The PCB is constructed as a rigid board. The laser emitter is electrically connected to the PCB. One end of the PCB is fixed on the heat sink, and the other end of the PCB is constructed as the electrical interface. The optical system transmits light emitted from the laser emitter to the optical interface.

A housing for an electronic device includes a panel, where the panel includes a window. A cage includes a plurality of panels and a first end and a second end that opposes the first end. The cage further includes an opening at its first end and an enclosure disposed between the panels of the cage. Connecting structure is disposed at the first end of the cage, where the connecting structure secures the first end of the cage to the panel. The cage is suitably dimensioned to receive and retain a portion of a pluggable module within the enclosure when the pluggable module is inserted within the opening at the first end of the cage.

The present disclosure provides a connector assembly including a receptacle connector, a shielding shell and a heat sink. The shielding shell covers the receptacle connector. The heat sink is assembled to the shielding shell and includes a heat dissipating base plate and a heat dissipating fin soldered on the heat dissipating base plate. The heat dissipating base plate has a soldering region on which solder is provided and a recessed channel provided between a rim of the heat dissipating base plate and an outer periphery of the soldering region. The solder is provided within the soldering region in a manner such that a face of the soldering region is covered by the solder.

Embodiments described herein may be related to apparatuses, processes, and techniques related to creating deep cavities within a substrate or at an edge of the substrate, by etching a cavity in the substrate to a first copper stop layer, removing the first copper stop layer, and then etching deeper into the cavity to a second copper stop layer. In embodiments this process may be repeated until the desired cavity depth is reached. Other embodiments may be described and/or claimed.

An incorrect insertion and removal prevention system that can prevent an operator from incorrectly selecting a port to be operated without sacrificing the port mounting density is described. An optical transmission device 100 of the incorrect insertion and removal prevention system includes a plurality of ports 101 for transmitting and receiving an external signal, a touch sensor 102 installed in each of the ports 101 to detect a contact of the human body, a control unit 110 for causing a display unit 130 to display information about the port 101 corresponding to the touch sensor 102 detecting the contact of the human body, a storage unit 120 for storing information for distinguishing each port 101, and the display unit 130 for displaying the information for distinguishing each port 101.

An optoelectronic device includes a photonic component. The photonic component includes an active side, a second side different from the active side, and an optical channel extending from the active side to the second side of the photonic component. The optical channel includes a non-gaseous material configured to transmit light.

There is provided an optical connector-incorporating plug properly assembled such that an optical fiber taken out from an end portion of an optical cable can have a fixed length. The optical connector-incorporating plug of the invention includes: a cable insertion component having an insertion hole in which an optical cable is inserted with an optical fiber being taken out from a cable end portion of the optical cable; a tubular member in which the cable end portion and the optical fiber are placed and in which the cable insertion component is fitted; a hole formed at a peripheral wall of the tubular member to check at least one of the cable end portion and the optical fiber in the tubular member; and a surrounding member mounted to the tubular member to surround the portion of the tubular member where the cable insertion component is fitted, thereby covering the hole.
