Four-fiber ring completed
Sprint Corp., Kansas City, MO, and NEC America Inc., Herndon, VA, have completed a 16-node, 5100 mile, four-fiber bidirectional line-switched ring. It is carrying live traffic to Sprint`s customers in 11 states in the Southwest. NEC offers optical carrier, level 3, and OC-12 optical tributaries in an OC-48, four-fiber bidirectional line-switched ring. This ring allows Sprint to migrate the network to synchronous optical network OC-12, instead of digital signal, level 3, thus reducing the equipment needed to support a higher bandwidth.
