Abstract: An optical module includes an optical source, a first polarization splitter-rotator, a second polarization splitter-rotator, a first port, a second port, a third port, and a fourth port. The optical source produces an optical signal. The first polarization splitter-rotator generates a first source optical signal based at least in part on the optical signal. The second polarization splitter-rotator generates a second source optical signal based at least in part on the optical signal. The first port transmits, to a first device, the first source optical signal and receives, from the first device, a first modulated optical signal. The first polarization splitter-rotator produces a second modulated optical signal. The second port transmits, to a second device, the second source optical signal and receives, from the second device, a third modulated optical signal. The second polarization splitter-rotator produces a fourth modulated optical signal.

Abstract: A system includes a cage and a first coil. The cage includes a first end and a second end opposite the first end. The first end is arranged to receive an electrical connector. The second end is arranged to receive a pluggable module such that the electrical connector forms an electrical connection with the pluggable module. The first coil is positioned on or in the cage such that the first coil is arranged to deliver electric power to the pluggable module by inducing an electric current in a second coil positioned in or on the pluggable module when the pluggable module is connected to the electrical connector in the cage.

Abstract: Aspects include a pluggable optical device and related optical system. The pluggable optical device comprises a housing, a printed circuit board (PCB) within the housing, and one or more blind mate optical connectors attached to the PCB along a first end of the PCB. The pluggable optical device further comprises one or more electrical contacts of the PCB near the first end, one or more external optical connectors arranged near a second end of the PCB opposite the first end, and one or more optical components attached to the PCB and included in optical paths extending between the one or more external optical connectors and the one or more blind mate optical connectors.

Abstract: A system includes a first device and a second device. The first device generates a source optical signal using a first optical signal and a polarization splitter-rotator. The second device modulates the source optical signal from the first device using a first data signal to produce a first modulated optical signal. The first modulated optical signal has a polarization that is orthogonal to a polarization of the source optical signal. The first device recovers the first data signal from the first modulated optical signal using at least the polarization splitter-rotator.

Abstract: An electrical connector for connecting to an array of surface contacts includes a connector body and a plurality of cable terminators. The connector body defines an interior volume and includes an external surface defining a plurality of cable openings each configured to receive a respective multi-conductor cable therethrough and a plurality of passageways. The plurality of cable terminators are each configured to couple with a respective multi-conductor cable exiting the second section of a respective passageway. Each cable terminator includes a plurality of pins each configured to couple with a respective conductor of the multi-conductor cable and to extend to a respective contact surface. The contact surfaces of the plurality of cable terminators extend to a second plane. The first plane and the second plane are coplanar when the array is in the connection position.
