Description
Coarsewavelength division multiplexer (CWDM Mux/Demux) utilizes thin film coatingtechnology and proprietary design of non-flux metal bonding micro opticspackaging. It provides low insertion loss, high channel isolation, wide passband, low temperature sensitivity and epoxy free optical path.
Qoptronics CWDMproducts include: bare single CWDM device packed in glass tube or stainlesssteel tube, CWDM Mux Demux modules packed in ABS box up to 16-channel or even18-channel Multiplexing on a single fiber or CWDM modules packed in standard 19”1U rackmount. Due to the low insertion loss is needed in WDM networks, we canalso add “Skip Component” in a CWDM Mux/Demux module to reduce the IL as anoption. Standard CWDM Mux/Demux package type include: Glass tube, stainlesssteel tube, ABS box package, LGX pakcage and 19” 1U rackmount.
