SC/APC 1310/1490/1550 0.9mm 1M Fiber Optic FBT Coupler
FBT Coupler Description
FBT Optical Fiber Couplers are used to distribute optical signals to two output fibers. We offer various types of single mode or multimode coupler including standard couplers, polarization independent couplers, wavelength independent couplers and wavelength flattened couplers. These couplers are highly stable. They have low insertion loss, low polarization sensitivity and excellent uniformity.
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
