1310nm 1550nm Dual Window Coupler Single Mode FBT Coupler 1x2 Fused Biconic

1✖️2 Fused Biconic Coupler, SingleMode 1310nm 1550nm Dual-Window 0.9mm Loose Tube

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

Dual operating window

High stability and reliability

Applications:

Optical communication systems

CATV

FTTH
