Couplers, Splitters & Combiners

1x2/2x2 Dual Polarization Maintaining (PM) Fiber Optic Couplers/Splitters

This FC Series PM fiber optic coupler works on both orthogonally polarized light, providing a polarization-independent coupling function. 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.
