Protection Schemes for Metropolitan Optical Networks

Tags:
optical networking

Overview This paper outlines two different protection schemes designed for optical networks: Optical Unidirectional Path Switched Rings (O-UPSR), also called Optical Dedicated Protection Rings, and Optical Bidirectional Line Switched Rings (O-BLSR), also called Optical Shared Protection Rings. These two protection schemes have different effects on critical network functionality, such as wavelength utilization and total system capacity, and service providers must make informed decisions about which scheme is best suited to the specific needs of their networks. Outlined in this paper are the different technical operations and requirements of each scheme, as well as their benefits.
