Regular price $0.00

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.
