At least one of the lock portion and the mating lock portion has an intersecting surface which intersects with both the front-rear direction and a perpendicular direction. Under the mated state, the abutment portion is positioned forward beyond the receiving portion in the front-rear direction and is brought into abutment against the receiving portion by a rearward force so that a rearward movement of the abutment portion beyond the receiving portion is regulated by the receiving portion.

Disclosed in the present invention is a connector assembly, including a guide shielding cover; a side cover plate; and a light guide piece. The guide shielding cover has a top wall and a side wall, and the side wall has an opening. The side cover plate is assembled on the side wall and shields the opening, and the side cover plate has a first mounting portion. The light guide piece has a second mounting portion matched with and assembled on the first mounting portion. The connector assembly in the present invention, through the side cover plate assembled on the side wall of the guide shielding cover, not only shields the opening on the side wall to generate an action of electromagnetic interference shield (EMI shielding), but also provides an additional construction for assembling the light guide piece through the side cover plate.

An object is, in a pluggable optical module, to compactly house an optical fiber used for connecting optical components in a housing in which a plurality of optical components are mounted. The pluggable optical module (100) includes: a plurality of optical components, a printed circuit board (51); one or more optical fibers; and optical fiber housing means (14). All or a part of the plurality of optical components are mounted on the printed circuit board (51). One or more optical fibers connect between the plurality of optical components. The optical fiber housing means (14) includes a guide that is disposed on a plate-like member and can wind the one or more optical fibers, and mounted to be stacked with the printed circuit board (51) on which the optical components are mounted and all or a part of optical components other than the optical components mounted on the printed circuit board (51).

An optical fiber mounting mechanism includes an optical fiber, a signal circuit, and a mounting structure. The optical fiber extends along a first direction. The signal circuit extends along the first direction. The mounting structure is disposed at ends of the optical fiber and the signal circuit. The mounting structure surrounds the optical fiber and the signal circuit. The mounting structure has an installation portion. The installation portion extends radially relative to the first direction as the axis direction. The installation portion has a plurality of elements. The elements are exposed from a surface of the installation portion. The surface has a normal direction parallel with the first direction.

An interconnect system includes a first circuit board, first and second connectors connected to the first circuit board, and a transceiver including an optical engine and arranged to receive and transmit electrical and optical signals through a cable, to convert optical signals received from the cable into electrical signals, and to convert electrical signals received from the first connector into optical signals to be transmitted through the cable. The transceiver is arranged to mate with the first and second connectors so that at least some converted electrical signals are transmitted to the first connector and so that at least some electrical signals received from the cable are transmitted to the second connector.

An edge-attachable (EA) optical connector includes an optical connector housing for an optical connector. The optical connector housing includes a slot that aligns with a module board edge finger electrical connector, such that the optical connector housing can be slid over a module board edge finger electrical connector and attached to the module board edge. An optical connector on one end of an optical fiber bundle or ribbon fits within the optical connector housing. When the optical connector housing is attached to the module board edge, the optical connector blind mates with a host optical connector supported by a bracket to which a host electrical connector is attached. An optical connector on another end of the optical fiber bundle or ribbon mates with a module board optical connector. The module board optical connector may include an optical socket mounted on an opto-electronic chip disposed on the module board. The EA optical connector can be easily attached to the module board edge such that it fits around the host electrical connector to allow for optical connectivity in addition to electrical connectivity.
