1x4 FBT fused 1310/1550nm Dual Window Coupler Splitter ABS module SC/UPC/APC For CATV Optical Signal Distribution
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.

Specification
Low excess loss
Low PDL
Dual operating window
High stability and reliability
Applications
