OTDS is a 4-channel 2.5G service access card launched by Sintai Communication Co., Ltd.; its main function is to finish the 3R regeneration of any 4-channel signals under any protocol within the rate of 42Mbit/s~2.67Gbit/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 low-cost wavelength division transmission solution for any access of services with a rate of 2.5G or below.
