Section OAM

Traditional TDM services still remain. New services require much more bandwidth. Various services require many products, increasing network operator’s OPEX.

MS-OTN allows network operators to transport Any-rate client services with flexible adaptability. It integrates L0+L1+L2 technologies and provides universal switch (PKT, ODU, VC and λ) in one box. With intelligent protection, huge and flexible optical pipe, and end-to-end operation insurance, it will help network operators to provision faster services and applications, deliver better customer experiences than a traditional network as well.
