Abstract: A device may receive sensing data that is produced by an environment associated with a fiber optic cable. Based on the sensing data, the device may determine a sensing profile, which indicates a measure of vibration as a function of distance along the fiber optic cable and as a function of time. The device may receive new sensing data produced by the environment. The device may determine that the new sensing data satisfies a vibration deviation criteria, relative to the sensing profile, for a duration threshold. By satisfying the vibration deviation criteria for the duration threshold, the new sensing data may indicate that the environment includes an activity associated with an increased likelihood of damage to the fiber optic cable relative to the sensing data. The device may perform one or more actions based on the new sensing data satisfying the vibration deviation criteria for the duration threshold.

Abstract: An optical device includes a light source and diffuser, such as non-linear material, to form a supercontinuum of light energy of different wavelengths. An optical channel generator forms channels from the supercontinuum and forwards a multiplexed signal carrying the channels. The signal travels to an optical receiver through an optical fiber. The optical receiver identifies a non-linear penalty associated with forwarding the multiplexed signal on the optical fiber. The optical receiver modifies attributes of the received channels, such as increasing the magnitude of one of the channels, to cancel out the non-linear penalty.

Abstract: A first reconfigurable optical add/drop multiplexers (ROADM) and a second ROADM are connected by a primary light path and a protection light path. The first ROADM includes a first direction and a second direction, and the second ROADM includes a third direction and a fourth direction. The primary light path is coupled between the first direction and the third direction, and the protection light path is coupled between the second direction and the fourth direction. Transmissions on the primary light path are monitored, and when a problem is detected on the primary light path, the first and third directions are deactivated and the second and fourth directions are activated so that additional light signals are sent on the protection light path and not on the primary light path.

Abstract: A desired characteristic associated with a signal generated by a programmable transmitter is determined. The signal may be combined with other signals to form a combined signal, and sub-optical monitoring may be performed on the combined signal to determine an optical characteristic associated with the signal. The optical characteristic may be evaluated to determine if the programmable transmitter is operating improperly. For example, if the optical characteristic does not conform to a desired range of values, it is determined whether the optical characteristic is intentionally set outside of the desired range. A tuning instruction to reconfigure the programmable transmitter may be generated if the programmable transmitter is operating improperly.

Abstract: A network device may include a polarizing multiplexing transmitter, a polarization maintaining (PM) fiber, and a polarizing demultiplexing receiver. The polarizing multiplexing transmitter may generate an optical signal, split the optical signal into a first and a second split optical signal, and modulate the split optical signals based on electrical signals to form first and second modulated optical signals. The polarizing multiplexing transmitter may polarization multiplex the first and second modulated optical signals to form a polarization multiplexed signal and transmit the polarization multiplexed signal via the PM fiber to the polarizing demultiplexing receiver. The polarizing demultiplexing receiver may polarization demultiplex the polarization multiplexed signal to form the first and second modulated optical signals and directly detect the first and the second split optical signal from the first and second modulated optical signals. The polarizing demultiplexing receiver may convert the first and the second split optical signal to the electrical signals.
