Optical transceiver including latch for release prevention and optical communication assembly having the same

An optical transceiver, configured to be inserted into a cage in pluggable manner, comprising:

• a housing;
• a fastening component disposed on the housing, wherein the fastening component is movable with respect to the housing in a releasing direction from an electrical port of the optical transceiver toward a fiber optic port of the optical transceiver, the fastening component comprises a fastening arm and a confining portion connected with each other, the fastening arm extends in the releasing direction and is detachably fastenable with the cage, and the confining portion extends in a direction non-parallel to the releasing direction;
• a latch pivotally disposed on the housing to be at either an unlocking position or a locking position, wherein the latch is pivotable between the unlocking position and the locking position without movement of the fastening component with respect to the housing in the releasing direction;
• and
• a pull tab fixed to the fastening component;
• wherein when the latch is at the unlocking position, a detachment of the fastening component from the cage by a movement of the fastening component is allowed, and
• when the latch is at the locking position, at least part of the latch is located between the pull tab and the fiber optic port of the optical transceiver and at least part of the confinement portion is located between the latch and the fiber optic port in the releasing direction, and the detachment of the fastening component from the cage is prohibited by interference between the latch and the confining portion.

An optical communication assembly, comprising:

• a cage;
• and
• an optical transceiver inserted into the cage, and the optical transceiver comprising:
• a housing;
