ETERN Optoelectronics's CCWDM (Compact CWDM) MUX/DEMUX is a multi-channel CWDM device with compact package designed for cost-effective multi-wavelength CWDM network applications. It is based on the Thin Film Filter (TFF) technology and and free-space technology platform. It operates at 20nm channel spacing ITU Grid CWDM wavelengths from 1270nm to 1610nm.
ETERN provides a series of customized CCWDM MUX/DEMUX devices packaged in metal box to meet different requirements on port configuration (1310nm, upgrade, and monitoring ports available), operating wavelength, fiber type, fiber length, input connector, and output connector.
