Product Details
Mini Size Dual Window Coupler (DWC) 1310 and 1550nm for EDFA
compact optical modules
The mini size DWC is designed for the compact optical modules and
communication systems. 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.
