Mini Size Wide Band Coupler (WBC)

 LightComm uses bandwidth expanding techniques (asymmetric techniques) to build the wide band coupler (WBC). The WBC has an operating bandwidth of ±40nm, low excess loss and PDL.

The mini size WBC is designed for the compact optical modules and communication systems.
