A connector assembly includes a connector, an optical waveguide and a circuit board having a through-hole and a transmitter/receiver configured to transmit and/or receive light signals. The connector is interlockingly and releasably connected to the circuit board via a fastening element which is passed through the through-hole and connected to the circuit board. The connector has a receiving chamber which at least partially borders the transmitter/receiver. A lens unit is disposed in the receiving chamber and light-conductively connects the transmitter/receiver to the optical waveguide. A locking element is movably disposed on the connector. The locking element is disposed at least partially within the receiving chamber and secures the lens unit in the receiving chamber. The locking element is movable into a final latched position in which the locking element extends at least partially into the through-hole and blocks release of the fastening element from the circuit board.

A communication system having a circuit board with an airflow opening includes a receptacle cage configured to be mounted to the circuit board adjacent a communication connector. The receptacle cage has walls including a front wall, a rear wall and side walls defining a cavity. A module channel is defined in the cavity configured to receive a pluggable module. The module channel has a module port at the front wall that receives the pluggable module. An airflow channel is defined by at least one of the walls of the receptacle cage located between the module channel and the circuit board. The airflow channel is configured to be in flow communication with the airflow opening in the circuit board for cooling the pluggable module in the module channel. The airflow channel has an airflow port at the front wall.

A butt closure base includes a base housing defining a plurality of cavities. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities. Each of the plurality of wedge assemblies includes an outer cover, a second gel, and a main pressure plate in contact with the second gel. The main pressure plate is movable along a longitudinal axis to apply pressure to the second gel. Each of the plurality of wedge assemblies further includes a latch assembly. The latch assembly includes an adjustable tab and a stop member movable between a first position which limits movement of the adjustable tab and a second position in which movement of the adjustable tab is not limited by the stop member.

The present invention provides a receptacle structure for an optical connector comprising a receptacle body, and a first housing. The receptacle body has a first end and a second end for providing optical connector inserted thereto, respectively. Two sides of the first end respectively have first flexible plate having first attaching structure. The first housing, folded by a single piece material, is a closed structure having a first through hole wherein two walls of the first housing have first coupling structure for coupling to the attaching structure when the first end of the receptacle body is inserted into the first through hole whereby the first housing is completely assembled with the receptacle body. In addition, an optical communication device having the receptacle structure is also provided in which the optical connector can be inserted into the receptacle structure for optical communication.

A heat exchange assembly includes a plate stack having fin plates and spacer plates interleaved with the fin plates in the plate stack. Each fin plate has fin sides extending between a fin lower edge and a fin upper edge. Each spacer plate has spacer sides extending between a spacer lower edge and a spacer upper edge. The fin upper edges of the fin plates are located above the spacer upper edges. Air flow channels are formed in gaps between the fin plates above the spacer plates. The fin lower edges and the spacer lower edges define a lower thermal interface configured to be in thermal communication with an electrical component to dissipate heat from the electrical component. The fin plates are independently movable relative to the spacer plates in the plate stack to independently articulate the fin lower edges and the spacer lower edges at the lower thermal interface. The heat exchange assembly includes a plate stabilizer structure positioning the fin upper edges relative to each other. The plate stabilizer structure includes plate stabilizers having stabilizing fingers. The stabilizing fingers coupled to at least two fin plates to control spacing of the fin upper edges of the corresponding fin plates.

A pluggable optical module includes: a casing with an internal space; a latching pocket disposed on a side wall of the casing; and a latch plane on a surface of the latching pocket. The surface is a beveled surface, and the beveled surface delimiting the latch plane has an angle of between 3 to 15 degrees.

A butt closure base includes a base housing defining a plurality of cavities. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities.
