25:25:25:25 1X4 Full Band Fused Taper Single Mode Fiber Coupler Module 1310-1550nm

The single-mode fiber coupler is a coupler for near-infrared band splitting developed and produced based on our single-mode fiber fused taper machine IPCS-5000-SMT. It has excellent performance and can cover the entire communication band (1260-1620nm). At the same time, we can provide customers with more cost-effective narrow-band couplers with a central wavelength of 1310nm, 1392nm, 1480nm, 1512nm, 1550nm, 1650nm, 1742nm with a bandwidth of ± 20nm. The Max. power of our coupler with connector or bare fiber is 500mW. 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 all work in both directions, and any port can be used as the input end.

Product features：Fused Fiber Coupler for 1260-1620nm、 50:50, 75:25, 90:10 or 99:1 coupling ratios、 Bidirectional coupling (either end can be used as input)、 2.0 mm narrow key FC/PC or FC/APC connectors、 Each broadband coupler comes with its own test report

Application area：Visible light communication、 Power Monitoring、 Optical splitting、 Test Equipment
