Locking arrangements for pluggable optical subassembly modules

A optical module comprising:

• a pluggable housing defining a cavity to receive an optical component, the pluggable housing configured to removably couple into a receptacle of an equipment cage;
• and
• a locking arrangement coupled to the pluggable housing to allow the pluggable housing to releasably lock within the receptacle, the locking arrangement including:
• a lock actuator coupled to the pluggable housing and configured to transition the pluggable housing between a locked orientation and an unlocked orientation, the locked orientation to prevent removal of the pluggable housing from the receptacle of the equipment cage and the unlocked orientation to allow removal of the pluggable housing from the receptacle of the equipment cage, and wherein the lock actuator includes first and second handle coupling members extending therefrom that define an axis of rotation R2;
• and
• a handle member defining first and second slots to receive the first and second handle coupling members of the lock actuator, respectively, therein and rotate about the axis of rotation R2 to transition the handle member between at least a first orientation and a second orientation;
• wherein the first handle coupling member includes at least a first protrusion and the first slot includes a corresponding recess to receive the first protrusion of the first handle coupling member, and wherein the first handle member is configured to remain at the first orientation in an absence of a user-supplied force based on the first protrusion of the first handle coupling member being disposed within the recess of the first slot;
• wherein the first handle coupling member defines a second protrusion, and wherein the second protrusion is configured to be disposed within the recess of the first slot based on the handle member being rotated and transitioned to the second orientation, and wherein the handle member remains in the second orientation in the absence of a user-supplied force based on the second protrusion being disposed within the recess of the first slot.

An optical transceiver module comprising:

• a pluggable housing configured to removably couple into a receptacle of an optical transceiver cage;
• and
• a locking arrangement coupled to the pluggable housing to allow the pluggable housing to releasably lock within the receptacle, the locking arrangement including:
• a lock actuator coupled to the pluggable housing and configured to transition the pluggable housing between a locked orientation and an unlocked orientation, the locked orientation to prevent removal of the pluggable housing from the receptacle of the optical transceiver cage and the unlocked orientation to allow removal of the pluggable housing from the receptacle of the optical transceiver cage, and wherein the lock actuator includes first and second handle coupling members extending therefrom that define an axis of rotation R2;
• and
• a handle member providing an internal hinge based at least in part on first and second slots defined by the handle member, the first and second slots configured to receive the first and second handle coupling members of the lock actuator, respectively, and define an axis of rotation R2 about which the handle member rotates to transition between at least a first orientation and a second orientation;
• a transmitter optical subassembly (TOSA) arrangement disposed in the pluggable housing;
• and
• a receiver optical subassembly (ROSA) arrangement disposed in the pluggable housing;
• wherein the first slot includes a first projection disposed therein and the second slot includes a second projection disposed therein, and wherein an imaginary line drawn along the axis of rotation R2 intersects with the first and second projections of the first and second slots, respectively, when the first and second handle coupling members are disposed within the first and second slots of the handle member, respectively.

An optical transceiver module comprising:

• a pluggable housing configured to removably couple into a receptacle of an optical transceiver cage;
• and
• a locking arrangement coupled to the pluggable housing to allow the pluggable housing to releasably lock within the receptacle, the locking arrangement including:
• a lock actuator coupled to the pluggable housing and configured to transition the pluggable housing between a locked orientation and an unlocked orientation, the locked orientation to prevent removal of the pluggable housing from the receptacle of the optical transceiver cage and the unlocked orientation to allow removal of the pluggable housing from the receptacle of the optical transceiver cage, and wherein the lock actuator includes first and second handle coupling members extending therefrom that define an axis of rotation R2;
• and
• a handle member providing an internal hinge based at least in part on first and second slots defined by the handle member, the first and second slots configured to receive the first and second handle coupling members of the lock actuator, respectively, and define an axis of rotation R2 about which the handle member rotates to transition between at least a first orientation and a second orientation;
• a transmitter optical subassembly (TOSA) arrangement disposed in the pluggable housing;
• and
• a receiver optical subassembly (ROSA) arrangement disposed in the pluggable housing;
• wherein the first handle coupling member includes at least a first protrusion and the first slot includes a corresponding recess to receive the first protrusion of the first handle coupling member, and wherein the first handle member is configured to remain at the first orientation in an absence of a user-supplied force based on the first protrusion of the first handle coupling member being disposed within the recess of the first slot;
• wherein the first protrusion of the first handle coupling member is configured to be disposed within the first slot of the handle member when the first handle member is in the first orientation and the second orientation, and wherein the first handle coupling member defines a second protrusion, and wherein the second protrusion is configured to be disposed within the recess of the first slot based on the handle member being rotated and transitioned to the second orientation, and wherein the handle member remains in the second orientation in the absence of a user-supplied force based on the second protrusion being disposed within the recess of the first slot.
