OZ Optics

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.

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.

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).

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. Key Features: Rugged and Compact Size Wide Wavelength Range Single Mode, Multi Mode and Polarization Maintaining Fiber Versions Low PDL and Wavelength Dependency High Power Handling Wide Attenuation Range Low Backreflection Designed to Meet Telcordia Requirements Applications: Optical Power Equalization and Power Control for WDMs and Multi-channel Optically Amplified Networks; Telecommunications; CATV; LAN; Test and Measurement; Receiver Padding; Optical Sensors

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.

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.

Reflective Style, Manually (Screw) Controlled; Fiber Type SM, MM, PM; 400 to 1625 nm; Connector Type NTT-FC/PC, ST, SC, LC/PC, other; Attenuation up to 40, 60 dB 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.

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.
