Fiber Optic Combiners & Splitters

Fiber optic splitters ( also known as dividers) divide an incoming optical signal into multiple outputs, while fiber optic combiners (also known as multiplexers) merge multiple inputs into a single output. Fiber optic couplers can function as both splitters and combiners.
