With the rapid development of business and a strong drive to achieve OTN technology and its growing maturity, OTN technology has been applied to local test or business network. Foreign operators on OTN transmission network interface has the ability to support the obvious demand, and the practical application of these networks are the main types of ROADM equipment, mainly with the network management and network maintenance costs and other factors closely related to the scale.
OTN technology in the current all-optical network's key technology was not against the backdrop of existing optical technology based on a compromise put forward Transport Network networking technology. In order to solve the customer's digital signals to monitor the issue, light-channel optical channel layer is divided into modules and optical transmission channel data of the two sub-units, similar to the above-SDH technology and access layer. As a result, from the very nature of technology, OTN technologies for WDM and SDH has been the traditional advantages of a more effective combination of inheritance and at the same time to expand the business with the needs of the transmission network functions, from the type of equipment Point of view, OTN and WDM equipment, the equivalent of SDH equipment for the integration of a device at the same time expanding the original equipment of the type of function advantages.
OTN technology as a new optical transport network technology, and expanding the succession of the transmission network has many advantages characteristics, is the broadband customer data for business-driven technology transfer one of the best. OTN technology and equipment has been basically mature and can be applied to the major metro and core trunk transmission level. In addition, the existing SDH network gradually does not mean that the SDH network the disappearance of the original features, OTN network will better support these functions, while NG-OTN further discussion would not impede existing OTN technology.
