  • Patent number: 11112564
    Abstract: A method of nonblocking optical switching includes guiding a first optical beam from a first input to a first output via a first path through an optical switching fabric. The first path traverses a phase shifter disposed between a pair of cascaded Mach-Zehnder interferometers. The method also includes receiving a second optical beam for a second path intersecting with the first path through the optical switching fabric. The method also includes moving the first optical beam from the first path to a third path connecting the first input to the first output without intersecting the second path. The method also includes shifting a phase of the first optical beam, with the phase shifter, while moving the first optical beam from the first path to the third path to prevent the first optical beam from interfering with the second optical beam.

  • Patent number: 11079556
    Abstract: A connector including two connector portions each including a ferrule and a latch, each latch including a distal end, and a proximal end, wherein the latch is pivotable about an intermediate connection portion; and a boot mounted to the connector portions, the boot movable longitudinally relative to the connector portions, wherein the boot causes the distal ends of the latch to pivot toward the ferrule of each connector portion as the boot is moved away from the connector portions. Front housings of the connector portions can each be rotated about the longitudinal axis of the ferrule without rotating the ferrule or the boot, to change the polarity of the two connector portions. The spacing between the two ferrules is adjustable. A holder holds the connector portions, the holder including side slots, the connector portions mounted to the holder by moving laterally to the side slots. The holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot.
