CWDM Mux / Demux 19inch Rack with 2 LGX Box of Dual Fiber with Upgrade Port
CWDM system utilizes advanced thin-film-filter technology designed for use with less expensive, non-temperature-controlled lasers of MUX/DEMUX, OADM and CWDM transceivers.The CWDM Mux/Demux covers all channels from 1270nm to 1610nm in 20nm increments. Aux/Demux can increase your network capacity combined with SOPTO Multiservice Transport Device (Such as EDFA, DCM, OEO and so on), which can improve the manageability and interconnectivity of WDM Network.
Features
