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: In some implementations, a device may transmit communication data to a transceiver via an access fiber optic cable. The device may determine that fiber sensing is to be performed for the access fiber optic cable. The device may cease transmission of the communication data for a predetermined time period. The device may generate an optical pulse after ceasing transmission of the communication data. The device may transmit the optical pulse to the transceiver via the access fiber optic cable. The device may receive, prior to expiration of the predetermined time period, a reflected signal from the access fiber optic cable based on the optical pulse. The device may analyze the reflected signal to generate sensing results. The device may perform one or more actions based on the sensing results.

Abstract: In some implementations, a device may obtain responsivity data for segments of a fiber optic cable. The device may receive, from a sensor device, vibration data associated with the fiber optic cable, the vibration data being produced by a vibration source in or on soil associated with the fiber optic cable. The device may normalize, based on the responsivity data, the vibration data. The device may determine, based on the normalized vibration data, a distance of the vibration source from the fiber optic cable. The device may perform one or more actions based on the distance satisfying a distance threshold.

Abstract: An optical node may include an optical switch and an optical add drop multiplexer (OADM). The optical switch may receive, via a space-division multiplexing (SDM) link that carries optical signals via multiple SDM elements, an optical signal to be switched from a first SDM element to a second SDM element. The multiple SDM elements may include multiple cores of a multi-core fiber, multiple modes of a multi-mode fiber, or multiple fibers of a fiber bundle. The optical switch may switch the optical signal from the first SDM element to the second SDM element. The OADM may add optical signals to an optical network or drop optical signals from the optical network via one or more SDM links that include the SDM link.

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.
