Singlemode 2x2 Fiber Optic Coupler - Dual Window Coupler
Gracyfiber offers a wide range of narrowband and wideband singlemode 2x2 fiber optic couplers. It has a bandwidth of ±40 nm, coupling ratios of 50:50, 90:10, and 99:1, and can be customized by volume. Additionally, these couplers are bi-directional, allowing either port to be used as an input port, and contain SMF-28e+ fiber optics with a Ø900 µm jacket. These couplers are available with FC/PC or FC/APC connectors, or without connectors.
