Abstract: A bit error generating device includes a light source, an input device, and a control processor. The control processor includes logic configured to: receive protocol or bitrate information regarding a live traffic signal via the input device; determine bit error simulation signal parameters based on the received protocol or bitrate information; configure the light source to generate the bit error simulation signal based on the bit error simulation signal parameters; and instruct the light source to inject the bit error simulation signal into an optical fiber carrying the live traffic signal.

Abstract: A system includes a wavelength tunable laser to provide a first optical pulse of a first wavelength and a second optical pulse of a second wavelength to an optical fiber, a reflection detector to determine a first fiber attenuation curve from the first reflected pulse and a second fiber attenuation curve from the second reflected pulse, and a discontinuous loss event analyzer to identify a discontinuous loss event at a discontinuous loss point in at least one of the first fiber attenuation curve and the second first fiber attenuation curve, determine a return loss slope based on a return loss at the discontinuous loss point for the first fiber attenuation curve and a return loss at the discontinuous loss point for the second first fiber attenuation curve, and determine whether the discontinuous loss event is a bad fiber bending event based on the return loss slope.
