacle Style; Fiber Type SM, MM, PM; 350 to 2050 nm; Connector Type (Receptacle) NTT-FC/PC, ST, SMA 905, SC; Attenuation 2 dB to 80 dB
OZ Optics’ BB-200 series of blocking receptacle style variable attenuators consist of two baseplates with lenses. The two baseplates are aligned for optimum coupling efficiency using a patented alignment technique. A threaded radial screw is used to block the collimated beam between the two lenses. Rotating the screw changes its position within the collimated beam, thus varying the power level coupled into the receiver fiber. Because the attenuator works by directly blocking the beam, it is polarization insensitive.
Because of limitations in receptacle tolerances, receptacle style attenuators are not recommended for single mode or polarization maintaining applications requiring low losses and good repeatability. Instead, please refer to the OZ Optics BB-100/400/500/700-11 series of blocking pigtail style variable attenuators.

BB-500-11-ND Variable Optical Attenuators
Neutral Density Filter, Pigtail Style; Fiber Type SM, MM, PM; 800 to 1625 nm; Connector Type NTT-FC/PC, ST, SC, LC/PC, other; Attenuation IL to 40 dB
OZ Optics’ BB-500-11-ND series of compact PC board mountable, pigtail style variable attenuators are designed to meet Telcordia requirements. These attenuators with low backreflection can be used for 1300 nm and 1550 nm, as well as for C, L and S bands, with minimal changes in the insertion loss. Mounting holes provide easy attachment to PC boards and patch panels. The mounting hole patterns and attenuator sizes can be modified to meet customer requirements.The attenuators consist of two baseplates, each baseplate containing a fiber followed by a collimating lens.
The attenuator is prealigned for optimum coupling efficiency using a patented tilt alignment technique. A variable neutral density filter is used to provide more uniform attenuation in multi mode applications than the blocking screw technique. The attenuation is controlled by a turn screw on the side of the attenuator, which controls the position of the filter.
Variable attenuators based on the neutral density filter are ideal for multi mode fiber applications where one may be concerned about modal noise. When blocking style attenuators are used with multi mode fiber, some modes are blocked, while others are transmitted. This can produce 1 dB or greater modal noise fluctuations with coherent sources. A variable attenuator using a neutral density filter is not as strongly affected by modal noise. However, neutral density filter attenuators offer lower attenuation range (around 40dB) and can only handle about 50mW of power. While generally used for multi mode applications, OZ Optics can also produce single mode and polarization maintaining versions.

OZ Optics’ BB-600-11 series of compact PC board mountable, reflective style, variable attenuators with low backreflection can be used for C, L and S wavelength bands, with minimal changes in insertion loss. Reflector style housings are ideal for applications where the input and output fibers must be attached to the same side of the attenuator. Mounting holes provide easy attachment to PC boards and patch panels.
The BB-600-11 series of reflector style attenuators contain either a variable neutral density filter or a blocking plate depending on the attenuator version selected. The blocking style is ideal for high power (over 50 mW) applications, while the neutral density filter provides more uniform attenuation in multi mode applications. The attenuation is controlled by a turn screw on the side of the attenuator, which controls the position of the filter or plate.

Beamsplitters & Combiners
PM or SM Splitters/Combiners; 1550 nm, Other; Splitting Ratio 50/50-90/10; PDL ±0.25 dB; Directivity >50 dB
OZ Optics’ fiber optic beamsplitters are used to divide light from one fiber into two or more fibers. Light from an input fiber is first collimated, then sent through a beam-splitting optic to divide it into two. The resultant output beams are then focused back into the output fibers. Both 1xN and 2xN splitters can be constructed in this fashion with as many as eight or more outputs, with both low return losses and low insertion losses.
Standard parts available in this series are FOBS-12P (1x2) and FOBS-22P (2x2) pigtail-style splitters, FOBS-12 (1x2) and FOBS-22 (2x2) receptacle-style splitters, as well as LDBS-12P (pigtail-style) and LDBS-1 (receptacle-style) laser diode to fiber splitters, and finally ULBS-12P (pigtail-style) and ULBS-1 (receptacle-style) laser to fiber splitters
This design is extremely flexible, allowing to use different fiber types on different ports, and different beamsplitter optics inside. Custom designs combining circulators, polarizing splitters and non-polarizing splitters in the same package are routinely manufactured. Splitters can be made with either fibers permanently attached to each port (pigtail style) or with receptacles on each port that one can plug your fiber into (receptacle style). OZ Optics can also build source to fiber couplers with built-in beamsplitters for either laser or laser diode sources. Contact AMS Technologies for details.
If size is a concern, we recommend that you consider OZ Optics’ miniature line of splitters.
Within OZ Optics’ series of beamsplitters and combiners, the two most common types of splitters offered are polarizing beamsplitters and polarization maintaining (PM) beamsplitters. Polarizing beamsplitters split incoming light into two orthogonal states. They can also be used to combine the light from two fibers into a single output fiber. When used as a beam combiner, each input signal will transmit along a different output polarization axis.
PM splitters use a partially reflecting mirror to transmit a portion of the light from the input fiber to the main output fiber and reflect the remainder of the light to the second output fiber. All ports made using polarization maintaining fiber are aligned so that polarized light aligned parallel to the stress rods on the input fiber emerges from the output fibers in the same manner, maintaining the polarization state to a high degree. Splitters that only split off a small portion of the input light are commonly known as taps and often used for power monitoring applications. For a very cost-effective alternative configuration, combining the functions of a tap and monitor photodiode in a single unit, we invite you to review OZ Optics’ OPM series of inline optical taps and monitors.

