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.

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless SteelFiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11.Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.

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.
