With the continuous acceleration of the process of ALL IP, at present, regardless of the national backbone, provincial backbone or local network WDM system, OTN is the mainstream when selecting equipment in the initial stage of network construction. ![]() ![]() DWDM and OTN are two technical systems developed by wavelength division transmission technology in recent years: DWDM can be regarded as the previous PDH (point-to-point transmission), and the online and offline services are completed on ODF through hard jumpers OTN is like SDH (various types of Networking), with the function of cross-connection (whether it is the cross-connection of the electrical layer or the optical layer). ![]()
