The FRM220 CWDM Mux/DeMux is modular design cards that support ITU-T G.694.2 wavelengths between 1271nm to 1611nmin 20nm increments. The FRM220 CWDM modules are protocol and rate transparent allowing different services such as 10GEthernet, 10GFC, STM-64, OC-192 to be transported across the same fiber link. The passive FRM220 CWDM Mux/De Muxmodules are available in 4 and 8-Channel (wavelength) models, supporting a variety of wavelength combinations and portconfigurations. The small and compact size of the CWDM modules yields one of the highest port densities in the industry. A 2Uhigh 19-module FRM220 chassis populated with modules can yield up to 120 channels of capacity. FRM220 CWDM modulesare passive devices that require no external power. They can also be installed in an FRM220 powered chassis with a NMCmanagement module¹ and can be managed using SmartView EMS network management software, third-party SNMP software,Telnet or a serial console port. The modules can be installed in any FRM220 chassis equipped with other FRM220 mediaconverters and transponders to provide a multi-service platform capable of delivering Ethernet, TDM, Voice and other servicesacross a CWDM fiber common link.
