SKU: PMFC
The NxM PM couplers/splitters are based on cascading 2×2 fused couplers in a star/tree configuration, featuring low optical loss, good uniformity, and high extinction ratio. In comparison with other approaches, this device has the best performance in industry for splitting or combining light over a wide wavelength and temperature range. Customer configuration is available.
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.
