1×4 Single Mode Fiber Optic Fused Coupler/Splitter

SKU: FCSM

This FC Series fiber optic coupler provides us with monolithically integrated 1×4 function in a compact format. It features good uniformity, low excess loss, and very low polarization sensitivity. The device is ideal for splitting or combining light with exceptional performance over a wide wavelength range.
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. For beam-combining applications, search Combiner
