Description
● CWDM MUX/DEMUX:
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 Multiservice Transport Device (Such as EDFA, DCM, OEO and so on), which can improve the manageability and interconnectivity of WDM Network.
● Features:
● Low insertion loss
● Based on thin-film filter technology
● Multiplexing of up to 16/8 channels on fiber pair/single fiber
● Standard CWDM band 1470nm - 1610nm, 20nm spacing
● Compliant to ITU-T G.694.2 standard and Telcordia GR1209, GR1221
● LC/SC/FC/ST, UPC/APC Interface are available
● Rate transparent for applications up to 10Gbps
● Monitor/Upgrade/1310nm Express port for external functions
● Completely passive, no electric power required
● Low-profile modular LGX box design optional, fits in LGX chassis
● Application:
Applications in CWDM Network