BHEPS-1000 Bright Polarization-Entangled Photon Source Broadband Telecom
Signal/Idler Degeneracy Wavelength 1550 ±0.7² nm; Photon Pairs Bandwith FWHM 3 nm @ -3 dB Spectral Brightness; Noise Suppression >75 dB; Fidelity >98%
OZ Optics' advanced entangled photon sources harness the high optical confinement within a periodically poled nonlinear waveguide (PPNW) to achieve exceptional efficiency and produce plentiful photon pairs. Utilizing spontaneous parametric down-conversion (SPDC) within a periodically poled lithium niobate (PPLN) type-2 waveguide, situated within a fiber-based Sagnac loop, photons are generated. The thermal stabilization of the PPNW ensures maintenance of the ideal phase matching condition. Following the creation of photon pairs, pump photons and associated fluorescence noise are efficiently filtered out from the remaining pairs using a built-in set of optical filters.
This remarkable stability is attained through the self-compensation effect of an all-in-fiber Sagnac interferometer, complemented by a single-frequency external cavity laser operating at 775 nm with an ultra-narrow linewidth. Consequently, bright, high-performance, and low-noise entangled photon sources operating at room temperature are realized. The resulting polarization-entangled photon pairs are generated within a narrow spectral bandwidth of just a few nanometers in the C Band, with a center wavelength of 1550 nm.
Key features:
Highest counts/coincidence rate available in the market
High Heralding efficiency and excellent fidelity
Turn-key, highly stable, room temperature operation
Rugged, alignment free, proprietary design

Signal/Idler Degeneracy Wavelength 1550 ±0.6² nm; Photon Pairs Bandwith FWHM 80 nm @ -3 dB Spectral Brightness; Noise Suppression >75 dB; Fidelity >98%
OZ Optics' advanced entangled photon sources leverage the high optical confinement within a periodically poled nonlinear waveguide (PPNW) to achieve remarkable efficiency and a rich abundance of photon pairs. These photons are produced through spontaneous parametric down-conversion (SPDC) within a periodically poled lithium niobate (PPLN) type-2 waveguide, nestled within a fiber-based Sagnac loop. Ensuring optimal phase matching, the PPNW is thermally stabilized. Upon photon pair creation, any residual pump photons and associated fluorescence noise are meticulously filtered out by an integrated set of optical filters.
Exceptional stability is realized through the self-compensation effect of an all-in-fiber Sagnac interferometer, complemented by a single-frequency external cavity laser operating at 775 nm with an ultra-narrow linewidth. Consequently, these entangled photon sources deliver bright, high-performance outputs with minimal noise, operating comfortably at room temperature. The resulting polarization-entangled photon pairs exhibit a narrow spectral bandwidth of just a few nanometers in the C Band, centered at 1550 nm.

