Abstract:
An optical end terminal in which protection switching is implemented by using (i) the optical data receiver thereof for detecting a path failure and (ii) the optical data transmitter thereof for signaling the detected path failure to the protection-switching circuit. In an example embodiment, the optical data receiver is configured to detect a path failure based on the presence of certain data-recovery errors. The optical data transmitter is operatively connected to the optical data receiver and configured to generate an in-band dither tone of a predetermined frequency in response to such failure detection. The protection-switching circuit is configured to (i) detect dither tones in the optical signals passing therethrough and (ii) connect the optical data receiver to the protection path instead of the working path in response to detecting the dither tone of the predetermined frequency.

Claim (Index 18):
An apparatus comprising:\n an optical data receiver connected to receive, by way of an optical switch, an optical input signal modulated with first data, the optical switch being configured to selectively connect the optical data receiver to a first optical input fiber port or to a second optical input fiber port; an optical data transmitter configured to generate an optical output signal modulated with second data to carry a first dither tone in response to being signaled by the optical data receiver of a path failure; and an electronic controller configured to generate a control signal in response to the first dither tone being detected in the optical output signal; and wherein the optical switch is configured to change an optical input fiber port through which the optical data receiver receives the optical input signal in response to the control signal.
