1x2 SC/UPC 1310/1490/1550 ABS Box Type Fiber Optic FBT Coupler
FBT Coupler Description
The single mode standard coupler features low excess loss, high stability and reliability. It 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 has the same coupling ratio on both 1310nm and 1550nm communication windows, and with low excess loss and low PDL. DWC are widely used for communication systems, fiber optic cable coupler CATV, and FTTH.
FBT Coupler Features
1. Low Excess loss
2. Low PDL
3. Environmentally stable
4. Good Thermal Stability
FBT Coupler Application
1. Long-haul Telecommunications
2. CATV Systems & Fiber Optic Sensors
3. Local Area Network
