Product Description
Dawnergy's FBT fiber couplers are fused fiber branching devices that split optical signals for monitoring and feedback applications. These precision components are extensively used in fiber amplifier power control systems and transmission equipment for performance monitoring and feedback control.
Key Features
- Compact design for space-constrained installations
- Low insertion loss for minimal signal degradation
- Low polarization dependent loss (PDL)
- High stability and reliability in demanding environments
Primary Applications
- EDFA (Erbium-Doped Fiber Amplifier) systems
- CATV (Cable Television) distribution networks
- Passive optical networks
- FTTH (Fiber to the Home) and LAN installations
