Cisco 1000BASE-CWDM GBIC, 1550 nm 1250Mbit/s 1550nm network media converter

Cisco 1000BASE-CWDM GBIC, 1550 nm, Yellow 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 Fibre Channel services in their networks. The product set helps enable the flexible design of highly available, multiservice networks.
The Cisco CWDM GBIC/SFP solution is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre 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.

Cisco CWDM GBICs
The Cisco CWDM GBIC is a hot-swappable input/output device that plugs into an 802.3z standards-compliant GBIC port or slot of a Cisco switch or router, linking the port with the fiber-optic network.

Platform Support
The Cisco CWDM GBICs are supported across a variety of Cisco switches, routers, and optical transport devices. For more details, refer to the document Cisco CWDM GBIC Compatibility Matrix.
