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.

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.

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: Mates Patchcords With Different Connector Types Connectors With Different Ferrule Sizes Supported Minimizes Losses Between Fibers With Different Core Sizes And Numerical Apertures Male To Female (Hybrid) Connector Versions Rugged And Compact Design Low Insertion and Return Losses Applications: Patch Panel Interconnects; Fiber Distribution Hubs; Test And Measurement Stations; Optical Delivery Systems

300 - 2400 nm; low numerical aperture; Max Operating Temperature 85 °C; Core Diameter 50 µm; Coating Outside Diameter 250 µm Step Index multi mode fiber with pure fused silica core and fluorine doped silica cladding. With a low concentration of hydroxyl groups (OH), this fiber of the Anhydroguide™ series from Fiberguide Industries is suitable for wavelengths in the visible to infrared domain. It is primarily used in photonics applications where individual or bundled large core (> 50μm) multi mode fibers are needed for the transmission of optical energy.This “AFM” fiber features a low numerical aperture (0.12), resulting in a full acceptance angle of 14°. With a cladding diameter of 140 µm and a silicon buffer coating layer, the minimum bend radius recommended by the supplier is 13 mm (short term) or 25 mm (long term) respectively. The fibers are 100% proof tested using a 4-axis bend method with 100 KPSI. Typical applications are bio-analytical sensing, medical lasers, aerospace/defense, spectroscopy, nuclear plasma sensing or industrial laser systems.

Aluminium Coated, Single Mode, Multi Mode; 190 to 2400 nm; Core Diameter 50 to 400 µm; Mode Field Diameter 4.3, 9.0 µm; Cladding Diameter 125 to 440 µm; Numerical Aperture 0.12 to 0.275Fiberguide’s AFS-A/SFS-A/AGI-A/ASI-A/UVS-H2A series of aluminium coated fibers are designed for a wide temperature range (-269 to +400 °C) and superior strength (>100 kpsi). This allows for long life at extended stress levels in applications that require tight bends. Also, the strong chemical bond between the silica cladding and the aluminum enables direct termination without pistoning. This bond also makes aluminium coating the ideal choice to preserve deep UV performance in Fiberguide’s Solarguide UVS-H2A series of solarization resistant UV multi mode fiber. Within this series of aluminium coated high temperature fibers, users find step index (AFS/SFS, UVS-H2) and graded index (AGI) multi mode fibers as well as anhydrous silica (ASI) single mode fibers. As an option, some types of aluminium coated high temperature fibers can be provided with a broad selection of shaped tips – standard configurations as well as custom designed shapes. Shaped tip fibers provide optimum control over beam delivery and/or increased efficiency of light collection. Some of the fibers can also be end capped to achieve higher coupled power into a fiber core by reducing the power density at the air / silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber cores size, but can be easily customized for a variety of fiber types and specialized applications. Additionally, all fiber types 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.

This, combined with excellent corrosion resistance, and the fiber’s ability to be soldered or brazed, makes it the ideal fiber for many high temperature applications such as turbine flame monitoring, oil and gas down-hole sensing, and high vacuum or pressure applications.
