A receptacle cage includes shielding walls forming a module channel configured to receive a pluggable module. The shielding walls include a top wall, a first side wall extending from the top wall to a bottom of the module channel, and a second side wall extending from the top wall opposite the first side wall to the bottom of the module channel. The top wall, the first side wall and the second side wall form the module channel. The receptacle cage includes a first polarization tab extending into the module channel from the first side wall. The first polarization tab is configured to interface with the pluggable module for keyed loading of the pluggable module in the receptacle cage.

A shielding cage assembly includes a mating end surface and at least one group of stacked mating spaces. The mating spaces stacked in a same group are communicated at a rear of the shielding cage assembly to form a receiving space for accommodating a receptacle connector. The shielding cage assembly further includes an accommodating space between two adjacent mating spaces. The accommodating space extends through two opposite outer side walls of the shielding cage assembly. One side of the accommodating space extends through the mating end surface, and another side of the accommodating space extends to the receiving space. The shielding cage assembly is easy to assemble a heat dissipation member and has good heat dissipation performance. A receptacle connector assembly having the shielding cage assembly is also disclosed.

An example optoelectronic module includes a housing that extends between a first end portion and a second end portion. The optoelectronic module includes a printed circuit board (PCB) that includes an electrical connector at the second end portion of the housing, at least one transmitter electrically coupled to the PCB and optically coupled with at least one optical fiber, at least one receiver electrically coupled to the PCB and optically coupled with at least one optical fiber, and at least one electromagnetic interference (EMI) attenuating component formed of a plastic material that is configured to attenuate EMI. The EMI attenuating component is configured to attenuate EMI generated by one or more other components of the optoelectronic module.

Methods, systems, and apparatuses for electromagnetic shielding are provided, particularly for semiconductor packages and/or printed circuit boards. For example, an optical device covered by an RF can may be attached to a substrate. The RF can may have a first aperture for an optical path of the optical device. A deposition layer may provide electromagnetic shielding in conjunction with the RF can. The deposition layer may include one or more portions that are deposited at the same time, including a first portion with an aperture that narrows the aperture of the RF can. The deposition layer, after being deposited, may be cured. The deposition layer and RF can may provide electromagnetic shielding for the optical device.

An interconnection system including a pluggable transceiver and a connector disposed in a cavity of a conductive cage. The pluggable transceiver may include a latching mechanism for locking to the conductive cage. The latching mechanism may include a pair of latches positioned on opposite sides of the pluggable transceiver. The latches may be spatially offset from each other along a longitudinal and/or vertical direction. Corresponding latching tabs in the conductive cage may be disposed in the same relationship, even in a ganged configuration when latching tabs for adjacent cavities are formed in a common wall between cavities. Cammed surfaces of a release mechanism, centered between latching edges of the transceiver latches may impart a latch releasing force at a central portion of the latching tab forcing the lathing tab back into the common wall, reducing rotational moment applied in prior designs, such as QSFP ganged cages.
