Abstract: A polarization multiplexed receiver includes a polarization separator and optical mixing, detecting and analog-to-digital components. The polarization separator receives polarization multiplexed optical signals containing a first data stream and a second data stream, and operate upon the polarization multiplexed optical signals to separate, in an optical domain, the first data stream and the second data stream to generate a first optical output having the first data stream and a second optical output having the second data stream. The optical mixing, detecting and analog-to-digital converting components receive the first and second optical outputs from the polarization separator, extract, in a digital domain, the first data stream from the first optical output of the polarization separator, and extract, in the digital domain, the second data stream from the second optical output of the polarization separator.

Abstract: A device may receive, from a sensor device, cable distance data identifying cable distances along the fiber cable to vibrations experienced by the fiber cable from a vibration device. The device may receive location data identifying geographic coordinates associated with the vibrations, and may correlate the cable distance data and the location data to generate correlated data. The device may receive, from the sensor device, data identifying a cable distance along the fiber cable to an alarm condition associated with the fiber cable, and may determine geographic coordinates associated with the alarm condition based on the correlated data and the data identifying the cable distance along the fiber cable to the alarm condition. The device may perform actions based on the geographic coordinates associated with the alarm condition.

Abstract: In some implementations, a system may receive a cable map for a deployed cable. The system may receive vibration data indicating a vibration associated with a first section of the cable. The system may determine a characteristic associated with the first section of the cable based on the vibration. The system may determine a location associated with the characteristic based on the cable map. The system may determine that the first section of the cable is associated with the location based on the location being associated with the characteristic. The system may associate the location and a length of a second section of the cable extending from an initial location to the location. The system may receive an input identifying the length of the second section of the cable and may output the location based on associating the location and the length of the second section of the cable.

Abstract: A device may provide, to a user device, a first message instructing a technician to move fiber cables and may receive a first signal based on the technician moving the fiber cables and a rest signal based on the technician stopping movement of the fiber cables. The device may calculate a distance, an average peak signal, and a baseline signal based on the first signal and the rest signal and may calculate a data collection window based on the distance, the average peak signal, and the baseline signal. The device may provide, to the user device, a second message instructing the technician to move one fiber cable at a time and may receive second signals based on the technician moving one fiber cable at a time. The device may provide, for display to the user device, the data collection window and indications of the second signals.

Abstract: A system includes an optical transmitter and an optical receiver. The optical transmitter includes a first comb light source, a second comb light source, an optical switch configured to selectively switch either the first comb light source or the second comb light source through to an output of the optical switch, and optical modulators configured to apply differential phase modulation, to channels associated with the switched first comb light source or with the second comb light source, to generate modulated light output signals. The optical receiver includes coherent receivers configured to receive the modulated light output signals from the optical transmitter, and detect and process the received, modulated light output signals to generate corresponding digital signals. The optical receiver further includes a digital signal processor configured to apply forward error correction to the digital signals to generate forward error corrected digital signals.
