Abstract
A fault protection method for optical networks is provided. The method includes monitoring intensity of downstream optical signals transmitted through a first route from a rear terminal of a primary optical channel, so as to determine if there occurs any fault; and activating a second route to transmit optical signals when a fault in the primary optical channel is detected, in which the second route is counter to the first route. The present invention also includes a system performing the fault protection method.
