    Abstract: Wavelength multiplexed optical communication systems include a channeled chromatic dispersion compensator coupled to receive modulated optical beams associated with a plurality of optical channels at respective communication wavelengths. The channeled chromatic dispersion compensator applies independently selected dispersion compensations to each of the optical channels by identifying a dispersion compensation associated with a preferred bit error rate, inter-symbol interference, or other signal quality metric, or determined using optical fiber properties such as dispersion slope and zero dispersion wavelength. Chromatic dispersion compensation can be coupled with channel power equalization, and can be performed at a receiver or a transmitter or in the middle of a fiber span.

    Abstract: A plug may be coupled with a cable and include a fiber ferrule extending from the plug. A biasing mechanism may be arranged to bias a cover toward a covered configuration in which the fiber ferrule is situated within an internal volume defined by the cover and away from an uncovered configuration in which the fiber ferrule is situated at least partially outside of the internal volume defined by the cover. Bristles or other blockers may be positioned along or within a boundary of the internal volume of the cover, may be arranged to block particulate entry through the blockers into the internal volume of the cover in the covered configuration, and may be movable to permit passage of the fiber ferrule through the blockers in response to movement of the cover between the covered configuration and uncovered configuration.

    Abstract: Communication systems include network nodes that distribute an electrical or optical base signal to remote nodes for modulation at the remotes nodes. A first waveguide is coupled to transmit data to a corresponding remote node, a second waveguide is coupled to receive remotely modulated data from the remote node, and a third waveguide is coupled to deliver the base signal to the remote node. Typically, the base signal is an optical signal from a laser diode, and optical fibers communicate modulated data signals and the base signal. A portion of the base signal can also be modulated for communication with remote nodes.

    Abstract: A rack within a datacenter or other environment can include a plurality of appliances arranged in the rack such that ports of the appliances are aligned vertically or in another direction. A cartridge can include an elongate rigid body along which connectors are arranged. The connectors may be engageable with the aligned ports of the appliances in response to translation of the cartridge toward the rack. The cartridge can include cabling within the elongate rigid body, and the cabling can provide paths among subsets of the connectors, for example, such that subsets of the appliances are accordingly connected for transmission of data or other signals.

    Abstract: A cage assembly may define a part of a computing appliance. The assembly can include a cage formed by walls and defining a continuous interior volume bounded by a top face, a bottom face, a right face, a left face, a front face, and a rear face. A first edge connector may be within a leftward portion of the interior volume. A second edge connector may be within a rightward portion of the interior volume and positioned laterally from the first edge connector. The arrangement may permit engagement with multiple individual-width plugs (e.g., each bearing an individual paddle card) or a single plug (e.g., bearing multiple paddle cards spaced laterally from one another and aligned for engagement with the first and second edge connectors within the cage).
