Abstract

Asymmetric 4-port couplers and star couplers with 60 ports for multimode fibers are described. The power variations in the output fibers over a −40–+120°C temperature range are reported as is the insertion loss. The optimum output coupling required for minimum path attenuation is computed for a T-bus with symmetric and asymmetric couplers.
