Product Description
FBT Fiber Coupler
FBT Fiber Coupler is a kind of passive component that couple optical and realize the
distribution of light power. It can divide a light signal from an optical fiber into several
ones, realizing the separation or combination of light signal, or be used to extend the fiber
link. It belongs to optical passive components, can be applied to the telecom network ,
CATV network, subscriber loop system, regional network.
Features
- Low excess loss
- High Isolation
- Compact size
Applications
- Long-haul telecommunications
- CATV systems & Fiber sensors
- Local area network
