Fused Optical Coupler 
Optical coupler is an optical device that combines or splits power from optical fibers.

Fiber optic splitters take an optical signal and supply two outputs. They can further be described as either Y-couplers or T-couplers.

• Y-couplers have equal power distribution, meaning that the two output signal each receive half of the transmitted power.
• T-couplers have an uneven power distribution. The signal outputs still carrier the same signal, however the power of one output is greater than the second output.
