A method, optical module, and optical amplifier are configured to detect fiber discontinuities at or near a port from which high powered optical signals are input into a fiber span. These fiber discontinuities can include fiber pinches, and are detected by monitoring for slight changes in a backscatter signal. Detection is quick and efficient based on the backscatter signal being attenuated by the fiber discontinuities twice, namely once as the high powered optical signals and again as the associated backscatter signal of the high powered optical signals returning to the port. Various remedial actions can be taken upon detecting fiber pinches at or near the port. |
