When you purchase a CWDM optical transceiver, you may find out that there are many colors of transceiver bail. Are you confused? What is the use of so many different colors? Why are they designed in so many colors? This article will introduce the meaning of these colors and how to distinguish CWDM transceivers according to different colors.
What is CWDM Transceiver?
The CWDM optical transceiver is an optical module using the CWDM technology and is used to implement the connection between the existing network equipment such as the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical transceivers can increase network capacity by transmitting multiple data channels with individual optical wavelengths (1270 nm to 1610 nm) on the same single fiber.
CWDM Transceiver Color Code
Now that there are 18 channel wavelengths, in order to identify the different wavelengths, the industry defines the color code to avoid any confusion. See the color code as below.
The color code is very helpful for CWDM wavelength management and CWDM transceiver identify. OPTCORE offers a wide line of CWDM transceivers with high quality at low pricing, click to check the CWDM optics meet your needs
