Optical Fiber Coupler, Broadband, 1 x 2, 10/90, 1310/1550 nm

The F-CPL-B12351 Broadband Coupler is operational over both the 1310 and 1550 nm windows. This 1x2 coupler has a 10/90 (10%) coupling ratio. It has bare fiber ends. Use the model number F-CPL-1x2-OPT and coupler option code when ordering non-standard fiber connectorization. The F-CPL-B12351 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. See the Related Products tab for more information.
