1310nm 3X3 Single Mode Fiber Coupler

The NIR-FBC-W1216 NIR series single-mode fiber coupler is developed based on our single-mode fiber fusion tapering machine IPCS-5000-SMT. It is a high-performance coupler designed for splitting light in the near-infrared wavelength range, covering the entire communication band (1260-1620nm). We also offer high-cost-performance narrowband couplers with center wavelengths of 1310nm, 1392nm, 1480nm, 1512nm, 1550nm, 1650nm, and 1742nm, with a bandwidth of ±20nm. Our couplers, available with connectors or bare fiber, can handle a maximum power of 1W, and are manufactured using a one-time fusion tapering process. These couplers are reliable, compact in size, and ideal for fiber optic sensor applications.

Product features：Fusion fiber coupler, used for 1260-1620nm 、Coupling ratio of any desired coupling ratio 、Bidirectional coupling (either end can be used as the input end) 、2.0 mm narrow-key FC/PC or FC/APC connector 、Each broadband coupler comes with its own test report
