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： 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.
摘要翻译：光收发器模块设置有细长的捕捉拉片，其使得光收发器模块能够容易地从保持架中分离和拉出，而不必首先从模块拔下光纤电缆，而不必旋转保释。因此，需要由用户执行以从笼中移除模块的手动操作的数量大大降低，这使得简化了移除过程并使得设计非常适合于在热插拔环境中使用。另外，脱钩拉片避免了针或螺钉的需要，从而通过降低在制造过程中模块被损坏的可能性来提高制造成品率。此外，通过从设计中消除销钉或螺钉和吊环，随着时间的推移，可以减少可以磨损的移动部件。

摘要： Heat dissipation resources are allocated in an optical communications module based on the sensitivity of electrical and optoelectronic components of the module to temperature. Components that have a higher sensitivity to temperature are allocated a greater proportion of available heat dissipation resources than components that have a lower sensitivity to temperature. In addition, heat dissipation resources that are allocated to components that have different sensitivities to temperature are thermally decoupled from one another.

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： Methods and apparatuses are provided for performing electromagnetic interference (EMI) containment in a parallel optical communications system. The apparatus includes a curved surface formed in the system housing near the opening through which a stack of ribbon cables passes, and a spring device. The stack of ribbon cables is sandwiched in between the curved surface of the housing and the spring device. The spring device exerts a force on the stack of ribbon cables that presses the stack against the curved surface of the housing and forms a sharp bend in the stack just before the stack passes through the opening in the housing. Because EMI radiation is restricted to propagation along the sharply bent pathway of the stack of ribbon cables, most or all of the EMI radiation traveling along that pathway is either attenuated or reflected before it reaches the opening.

摘要： A parallel optical communications device is provided that has an OSA that includes at least one heat dissipation block having a slot formed in a lower surface thereof that contains a weldable insert. Likewise, an upper surface of the mounting device of the ESA has at least one slot formed therein that contains a weldable insert. After the OSA is placed in contact with the ESA and optically aligned with the ESA, the OSA is secured to the upper surface of the mounting device of the ESA by welding together the respective weldable inserts contained in the respective slots in the OSA and in the mounting device of the ESA. The welding process results in an extremely strong welded joint between the OSA and the ESA that prevents relative movement between the OSA and the ESA if external forces that are exerted on the OSA and/or on the ESA.
