ETERN Optoelectronics's CWDM (Coarse Wavelength Division Multiplexing) MUX/DEMUX (Multiplexer/Demultiplexer) is a multi-channel CWDM device designed for cost-effective multi-wavelength CWDM transmission network applications. It is based on the Thin Film Filter (TFF) technology and operates at 20nm channel spacing ITU Grid CWDM wavelengths from 1270nm to 1610nm.
ETERN Optoelectronics provides a series of customized CWDM MUX/DEMUX devices packaged in metal LGX box, or rack mount to meet different requirements on port configuration (2 to 18 channels, 1310nm/upgrade/monitoring ports available), operating wavelength, package type, fiber type, fiber length, input connector, and output connector.
