Single Mode 1310/1550nm 1X2 Dual Window Coupler,CATV/FTTH fusion optical fiber splitter 1 in 2 out SC/LC/FC/ST connector
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.
