Tunable DWDM optical modules enable dynamic wavelength switching across 96 C‑band channels via software commands. Unlike fixed‑wavelength designs,they reduce spare part types by over 95%,support remote wavelength scheduling,and enable colorless optical layer resource pooling. The module supports data rates from 9. 3 Gbps and is provided in an SFP+, MSA-compliant package. However, it possesses an additional feature that sets it apart—the capability to adjust the channel or color of the emitting laser. Recently, the use of wavelength division multiplexing (WDM) in mobile front-haul networks has attracted attention because of the advantages of wider bandwidth and reduced use of optical fiber. Our SFP+ tunable transceivers can operate on a wide range of wavelengths, and the specific wavelength.
