The F-CPL-S22155 single wavelength optical fiber couplers allow bi-directional coupling and can be used to either split or combine signals. This 2 x 2 coupler with a 50/50 ratio provides optimal performance at a center wavelength of 1550 nm in package type B. Bare fiber ends are standard. Use the model number F-CPL-2x2-OPT and coupler option code when ordering non-standard fiber connectorization. The F-CPL-S22155 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 FP3-FH1 bare fiber holder and 818-FA2 bare fiber mount. Newport’s wide range of Optical Fiber Coupler products have been developed using fused fiber technology.
