1x2 Singlemode Dual Window 1310/1550nm Fiber Optic Coupler
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
Various Coupling Ratio
Compact Size
High Stability and Reliability
Application
Long-haul Telecommunications
CATV Systems & Fiberoptic Sensors
Local Area Network
FTTH & LAN
