摘要： A network device may include a receiver to receive optical pulses from an optical path, wherein the optical pulses include a plurality of intensities and represent data. The network device may also include a processor to determine a rate of bit errors introduced during propagation of the optical pulses through the optical path and to determine a parameter indicative of nonlinear effects of the optical path based on the rate of bit errors and the plurality of intensities.

摘要： A system and methods include generating an optical time domain reflectrometry signal; transmitting the optical time domain reflectrometry signal on a first fiber path in a first direction through at least one optical amplifier; receiving a reflection of the optical time domain reflectrometry signal on the first fiber path in a second direction opposite the first direction; transmitting the reflected optical time domain reflectrometry signal on a second fiber path in the second direction, where the second fiber path is not the first fiber path; and determining a location of a fault on the first fiber path based on the reflected optical time domain reflectrometry signal.
