Couplers, Splitters & Combiners

Fiber Optic WDM Coupler/Splitter 980/1550 nm

The FC Series 980/1550 nm WDM is based on Our advanced fused biconical taper technology and compact packaging structure. It features low insertion loss, high isolation, flat passband, high reliability, and stability. The device is ideal for 980 pump and 1550 nm signal wavelength division multiplexing in fiber optic amplifier systems. Couplers are highly efficient in splitting light with little loss, about 0.2dB per joint, but incur significant losses when combining lights; for example, a 50/50 coupler produces a 50% loss to each beam when combined.
