25G OTU service card launched by Shenzhen JHA Technology Co. ,Ltd. supports four types of service access with 16 to 32G rates. Its main function is to finish the 3R regeneration of any 4-channel signals under any protocol within the rate of 25 Gbit/s to be accessed, and then convert them to optical signals of a standard DWDM wavelength or standard CWDM wavelength, so that the multiplexing unit can conduct WDM for optical signals of different wavelengths and also achieve the inverse process of the above process. It’s applicable to the wavelength division transmission solution for 25G rate services, and compatible with 16G or 32G FC.
