Product Series Overview
1x2 and 2x2 Singlemode Fiber CouplersThe F-CPL-B22355-FCUPC Broadband Coupler is operational over both the 1310 and 1550 nm windows. This 2x2 coupler has a 50/50 (3 dB) coupling ratio. It has FC/UPC connectors. The F-CPL-B22355-FCUPC can be used directly with the 918D-IS-1 fiber optic detector. It can also be used with the 818 or 918D series detectors with the associated FP4-FC FC connector fiber adaptor and 818-FA connectorized fiber mount. See the Related Products tab for more information.
50/50 Fiber Optic Couplers
50/50 fiber optic couplers are used to evenly split fiber optic light. A 2x2 coupler combines the light on one side and evenly splits it on the other side. A 1x2 coupler works in the same way, but one of the input fibers has been cut short. We offer broadband, narrowband and wavelength flattened versions.
FC/UPC, FC/APC or Bare Fiber Pigtails
All standard models come with non-terminated (pigtailed) ends. FC/UPC or FC/APC fiber connectors are also available for most models.
Rugged Housing and Cabling
A semi-ruggedized housing, used on 1x2 and 2x2 couplers at 633, 780, and 850 nm, consists of a stainless steel outer housing from which 1 m long, 900 µm buffered fibers exit through molded strain relief boots. All other couplers feature a fully ruggedized black plastic housing with 1 m long, 3 mm PVC covered pigtails.
Fused Biconical Taper Construction
A fused coupler consists of two, parallel optical fibers that have been twisted, stretched and fused together so that their cores are very close to each other. This forms a coupling region with the length determining the coupling ratio from one fiber to the other. During the manufacturing process, light is launched into an input port and the output power from each output port is carefully monitored. When the desired coupling ratio is achieved, the fully automated manufacturing process is stopped. The resulting coupler is essentially one fiber with two cores that are very near to one another. This process is known as the Fused Biconical Taper (FBT) process.
Broadband Fiber Optic Couplers
Our Broadband couplers optimized to work over both the 1310 and 1550 nm windows. This allows users the versatility to use a single device at both wavelengths.