BM Backreflection Meters
Single and Dual Source; 633-1625 nm; Reflectance Dynamic Range -1--70 dB; Fiber Type SM, MM; 8° Angled NTT-FC/APC Receptacle
OZ Optics’ BM series of backreflection meters measure the total accumulated optical return loss that is reflected back through a device or fiber under test. The measured reflections are caused by Rayleigh scattering, sudden changes in the refractive index within the device under test (DUT), or from connector ends. BM series meters are available as portable handheld devices (BM-100 and BM-200) or in a benchtop form factor (BM-1000 and BM-2000). The BM series backreflection meters are configured with an FC/APC connector on the output port, to minimize unwanted reflections. The meters have either one or two built-in laser diodes (plus a choice of SLEDs or LEDs for benchtop models) for return loss measurement at specific wavelengths. An optional detector can be added to the unit for insertion loss measurements. Reference patchcords for calibration are available.
BM series meters cover a wide range of available wavelengths, thus providing measurement capabilities for non-telecom applications as well as telecom. BM-100/200 portable meters' wavelengths range from 8050 nm to 1625 nm, while the BM-1000/2000 benchtop meters are offered with special wavelengths, ranging from 633 nm to 1625 nm.
The BM-1000/2000 benchtop backreflection meters feature a colour touchscreen display with a simple graphical user interface. The units come with a built-in memory that allows the user to store measured DUT test results.
The BM series backreflection meters can be operated remotely via the built-in USB interface. A universal AC/DC power supply is included with all units. Reference patch cords for calibration are available. Adapter patch cords are also available, to allow the meter to be used with devices having different connectors.

BTF-100 Motor Driven Variable Bandwidth Tunable Filters
Polarization Insensitive; 1100 to 1650 nm; Bandwidth 1 to 18 nm; Insertion Loss 3 dB; PDL <0.3 dB; Fiber Type SM, PM; Connector Type FC/PC, ST, SC, LC, MU, None
OZ Optics’ BTF-100 series of motorized adjustable variable bandwidth tunable filters are pigtailed components with built-in control electronics that allow both the wavelength and bandwidth of the filter to be controlled through an electrical interface. The device contains two independently variable tunable bandpass filters in series. With the two filters tuned to cover slightly different wavelength ranges, the overall passband becomes the region where the two individual passbands overlap. The amount of overlap determines the width of the filter. Since each filter can be tuned over a range of wavelengths, both the center frequency and width of the passband can be controlled. Each individual filter consists of a multi-layer thin film bandpass filter, designed to give a flat top pass band, with steep roll-off shapes. The center wavelength of the filters is adjusted by changing the angle of incidence of the light as it impinges upon the filter. In the BTF-100 series of motor driven variable bandwidth tunable filter, each filter is independently rotated relative to the incoming light, in order to change the passband. OZ Optics uses a special technique to minimize polarization dependencies, allowing PDL effects to be kept below 0.3 dB, and making the spectral response virtually polarization independent. This feature makes the BTF-100 series ideal for today’s DWDM system applications. Variable bandwidth tunable filters using single mode (SM) and polarization maintaining (PM) fibers are offered. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patch cords. However, OZ Optics can construct devices using other PM fiber structures. OZ Optics also carries some alternative fiber types in stock, please contact AMS Technologies for availability. If necessary, OZ Optics is willing to use customer supplied fibers to build devices. In addition to the BTF-100 series of motor driven variable bandwidth tunable filters, OZ Optics provides four further series of tunable filters – BTF-11 series of manually adjustable variable bandwidth tunable filters, TF-100 series of digital tunable filters, TF-100-11 series of motor driven tunable filters, and finally TF-11 series of manually adjustable polarization insensitive tunable filters.

CPS/BCPS-1000 Correlated Photon Pair Sources
Signal/Idler Degeneracy Wavelenght 1550 or 810 nm; Photon Pairs Bandwidth FWHM ~80 or ~3 nm; Noise Suppression 75 dB; Max. Output Power of Pump Laser 12 mW, variable.
The correlated photon pair sources generate photon pairs entangled in time or energy through spontaneous parametric down conversion (SPDC). Once the photon pairs are created, the pump photons are filtered out from the remaining pairs using an integrated set of optical filters.
Equipped with a stabilized pump laser and internal variable optical attenuator for pump power control, OZ Optics' correlated pair sources ensure stable operation. The SPDC medium is thermally stabilized to maintain optimal phase matching conditions, thereby maximizing photon conversion efficiency.
The photon pairs are separated using either a wavelength splitter (WDM) or polarizing beam splitter (PBS), depending on the spectral bandwidth of the unit ordered.
Key features:
Rugged, alignment free and all-in-fiber design
High heralding efficiency
Turn-key, highly-stable and room-temperature operation

