Maine finishes fiber-optic telecom system

Telephone users in Maine are using a fiber-optic telecommunications system that automatically reroutes calls when part of a link is damaged.

Maine on Tuesday activated the final cog of the state's $100 million Bell Atlantic fiber-optic backbone, which carries millions of voice, data and video signals daily across the state.

The Synchronous Optical Network incorporates a "self-healing" architecture that instantly routes network disruptions in the reverse direction on the fiber-optic ring so that customers never experience the disturbance on their end.

"With the completion of this survivable backbone network, we've added a passing lane to the information superhighway in Maine, and we're eliminating the need for a breakdown lane," said Gov. Angus King.
