What’s CWDM SFP Transceiver?

CWDM SFP is a kind of optical transceiver which combines the CWDM technology. Similar with the traditional SFPs, CWDM SFP is also a hot-swappable input/output device that plugs into an SFP port or slot of a switch or router, and links the port with the fiber-optic network. It is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre Channel (FC) in campus, data-center, and metropolitan-area access networks.

CWDM SFPs usually with 16 wavelengths that range from 1270 nm to 1610nm. In order to better identify the wavelength to which the Gigabit Ethernet channel is mapped when using these CWDM SFPs, we use the color markings on the devices, such as color arrow on label and color coded bale clasp to achieve it. This is why there are many SFPs with different colors for applications. Here, we take Cisco for example. Here, we take Cisco for example. The following table lists the CWDM SFPs with their wavelength and color codes.
