OTN is a transmission network organized at the optical layer based on wavelength division multiplexing technology, which can integrate the advantages of traditional SDH/SONET and WDM technologies to effectively protect the network. It is widely used in metropolitan area networks, and reasonable network structure and topology settings are required to meet the needs of numerous users. Based on this, OTN technology can demonstrate its own advantages on the basis of optical and electrical domains processing, improve the shortcomings of SONET/SDH, provide large-capacity transmission channels for IP networks, and support service granularity. The advanced technology embodied in OTN equipment greatly improves the level of network scalability, stability and availability, providing end-to-end wavelength/sub-wavelength connections that are completely transparent, speeding up network operation, providing telecom-grade protection capabilities, and allowing for management and monitoring of various network layers.
In network maintenance, OTN equipment technology can provide large-grain business transmission to meet the growing demand for bandwidth. Many users have increased their use of OTN equipment to improve network performance, which can be applied to metropolitan area networks and create a unified way of transmitting data information. In fact, OTN technology can provide GE, 10G, and 40G rate large-grain business support for IP metropolitan area networks, which is the basis for the operation of large-scale networks. Under the influence of OTN technology's large carrying capacity, the core layer and convergence layer of metropolitan area networks will improve their protocol protection capabilities, effectively meeting the needs of scheduling, aggregation and protection recovery. In response to the current rapidly changing network environment, it is very necessary to apply OTN technology, which fully demonstrates the feasibility of OTN technology.
By analyzing the operational requirements of metropolitan area networks, the direction of mobile network business development has been clarified, and OTN technology has been fully applied to metropolitan area networks to set up IP networks based on the network nodes of metropolitan area networks, and construct the structure of the new mesh networks in metropolitan area networks. Applying OTN technology to metropolitan area networks will become the main research direction in the future, realizing the rapid development of OTN technology. With the rapid development of science and technology, network technology is constantly evolving. OTN device technology will be widely used in metropolitan area networks.
Through the above analysis, the excellent performance of OTN technology is clear. In modern metropolitan area networks, OTN technology is needed to set up IP networks reasonably, and by improving network carrying capacity, more network usage needs can be met. Technical personnel should monitor the operation of metropolitan area networks in a timely and effective manner, identify network allocation issues at the first time, use OTN technology to design the core layer of the network reasonably. Only in this way can network equipment be better compatible, and the application effects of OTN device technology in metropolitan area networks can be improved.
