Wide Band Coupler (WBC)

xunquan uses unique bandwidth expanding techniques (asymmetric techniques) to build the wide band coupler (WBC). The WBC has an operating bandwidth of ± 40nm or EDFA C band or L band, and it features low excess loss and low wavelength depend loss (WDL).

Key Features
§  Low excess loss
§  Low PDL
§ High stability and reliability

Applications
§  CATV
§  LAN
§  Optical fiber sensors
§  Testing instruments
