Communication device

A communication device, comprising:

• a first PCB;
• a second PCB positioned parallel to the first PCB;
• a first shielding cage, fixed to the first PCB, and defining at least one first receiving space to receive at least one transceiver module therein, the first shielding cage comprising at least one first retaining tab extending inwardly into a front opening of the at least one first receiving space;
• and
• a second shielding cage, fixed to the second PCB, and neighboring the first shielding cage, the second shielding cage defining at least one second receiving space to receive at least one transceiver module therein, and comprising at least one second retaining tab extending inwardly into a front opening of the at least one second receiving space;
• wherein the first and second PCBs collectively define a space therebetween, and the first shielding cage and the second shielding cage are accommodated in the space;
• wherein each of the transceiver modules received in the first and second shielding cages comprises a release mechanism configured with a release portion and a trigger, wherein the release portion is structured to collaborate with one of the first and second retaining tabs to release the corresponding transceiver module from the first or second shielding cage, the triggers disposed on corresponding sides of the transceiver modules close to the first and the second PCBs.
