CWDM SFP Transceiver: How Much Do You Know About It?

You may have seen SFP modules which are with colorful markings, such as color arrow on label and color coded bale clasp. And most of them are named CWDM SFP or DWDM SFP transceivers. But do you know why they are designed as various colors? Here will give the answer by introducing CWDM SFP transceivers in details.

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 SFP Transceivers With Different Wavelengths

In general, CWDM SFPs come in eight wavelengths that range from 1470 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.
