    摘要： An optical transceiver module is provided with an elongated delatching pull tab that that enables an optical transceiver module to be easily delatched and pulled from a cage without having to first unplug optical fiber cables from the module and without having to rotate a bail. Thus, the number of manual actions that need to be performed by a user to remove the module from a cage is drastically reduced, which makes simplifies the removal process and makes the design well suited for use in hot-pluggable environments. In addition, the delatching pull tab obviates the need for pins or screws, thereby improving manufacturing yield by reducing the likelihood that the module will be damaged during the manufacturing process. In addition, by eliminating pins or screws and a bail from the design, there are fewer moving parts that can wear out over time.

    摘要： A lens device has a body with a base surface, a plurality of lenses on the base surface, and a plurality of projections extending above the base surface and defining a protective plane above the plurality of lenses. The plurality of projections can include, for example, post-like regions, ridge-like regions, or a combination thereof.

    摘要： A Z-pluggable optical communications module (OCM) is provided that contains multiple parallel OCMs (POCMs) and that is configured to be removably plugged into an opening formed in a front panel of an optical communications system. When the Z-pluggable OCM is plugged in a forward Z-direction into the opening formed in the front panel, an actuator mechanism is actuated to impart motion to the Z-pluggable OCM in the downward Y-direction to cause the Z-pluggable OCM to be mounted on an upper surface of a motherboard PCB. In order to unplug the Z-pluggable OCM, the actuator mechanism is actuated to impart motion to the Z-pluggable OCM in the upward Y-direction to cause it to be dismounted from the motherboard PCB.

    摘要： Independent assemblies are compliantly mounted to a force transfer mechanism to optically align and thermally couple a device under test (DUT) to a test apparatus. A first assembly includes an optical connector. The first assembly has an alignment feature and a first compliant interface. A second assembly includes a thermal control member and force transfer members coupled to a structure. A passage permits a portion of the arm of the first assembly to extend through the structure. The force transfer members provide respective seats for an additional compliant interface. The alignment feature engages a corresponding feature to align the optical connector with the DUT before the compliant interfaces compress under an external force. Compliant mounting of the assemblies accommodates manufacturing tolerances in the DUT so that contact forces on the DUT are relatively consistent and thereby enable consistent optical and thermal coupling between the test apparatus and the DUT.

    摘要： A flexible dust cover is provided for use with a parallel optical communications module for preventing airborne matter, such as dirt, dust, and gases from entering the module. The flexible dust cover fits snugly to the module to protect components of the module and the optical pathways of the module from airborne matter. The flexible dust cover has an elasticity that allows it to be temporarily deformed from its original shape to a stretched state by application of a stretching force to enable the module to be inserted into a central opening formed in the cover. The force is then removed, causing the cover to attempt to return to its original, non-stretched shape. When this happens, interior surfaces of the cover form a snug fit about exterior surfaces of the module. This snug fit fills in air gaps in the module that would otherwise be exposed to the environment.
