Fiber Optic Networks

ALSO CALLED: Fibre, Optical Networks, Fiber Optics, Fiber Optical Communication Networks, Fibre Optic Networks
DEFINITION: Resilient Packet Ring (RPR) is a network topology being developed as a new standard for fiber optic rings. The Institute of Electrical and Electronic Engineers (IEEE) began the RPR standards (IEEE 802.17) development project in December 2000 with the intention of creating a new Media Access Control layer for fiber optic rings. The IEEE working group is part of the IEEE's local area network (LAN)  …

Fiber optic rings are widely deployed as part of both MANs and wide area networks (WANs); however, these topologies are dependent on protocols that aren't optimized or scalable to meet the demands of packet-switched networks. The working group intends to actively promote RPR as a technology for the networking market as a whole, and as a technology to enable connectivity among various computing and telecommunications devices. The working group will specify an RPR access protocol and physical layer interfaces to enable high-speed data transmission in …
