    Abstract: An optical device includes a first optical port connected to a first optical fiber, and a second optical port connected to a second optical fiber. The optical device further includes first optical components that switch first optical traffic carried via a first set of optical channels from the first optical port to the second optical port, and second optical components that switch second optical traffic carried via a second set of optical channels from the second optical port to the first optical port. The second set of optical channels includes different optical channels than the first set of optical channels. The optical device also includes a receiver that coherently detects portions of the first optical traffic and the second optical traffic, and converts the detected portions of the first and second optical traffic to electrical signals for delivery to a node or network external to the optical device.

    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.

    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.
