Mini Size Dual Window Coupler (DWC)
Dual window coupler (DWC) is built by asymmetric coupling technique. The operating bandwidth of this coupler is expanding to ±40nm. The DWC coupler has the same coupling ratio on both 1310nm and 1550nm communication windows. The mini size DWC is designed for the compact optical modules and communication systems.
