780nm 1X2 Polarization Maintaining Fiber Coupler

Idealphotonics’s 780nm fiber coupler can couple the optical signal transmitted in the optical fiber in the coupling area of the special structure, redistribute the optical power, and can be monitored in real time as needed. Fused taper splitters are widely used in fiber lasers, communication systems and OCT systems.

Product features：780 nm Polarization Maintaining Fiber Coupler、 Split ratios 50:50, 75:25, 90:10, or 99:1、 Bidirectional coupling (either end can be used as input)、 2.0 mm narrow key FC/PC or FC/APC connectors、 Individual test reports included with each coupler

Application area：Polarization Maintaining fiber amplifier 、 Fiber optic gyroscopes、 Fiber sensors
