Low Excess Loss 1x2 50:50 Coupling Ratio Single Mode 1310nm And 1550nm Dual Window Fiber Optic Coupler (DWC)

1x2 Single Mode 1310nm and 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 excess

loss Low PDL

High stability and reliability

Application
CATV
Optical communication systems
Testing instruments
