Abstract
Abstract The present invention provides an optical module having a pluggable configuration, which enables to latch with the cage when the optical connector is mated with the receptacle. The optical module of the present invention is secured in the cage by latching the latch of the cage and the projection of the module. The actuator of the module, having a slab protruding into the optical receptacle, is able to slide along the direction the module is inserted into the cage. When the optical connector is in the optical receptacle, the slab of the actuator butts the optical connector and is prohibited to slide, accordingly, the optical module can not released from the cage.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
248 words
An optical module for communicating with an optical connector, said optical module being plugged in a space formed by a plurality of walls of a cage mounted on a host board, at least one of said walls of said cage including a resilient latch protruding into said space, comprising: an optical sub-assembly including an optical device therein; a housing providing a projection butting against an edge of said resilient latch when said optical module is plugged in said cage; a receptacle body having one end and another end, said one end including a receptacle for mating with said optical connector and said other end installing said optical sub-assembly, said receptacle body further including an opening; and an actuator slidable between a first position and a second position, said actuator including a pair of arms and a center portion connecting said arms, a span between said arms being longer than a length of said center portion, said center portion including a flange to be inserted into said opening of said receptacle body, said actuator pressing said resilient latch of the cage outward from said space at said second position, wherein said optical module is disengaged from said cage by sliding said actuator from said first position to said second position, and wherein said actuator is, when said optical connector is mated with said receptacle body, unable to slide from said first position to said second position by butting said flange against said optical connector inserted into said receptacle body.
Claim 2
Dependent Claim
248 words
An optical module for communicating with an optical connector, said optical module being plugged in a space formed by a plurality of walls of a cage mounted on a host board, at least one of said walls of said cage including a resilient latch protruding into said space, comprising: an optical sub-assembly including an optical device therein; a housing providing a projection butting against an edge of said resilient latch when said optical module is plugged in said cage; a receptacle body having one end and another end, said one end including a receptacle for mating with said optical connector and said other end installing said optical sub-assembly, said receptacle body further including an opening; and an actuator slidable between a first position and a second position, said actuator including a pair of arms and a center portion connecting said arms, a span between said arms being longer than a length of said center portion, said center portion including a flange to be inserted into said opening of said receptacle body, said actuator pressing said resilient latch of the cage outward from said space at said second position, wherein said optical module is disengaged from said cage by sliding said actuator from said first position to said second position, and wherein said actuator is, when said optical connector is mated with said receptacle body, unable to slide from said first position to said second position by butting said flange against said optical connector inserted into said receptacle body.
Claim 3
Dependent Claim
31 words
The optical module according to claim 1 , wherein said housing has a groove for receiving said arm of said actuator, said arm of said actuator being slidable in said groove.
Claim 4
Dependent Claim
47 words
The optical module according to claim 2 , wherein an end portion of said arm of said actuator is forked and said projection provided in said housing is disposed within said groove, said projection being put between said forked end portions of said actuator in said groove.
Claim 5
Dependent Claim
113 words
The optical module according to claim 2 , wherein said housing comprises an upper body including a pair of side walls and a lower body including a pair of side wails, said side walls of said upper body disposing said groove and said projection, said side walls of said lower body providing an opening and covering said side walls of said upper body, said resilient latch of said cage being butted against said projection by extending through said opening provided in said side walls of said lower body, and wherein said arm of said actuator is disposed between said side wall of said upper body and said side wall of said lower body.
Claim 6
Dependent Claim
20 words
The optical module according to claim 1 , further including a bail connected to said actuator for sliding said actuator.
Claim 7
Dependent Claim
36 words
The optical module according to claim 5 , wherein said bail is set in an upward position and in a downward position relative to said optical module when said actuator is set in said first position.
Claim 8
Dependent Claim
30 words
The optical module according to claim 5 , wherein said housing comprises an upper body and a lower body, said bail being coupled to said actuator via said lower body.
Claim 9
Dependent Claim
68 words
The optical module according to claim 5 , wherein said lower body includes a slot through which said bail passes to couple to said actuator, and wherein said first position of said actuator corresponds to a position where said bail is in one end of said slot, and said second position of said actuator corresponds to a position where said bail is in another end of said slot.
Claim 10
Dependent Claim
55 words
The optical module according to claim 5 , wherein said actuator further includes a pair of front side walls each extending from said arms, and wherein a span between said front side walls is greater than a length of said center portion, said bail being positioned inside of said front side walls of said actuator.
