1x2 SC/APC Triple Window Mini Type 1M Fiber Optic FBT Coupler
FBT Coupler Description
1×N Fused Bi-conical Tapered (FBT) splitter is the series connection of N-1 pieces of 1×2 splitter.
These devices are used extensively in fiber amplifier power control. They are also utilized in transmission equipment for performance monitoring and feedback control.
Our Single Mode Fiber Optic Splitters are highly stable for multi-port optical signal splitting with low insertion loss. All devices are qualified according to industry standard test procedures, and available in a wide range of split ratios, lengths, and packaging. Custom terminations are also available.
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
