CWDM SFP Transceiver Module is a hot-swappable input/output device that plugs into an SFP port or slot of switch or router, linking the port with the fiber-optic network. The Coarse Wavelength-Division Multiplexing (CWDM) 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, multiservice networks.

Our CWDM SFP transceiver module provides a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fiber Channel in campus, data-center, and metropolitan-area access networks.
