Product Description

Fiber Optic CWDM MUX DEMUX with 1550nm CATV port monitor

Coarse wavelength division multiplexer (CWDM Mux/Demux) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.

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 even 18-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 can also add "Skip Component" in a CWDM Mux/Demux module to reduce the IL as an option. Standard CWDM Mux/Demux package type include: Glass tube, stainless steel tube, ABS box package, LGX pakcage and 19" 1U rackmount.
