The wavelength division multiplexer (WDM) is a device that multiplexes different optical signals into a beam which transmits along a single optical fibre. At the receiving end, demultiplexing is used to separate optical signals from different wavelengths. YOFC's WDM adopts the parallel fusion tapering method and has high isolation and high reliability.
