The slider may include at least one protrusion configured to engage a cage sized and shaped to receive the housing. The optoelectronic module may include a bail rotatably coupled to the housing. The bail may be configured to actuate the slider when the bail is rotated. The optoelectronic module may include a retainer including an occlusion member sized and shaped to be positioned inside a port of the optoelectronic module. The retainer may define a surface configured to engage with the bail. ## Claims ### Claim 1 An optoelectronic module comprising: a housing enclosing at least one optical transmitter or receiver; a slider configured to move with respect to the housing, the slider including at least one protrusion configured to engage a cage sized and shaped to receive the housing; a bail rotatably coupled to the housing, the bail configured to actuate the slider when the bail is rotated; and a retainer including an occlusion member sized and shaped to be positioned inside a port of the optoelectronic module, the retainer defining a surface configured to engage with the bail. ### Claim 2 (depends on 1) The optoelectronic module of claim 1, wherein the surface of the retainer engaging with the bail retains the bail and the slider in a fixed position with respect to the housing. ### Claim 3 (depends on 1) The optoelectronic module of claim 1, wherein the surface of the retainer is configured to abut a handle of the bail when the occlusion member is positioned inside of the port. ### Claim 4 (depends on 1) The optoelectronic module of claim 1, the retainer comprising a body extending between a first end portion and a second end portion, the occlusion member positioned on the first end portion. ### Claim 5 (depends on 4) The optoelectronic module of claim 4, the surface of the retainer extending from the second end portion in direction towards the first end portion. ### Claim 6 (depends on 1) The optoelectronic module of claim 1, wherein the surface of the retainer abutting the handle of the bail prevents the bail from rotating when the occlusion member is positioned inside of the port. ### Claim 7 (depends on 1) The optoelectronic module of claim 1, wherein the surface of the retainer is defined by a shoulder positioned on a body of the retainer. ### Claim 8 (depends on 7) The optoelectronic module of claim 7, wherein the shoulder defining the surface of the retainer extend parallel to the occlusion member. ### Claim 9 (depends on 1) The optoelectronic module of claim 1, wherein the retainer abuts a portion of the bail when the occlusion member is positioned in the port to retain both the bail and the slider in a fixed position with respect to the housing. ### Claim 10 (depends on 1) The optoelectronic module of claim 1, wherein the retainer prevents the bail from rotating when the retainer is positioned in the port and consequently prevents the slider from moving with respect to the housing to an unlocked position. ### Claim 11 (depends on 1) The optoelectronic module of claim 1, wherein the retainer is formed of a resilient material such that the occlusion member deforms as it is positioned in the port. ### Claim 12 (depends on 1) The optoelectronic module of claim 1, wherein the retainer is formed of a plastic or polymer material. ### Claim 13 (depends on 1) The optoelectronic module of claim 1, wherein the protrusion of the slider is configured to engage a corresponding resilient tab of the cage. ### Claim 14 (depends on 1) 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. ### Claim 15 (depends on 1) The optoelectronic module of claim 1, wherein a resilient tab of the slider extends towards a direction parallel to a longitudinal axis of the housing and is biased towards the housing. ### Claim 16 (depends on 1) The optoelectronic module of claim 1, wherein the retainer disables a release mechanism of the slider when engaged with the bail. ### Claim 17 A method comprising: positioning an occlusion member of a retainer into a port of an optoelectronic module to occlude the port; and abutting a surface of the retainer with a bail of the optoelectronic module, the bail rotatably coupled to a housing of the optoelectronic module and configured to actuate a slider when the bail is rotated; wherein abutting the surface of the retainer with the bail of the optoelectronic module prevents the bail from rotating. ### Claim 18 (depends on 17) The method of claim 17, wherein the surface of the retainer abuts a handle of the bail to prevent the bail from rotating. ### Claim 19 (depends on 17) The method of claim 17, wherein abutting the surface of the retainer with the bail of the optoelectronic module prevents the bail from rotating thereby disabling a slider coupled to the bail. ### Claim 20 (depends on 17) The method of claim 17, further comprising removing the retainer from the port of the optoelectronic module to permit the bail to rotate and actuate a slider.
