PRODUCT DESCRIPTION
CWDM products include: bare single CWDM device packed in glass tube or stainless steel tube, CWDM Mux Demux modules packed in ABS box up to 16-channel or 18-channel. Multiplexing on a single fiber or CWDM modules packed in standard 19" 1U rackmount. Due to the low insertion loss ,it's widely used in WDM networks, we can also add "Skip Component" in a CWDM Mux/Demux module to reduce the loss as an option. Standard CWDM Mux/Demux package type include: Glass tube, stainless steel tube, ABS box package, LGX pakcage and 19" 1U rackmount.
