Nortel Networks introduced a new CWDM version of its OPTera Metro 5000 solution designed for cable operators. The CWDM Enclosure increases network flexibility in delivering Gigabit Ethernet, storage connectivity, and other optical broadband services to customer premises. It could be deployed outdoors to aggregate multiple private CWDM optical channels from various customer premises over a single fiber pair. It could also be placed in basements of multi-tenant buildings to provide end customers with fully private, multi-protocol, optical wavelength services.
