The FRM220-CWMD Mux/DeMux are modular design cards that support ITU-T G.694.2 wavelengths between 1271nm to 1611nm in20nm increments. The FRM220-CWMD modules are protocol and rate transparent allowing different services such as 10G Ethernet,10GFC, STM-64, OC-192 to be transported across the same fiber link. The passive FRM220-CWMD Mux/DeMux modules are availablein 4,8 and 16-Channel (wavelength) models, supporting a variety of wavelength combinations and port configurations. The small andcompact size of the CWDM modules yields one of the highest port densities in the industry. A 2U high 19-module FRM220 chassispopulated with modules can yield up to 120 channels of capacity. FRM220-CWMD modules are passive deviceas that require noexternal power. They can also be installed in an FRM220 powered chassis with a NMC management module¹ and can be managedusing SmartView EMS device management software, third-party SNMP software, Telnet or a serial console port. The modules can beinstalled in any FRM220 chassis equipped with other FRM220 media converters and transponders to provide a multi-service platformcapable of delivering Ethernet, TDM, Voice and other services across a CWDM fiber common link.
