Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and, a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion.

Multiports having connection ports with securing features that cooperate with flexures and methods for making the same are disclosed. In one embodiment, a multiport comprises a shell, at least one connection port, at least one flexure and at least one securing feature. The at least one connection port comprises an optical connector opening and a connection port passageway, and the at least one flexure is associated with the at least one connection port. The at least one securing feature is associated with the at least one connection port, where the at least one securing feature cooperates with the at least one flexure.

An optical receptacle includes an optical receptacle main body and a cylindrical fixing member. The optical receptacle main body includes a first optical surface, a second optical surface, and an annular groove disposed to surround a first central axis of the first optical surface or disposed to surround a second central axis of the second optical surface. The fixing member is configured with a material with a smaller linear expansion coefficient than that of the optical receptacle main body, and is fit to the groove so as to be in contact with at least a part of an inner surface of the groove.

An OSFP optical transceiver having split multiple fiber optical port using reduced amount of MPO terminations is provided that includes two adjacent sockets integrated into the optical port of the OSFP optical transceiver. The two adjacent sockets are vertically oriented with respect to the mounting baseplate of the OSFP optical transceiver, and each of the two adjacent sockets is adapted to receive an MPO receptacle that terminates the proximal end of a bundle of fibers. The OSFP optical transceiver also includes an optical connection between each socket and a corresponding lens in the OSFP optical transceiver, for transmitting optical signals received from other transceivers into the OSFP optical transceiver and optical signals generated in the OSFP optical transceiver to other transceivers.

A multi-chip photonic assembly includes first and second photonic integrated circuits having first and second waveguides vertically stacked such that first vertical dimensions of the first and second waveguides occupy different horizontal planes in the stack. At least one of the first and second waveguides has a region that has a second vertical dimension that is larger than the first vertical dimension and either horizontally overlaps the other waveguide and/or vertically contacts the other waveguide. Light moving through one of the waveguides from the first vertical dimension to the other vertical dimension changes modes vertically so that the light moves from one waveguide to the other.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a multifiber ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and a rear portion of the housing comprises a keying portion and at least one locking feature integrally formed in the rear portion of the housing.

An optical module unlocking apparatus includes: a base, a sliding member, a driving piece, and an elastic piece. The sliding member is slidably disposed on the base along an insertion direction. The driving piece is rotatably connected to the base, the other end of the sliding member is connected to the driving piece, and the driving piece can rotate from a locked state to an unlocked state relative to the base under an action of external force, and drive the sliding member to move relative to the base along the insertion direction. A second connecting part is disposed on the driving piece. Because the driving piece is located outside a cage, space for disposing the elastic piece on the driving piece is sufficient, and the driving piece does not need to fit a spring plate. This simplifies a structure of the optical module and improves processing efficiency.

A receptacle for transceiver optical sub-assembly is configured for optical elements such as a light-emitting unit, a light guide unit, a light-receiving unit and a filter to connect thereto. The receptacle includes a lower receptacle body having a through bore, to which the light-emitting unit is connected; and an upper receptacle body having an axial receiving bore, to which the light guide unit is connected. The upper and the lower receptacle body are movable relative to each other in the x-y plane. The lower receptacle body can be moved relative to the upper receptacle body until an optical signal emitted from the light-emitting unit is optically coupled and collimated with an optical fiber in the light guide unit, and then the upper and lower receptacle bodies are fixedly connected together.

A satellite imaging system includes a camera with a pixel shifting mechanism, thermally stable imaging payload, and high-stability attitude determination and control system (ADCS) to improve image resolution. To address the overall stabilization requirement, the satellite incorporates a number of design elements that, in combination, provide the stable result required for good imaging.
