Fused Fiber WDM Coupler
Pictures and Schematic Diagram
Overview of the Fused Fiber WDM Coupler
The fused fiber coupler for WDM system is used to combine several signals into one fiber or split the single fiber input into multiple outputs. It can be used to double the fiber transmission capacity or enable the bi-directional communication using one single fiber. Typical applications for our fused fiber WDM coupler are in fiber-optic network upgrade, expansion or construction of new integrated optical network services such as radio and television, telecommunications, internet triple play PON EOC, etc.
