1471~1611+UG CWDM Mux Demux Module LC/APC Mini CWDM For Server CATV FTTH
CCWDM module of Gezhi is a wavelength division multiplexing technology based on TFF (thin film filter). It works in the same way as the CWDM module. The difference is that CCWDM adopts free space technology, Compared with the CWDM module, its package size is greatly reduced, and the insertion loss is lower and the consistency is better. It can replace CWDM products and be used in TC, enterprise network, PON network, CATV and other fields.
