WDM-Wavelength Division Multiplexing, a technology which simultaneously transmits multiple optical channels (wavelength) through a single optical fiber. Three different kinds of wavelength coupling assembly are available for CATV systems, EDFA as well as Hi speed optical transmission systems.
Feature
Broad operating band
Low insertion loss
High isolation
High reliability and stability
