10:90 2000nm 1X2 single mode fiber coupler

10:90 2000nm 1X2 single mode fiber coupler

NIR-FBC-W1922 MIR 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

Product features：Fused fiber couplers for 1900-2400nm、 50:50, 75:25, 90:10 or 99:1 coupling ratios、 Each broadband coupler comes with its own test report

Part Number：--

Application area：Visible light communication、 Power monitoring、 Optical splitting、 Test instrumentationFiber optic sensor
