CWDM Module

Kwei fiber offers a full range of CWDM Mux-Demux and Optical Add Drop Multiplexer(OADM)units to suit all kinds applications and network solutions.Some most common ones are:Gigabit&10G Ethernet,SDH/SONET,ATM,ESCON,Fibre Channel,FTTx and CATV.
2.Our CWDM Mux Demux products provide up to 16-channel or even 18-channel Multiplexing on a single fiber.Due the 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:ABS box package,LGX pakcage and 19” 1U rackmount.