Hand-held Device; Fiber Type SM, MM, PM (PANDA); 350 to 2050 nm; Connector Type NTT-FC/PC, ST, SC, other; Attenuation IL to 40, 60 dB
OZ Optics’ DA-100 series of compact, hand-held and rugged digital attenuators feature high resolution, high speed, high attenuation range and high power handling (blocking technique only). These CE approved attenuators have low insertion loss, low backreflection, low PDL and flat wavelength response. The DA-100 series of hand-held digital attenuators can be calibrated for up to four wavelengths, for C or L bands. Alternatively, the units can be calibrated for a continuous range. By using interpolation between the calibration wavelengths, the units are capable of providing accurate attenuation levels over a continuous, broad range of wavelengths. A computer interface allows users to access or remotely control the units through a PC. An optional, built-in rechargeable battery is available for field use, where AC power may not be readily accessible.
OZ Optics provides digital attenuators that use either single mode, multi mode or polarization maintaining (PM) fiber. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patchcords. However, OZ Optics can construct devices using other PM fiber structures. OZ Optics does carry some alternative fiber types in stock, so please contact AMS Technology for availability. If necessary, OZ Optics is willing to use customer supplied fibers to build devices.

DD Variable Optical Attenuators
Electronically Controlled; Fiber Type SM, MM, PM (PANDA); 350 to 2050 nm; Connector Type NTT-FC/PC, ST, SC, other; Attenuation IL to 40, 60 dB
OZ Optics DD series of compact PC board mountable motor driven variable attenuators with low backreflection offers excellent speed, repeatability, and accuracy. Single mode and polarization maintaining (PM) attenuators utilize a novel blocking style attenuation technique, while multimode attenuators use a variable neutral density filter to minimize mode dependent losses. Both types feature a homing sensor to calibrate the attenuator, removing the need to use external taps, and a jam-proof tuning mechanism.The PC version uses a reliable stepper motor that can be controlled by an external driver. The basic model allows direct access to the stepper motor, as well as a logic level output for HOME position information. The -DR option adds a high-speed driver circuit that accepts four logic level inputs to control the stepper motor. Finally, the -MC option features an embedded microcontroller with a programmed calibration curve. The units are addressable and support RS232, SPI, or I²C communication protocols.AMS Technologies and OZ Optics can also customize the design to fit your needs. There are smaller and faster versions if lower resolution is acceptable. Contact AMS Technologies for detailed specifications.

DDL-650-11 Differential Polarization Delay Lines
Varies Delay Between Polarization States; Delay Range ±50 ps; Delay Resolution 0.0027 ps; Return Loss -40, -50, -60 dB; Max. Insertion Loss 1.2 dB
OZ Optics’ DDL-650-11 differential polarization delay lines represent the next stage in controlling polarization mode dispersion in optical networks. The devices split the light within a fiber into orthogonal polarizations, and then actively vary the time that one polarization travels compared to the other polarization before combining the two polarizations together again.
With this technique, one can introduce up to ±50 ps of optical delay in a system. The resolution of the DDL-650-11 differential polarization delay lines is better than 0.003 ps, thus providing a high degree of control. The devices are easily controlled by a computer via an RS-232 interface. Home and end position sensors allow easy monitoring of the device status and prevent any potential damage to the device.

DR-100 Digital Variable Reflectors
980 to 1625 nm; Reflectance Range 2 to 60 dB; Fiber Type SM, MM, PM; PDL 0.05, 0.08 dB; Optical Max. Power Level Continuous 500 mW (MM), 50 mW (SM)
OZ Optics’ DR-100 series of digital variable reflectors enables the user to generate a known level of return loss to evaluate system response. The unit allows testing the return loss sensitivity of devices such as laser diodes, transmitters, isolators and so on. By generating a precise reflection level, system performance (bit error rate, noise levels, isolator performance) can be evaluated. A built-in calibration table accurately defines intermediate degrees of reflection from 2 dB to as high as 60 dB for different wavelengths. DR-100 digital variable reflectors are offered using either single mode (SM), multi mode (MM), or polarization maintaining (PM) fibers. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patch cords. However OZ Optics can construct devices using other PM fiber structures. OZ Optics also carries some alternative fiber types in stock, please contact AMS Technologies for availability. If necessary, OZ Optics is willing to use customer supplied fibers to build devices. For best results, the standard versions of the DR-100 series are designed to accept angled FC/PC connectors. Other connector types are possible with lower dynamic reflectance range. DR-100 digital variable reflectors can be controlled remotely via a USB interface. A universal AC/DC power supply is included with all units. The DR-100 digital variable reflectors can also be provided with a custom built-in fused coupler which directs a fraction of the reflected light to a second optical connector on the unit. The user can use this signal for monitoring the reflected power or determining the influence of reflected power on his device under test. For details, please contact AMS Technologies. Key Features:
