GPON OLT Module (GPON Class C++)

This article will show you how to identify the wavelength of a CWDM optical module by the color of the pull ring. We all know that CWDM has a total of 12 wavelengths, the full range of which is between 1270-1610nm, and the interval of each wavelength is 20nm. The waveband of the rear wave is 1470-1610nm, and the rear waveband is generally used for ultra-long-distance transmission.

For conventional optical modules, we can easily judge the wavelength of the optical module from the color of the pull tab. For example, the black pull tab indicates 850nm, and the blue pull tab indicates 1310nm. So for the SFP CWDM optical module, what wavelengths does the color of the pull ring correspond to? Please see the table below.

Front wave (SFP CWDM special band):

Through the above table, I believe that everyone can clearly identify the wavelengths represented by the colors of the SFP CWDM optical modules. Knowing the wavelength represented by the color of the pull ring helps us to identify the module with the corresponding wavelength. The above is the product knowledge related to the SFP CWDM optical module introduced to you. If you want to know more about the optical module knowledge, you can read the previous articles.
