Abstract:
Systems and methods are disclosed, including an optical switching system comprising an upstream optical signal detector between a first node and a second node configured to detect optical signals from the second node and to switch data traffic from a working path to a protecting path when optical signals from the second node are indicative of a failure in the working path; wherein the first node is configured to transmit data traffic in first optical signals with wavelengths in channels in a first band and receive the data traffic in second optical signals with wavelengths in channels in a second band from the second node; and one or more optical filter, between the second node and the upstream optical signal detector, configured to block signals with wavelengths in the first band that are reflected because of a break in the path between the optical filter and the second node.

Claim (Index 20):
A system, comprising:\n a working path in an optical transmission system, wherein the working path carries bidirectional data traffic in the optical transmission system when there is no failure in the working path; a protecting path in the optical transmission system, wherein the protecting path carries the data traffic in the optical transmission system when there is a failure in the working path; a tailend node in the optical transmission system designed to receive data traffic in first optical signals with wavelengths in channels in a first band and transmit data traffic in second optical signals with wavelengths in channels in a second band; and a headend node in the optical transmission system configured to transmit data traffic in the first optical signals with wavelengths in channels in the first band and receive the data traffic in the second optical signals with wavelengths in channels in the second band, the headend node comprising: an upstream optical signal detector positioned between the headend node and the tailend node and configured to detect optical signals from the tailend node and to implement a switch of data traffic from the working path to the protecting path if signals from the tailend node are indicative of a failure in the working path by being one or more of (1) below a predetermined level of power and (1) not detected; and one or more optical filter between the upstream optical signal detector and the tailend node, the optical filter blocking signals with wavelengths in channels in the first band from the headend node that are reflected from a break in the working path between the optical filter and the tailend node.
