1x2 Single Mode FBT Fiber Coupler 1310/1550nm Dual window coupler (DWC) is built by asymmetric coupling technique. The operating bandwidth of this normal coupler is expanding to ±40nm, and the ultra broadband coupler is expanding to ±80nm. The DWC coupler has the same coupling ratio on both 1310nm and 1550nm communication windows, and with low excess loss and low PDL. DWC couplers are widely used for communication systems, CATV and FTTH.

Features
Low insertion loss
Low PDL
High channel isolation
Excellent environmental reliability
