The new generation of OTN (Optical Transport Network) technology is developed on the basis of the original transport network. OTN is based on WDM technology and introduces the powerful operation, maintenance, management and assignment (OA) capabilities of SDH on the basis of super-large transmission capacity. At the same time, it makes up for the deficiency of SDH's function and maintenance management overhead when facing the transport layer. OTN inherits the dual advantages of SDH and WDM, and can avoid the emergence of a series of problems in traditional systems. At present, OTN has become the most widely used data transmission service technology for broadband customers.
