ETERN Optoelectronics's DWDM (Dense Wavelength Division Multiplexing) MUX/DEMUX (Multiplexer/Demultiplexer) is a multi-channel DWDM device designed for ITU channel spacing applications. It is based on the Thin Film Filter (TFF) technology and operates at 100GHz or 200GHz or 50GHz channel spacing ITU Grid DWDM wavelengths from 1526nm to 1565nm.
ETERN Optoelectronics provides a series of customized DWDM MUX/DEMUX devices packaged in metal LGX box, or 19-inch 1U 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.
