25:75 2000nm 2x2 single mode Fiber Coupler

MP-FBC-W2000 series single-mode fiber coupler is a coupler for mid-infrared band splitting developed and produced by our single-mode fiber fused taper machine IPCS-5000-SMT. It has excellent performance and can cover the entire communication band (1900-2220nm). At the same time, we can provide customers with more cost-effective narrow-band couplers with a central wavelength of 1950nm, 2004nm, 2050nm, and 2327nm with a bandwidth of ±20 nm. The maximum power of our coupler with connector or bare fiber is 500 mW. We have 50:50, 75:25, 90:10 or 99:1 coupling ratio couplers for customers. Our 2x2 couplers are based on the fused taper process, so they are bidirectional, and any port can be used as the input
