The Cisco Coarse Wavelength-Division Multiplexing (CWDM) Gigabit Interface Converter (GBIC)/Small Form-Factor Pluggable (SFP) solution allows enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fiber Channel services in their networks. The product set helps enable the flexible design of highly available, multi-service networks.The Cisco CWDM GBIC/SFP solution is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fiber Channel in campus, data-center, and metropolitan-area access networks.The Cisco CWDM GBIC/SFP solution has two main components: a set of eight different pluggable transceivers (Cisco CWDM GBICs and Cisco CWDM SFPs), and a set of different Cisco CWDM passive multiplexer/demultiplexer or optical add/drop multiplexers (OADMs). A Cisco CWDM chassis enables rack-mounting up to two of the Cisco CWDM passives. Both the transceivers and the passive multiplexers are compliant with the ITU-T G.694.2 standard defined CWDM grid.
