Fault detection improves network protection

摘要

Fiber cuts cause a significant number of disruptions and outages. As businesses and consumers become increasingly intolerant of network failures, downtime can be very expensive to carriers due to both lost revenue and tarnished images. Economic forces have put carriers in the difficult position of simultaneously reducing costs while improving overall network reliability. As a result, carriers continually search for better ways to protect networks against such fiber faults and reduce costs by more efficient use of protection bandwidth.
