Pluggable transceiver retainer
An optoelectronic module may include a housing enclosing at least one optical transmitter or receiver, a slider configured to move with respect to the housing, and a retainer configured to engage both the slider and the housing to retain the slider with respect to the housing. The slider may include a resilient tab and at least one protrusion configured to engage a cage sized and shaped to receive the housing. The retainer may include a first end portion configured to abut the resilient tab of the slider.
1. An optoelectronic module for use with a cage having an opening therein, the module comprising:
a housing enclosing at least one optical transmitter or receiver, the housing configured to insert in a first direction into the opening of the cage;
a slider configured to move with respect to the housing, the slider including a resilient tab and at least one protrusion, the at least one protrusion configured to engage selectively in a second direction with the cage; and
a retainer configured to engage both the slider and the housing to retain the slider with respect to the housing, the retainer including a first end portion configured to abut the resilient tab of the slider.
2. The optoelectronic module of claim 1 , wherein the retainer is sized and shaped to surround at least a portion of the slider.
3. The optoelectronic module of claim 1 , wherein the first end portion extends towards an interior of the retainer.
4. The optoelectronic module of claim 1 , the retainer further comprising a second end portion configured to abut in the first direction against a first shoulder on the housing.
5. The optoelectronic module of claim 4 , wherein the first end portion and the second end portion are positioned on a first side of the retainer, further comprising an engaging portion positioned on a second side of the retainer, opposite the first side, the engaging portion configured to abut in the second direction against a second shoulder on the housing.
6. The optoelectronic module of claim 5 , wherein the first end portion and the second end portion are coplanar.
7. The optoelectronic module of claim 1 , wherein the housing defines an opening sized and shaped to receive the first end portion of the retainer to permit the first end portion to interface with the resilient tab of the slider.
8. The optoelectronic module of claim 1 , further comprising a handle coupled to the slider.
9. The optoelectronic module of claim 8 , wherein the retainer is sized and shaped to surround at least a portion of both the handle and the slider.
10. The optoelectronic module of claim 8 , wherein the retainer includes a first side configured to abut a first surface of the housing facing the handle and a second side configured to abut a second surface of the housing facing the handle facing away from the handle.
11. The optoelectronic module of claim 1 , wherein the slider is configured to move in a direction parallel to a longitudinal axis of the housing.
12. The optoelectronic module of claim 1 , the slider comprising at least one arm extending along the housing, wherein the protrusion of the slider is positioned on the arm.
13. The optoelectronic module of claim 1 , wherein the resilient tab of the slider extends towards a direction parallel to a longitudinal axis of the housing and is biased towards the housing.
14. The optoelectronic module of claim 1 , wherein the retainer is substantially planar and is formed of a resilient material.
15. The optoelectronic module of claim 1 , the retainer comprising a resilient wire, wherein the first end portion is a first end of the resilient wire.
16. A method to keep an optoelectronic module installed in a cage, the method comprising:
inserting the module in a first direction in an opening of the cage;
locking the module in a second, opposite direction in the opening by:
moving a slider on a housing of the module to a locked position, and engaging a protrusion on the slider against a first resilient tab of the cage; and
retaining the slider in the locked position on the housing by:
positioning a first end portion of a retainer in an opening defined in the housing of the optoelectronic module such that the first end portion of the retainer abuts a second resilient tab of the slider; and
engaging the retainer with both the slider and the housing to retain the slider in the locked position with respect to the housing.
17. The method of claim 16 , further comprising bending the retainer to surround at least a portion of the slider.
18. The method of claim 16 , wherein the retainer is substantially planar and formed of a resilient material, further comprising bending the retainer to a non-planar configuration prior to positioning the retainer to surround at least a portion of the slider.
19. The method of claim 16 , wherein engaging the retainer with the housing includes abutting a first side of the retainer with a first surface of the housing facing a handle and abutting a second side of the retainer with a second surface of the housing facing away from the handle.
20. The optoelectronic module of claim 1 , wherein the slider is configured to move between first and second positions relative to the housing, the at least one protrusion with the slider in the first position configured to engage the cage in the second direction, the at least one protrusion with the slider in the second position configured to disengage from the cage, the retainer configured to retain the slider in the first position with respect to the housing.
