1550/1590 nm Filter-Based Wavelength Division Multiplexers     


The 1550/1590 nm Filter-Based Wavelength Division Multiplexers are high-performance optical components designed for multiplexing and demultiplexing C-band and L-band signals in fiber-optic communication systems. Based on thin-film interference filter technology, they offer low insertion loss, high channel isolation, low polarization-dependent loss, and excellent temperature stability. Featuring a compact, reliable design with an epoxy-free optical path, they provide efficient wavelength management for dual-band EDFA systems and high-capacity optical networks.
