Features: With the increasing competition in domestic and international telecom operation markets, the construction of metropolitan area networks (MANs), especially metropolitan area transport networks, has gradually become a key focus in the industry. Currently, a series of new metropolitan optical transport technologies have emerged, including: multi-service transport platforms based on SDH, metropolitan DWDM and OADM, CWDM, elastic packet ring (RPR), and metropolitan optical Ethernet. These next-generation metropolitan optical transport technologies, with different development backgrounds, networking and service-bearing capabilities, and network application environments, are gradually adapting to various types of metropolitan network application demands and the needs of operators for network construction, maintenance, and management. They have already begun to show their respective competitive advantages in practical network applications. This book provides an introduction to the principles and characteristics of the aforementioned next-generation metropolitan optical transport technologies, including: new
