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.

Fused; Fiber Type DC (Nufern SM-9/105/125), MM (Nufern 105/125, 250), SM (SMF-28); 1250-1700 nm; Number of Legs 1x2, 2x2; SM IL ≤0.5-≤3.7 dB; Dimensions Ø2.9x50.8 mm Gooch & Housego’s (G&H) 18-X series of fused dual-clad fiber (FDCF) couplers and optical splitters offers a high coupling efficiency for multi mode (MM) fiber over a broad wavelength range with a low wavelength dependent loss. Light launched in the single mode core of the input single mode (SM) fiber or dual-clad (DC) fiber will transmit 100% through G&H’s 18-XXXXX-XX-XXXXX series FDCF coupler directly to the inner core of the output DC fiber, while light launched in the inner cladding of the DC fiber will couple to the multi mode (MM) fiber with at least 50% coupling efficiency depending on the core size of the MM fiber as a bigger MM fiber (i.e. 250 µm core) results in a higher coupling transmission percentage (70% or higher) to the MM fiber. As different DC fibers have different operating wavelength ranges, proper choice of SM fiber is very important for building a high-performance FDCF coupler. The typical 2x2 FDCF couplers have DC fiber in two opposite leads and MM fiber in the other two arms. The DC input fiber can be optionally replaced with a matching SM fiber and the MM output fiber can be terminated to form a 2x1 FDCF coupler. Key Features: Broad Wavelength Range: 1250 to 1700 nm 100% Transmission for single mode (SM) Fiber Input High Coupling Efficiency to Multi Mode (MM) Fiber Low Wavelength Dependent Loss Fiber Type: Double Clad (DC, Nufern SM-9/105/125 µm), Multi Mode (MM, Nufern 105/125 µm, Nufern 250 µm), Single Mode (SM, SMF-28) Number of Legs: 1x2, 2x2 Single Mode (SM) Insertion Loss (IL) for Port 1 -> Port 3 (Core): ≤0.5 dB Single Mode (SM) Insertion Loss (IL) for Port 1 -> Port 2 (Core): ≤2.5, ≤3.7 dB Dimensions: Ø2.9 x 50.8 mm Applications: Instrumentation; OCT Systems; Gyroscopes; Test and Measurement; Sensors

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.
