20110268390 | ACTIVE OPTICAL CABLE THAT IS SUITED FOR CONSUMER APPLICATIONS AND A METHOD - An active optical cable is provided that is well suited for consumer applications. In contrast to known Quad Small Form-Factor Pluggable (QSFP) active optical cables, the active optical cable incorporates at least one consumer input/output (CIO) optical transceiver module that is well suited for consumer applications. The plug housing of the known QSFP active optical cable has been modified to house at least one CIO optical transceiver module that utilizes laser diode and photodiode singlets, rather than the parallel laser diode and photodiode arrays used in the known QSFP active optical cables. These features reduce the overall cost of the active optical cable and make it well suited for consumer applications. | 11-03-2011 |
20120027362 | DELATCH DEVICE HAVING BOTH PUSH AND PULL OPERABILITY FOR USE WITH AN OPTICAL TRANSCEIVER MODULE, AND A METHOD - An optical transceiver module is provided with a delatch device that is configured for pushing and pulling an optical transceiver module into and out of a cage. The delatch device includes an elongated handle having at least one strength member integrally formed therein or secured thereto that provides the handle with a sufficient moment of inertia to prevent the handle from bending or buckling when a force is being applied to the elongated handle to push an optical transceiver module into a cage. The elongated handle allows a module to easily be inserted into a cage by a user without the user having to directly access the front face of the module. | 02-02-2012 |
20120251057 | OPTICAL TRANSCEIVER MODULE HAVING A DEFORMABLE HEAT SINK STRUCTURE - A heat dissipation solution is provided that includes a heat sink structure that has a very high thermal conductivity and includes elements or features that can be deformed to increase the contact surface areas between the heat sink structure and the module casing, thereby decreasing thermal resistance. By increasing the thermal conductivity and the sizes of the surface areas that are used for transferring heat, the temperature difference between the temperature of the light source and the temperature of the module casing can be decreased to enable the light source to be operated at higher data rates. Furthermore, deformation of the deformable features also removes space between the optical subassembly and the module body caused by mechanical tolerance differences that occur during manufacturing. | 10-04-2012 |
20120257355 | BALANCED COOLING SYSTEM AND METHOD FOR HIGH-DENSITY STACKED CAGES - Systems and methods for balanced cooling of electrical systems, including electrical systems containing transceivers used in electrical and optical communication. An electrical system includes a cage, where the cage has a top, front and bottom. The cage contains a plurality of upper bays disposed in the front of the cage. Each of the plurality of upper bays is configured to receive a transceiver. The cage also contains a plurality of lower bays disposed in the front of the cage. Each of the lower bays is configured to receive a transceiver. Additionally, each of the plurality of upper bays is stacked on one of the plurality of lower bays. An upper heat sink extends from the outer surface of the top of the cage and a lower heat sink extends from the outer surface of the bottom of the cage. | 10-11-2012 |
20120266434 | METHODS AND APPARATUSES FOR PROTECTING FLEXIBLE (FLEX) CIRCUITS OF OPTICAL TRANSCEIVER MODULES FROM BEING DAMAGED DURING MANUFACTURING AND ASSEMBLY OF THE MODULES - Methods and apparatuses are provided for preventing flex circuits of optical transceiver modules from being damaged during the process of manufacturing and assembling the optical transceiver modules. Preventing the flex circuits from being damaged during the manufacture and assembly processes increases yield and decreases costs. In addition, the methods and apparatuses that are used to prevent the flex circuits from being damaged also allow the processes of forming the mechanical bends and inserting the modules into their respective housings to be automated. Automating these processes further increases yield and decreases costs. | 10-25-2012 |
20130022309 | OPTO-ELECTRONIC COMMUNICATION MODULE HAVING RETAINER FOR ALIGNING OPTICAL PORTS - An opto-electronic communication module includes a housing, an electro-optical assembly, and a retainer that helps maintain alignment of an optical port. The electro-optical assembly includes a circuit substrate, an opto-electronic communication device mounted on the circuit substrate, and an optics module having an optical connection portion extending into the opening of the housing to define the optical port. The retainer can be, for example, a clip that contacts the housing and fits over the optical connection portion of the optics module to maintain the optical connection portion in alignment with the opening of the housing. | 01-24-2013 |
20140161398 | OPTICAL COMMUNICATION MODULE WITH FIBER SUBMOUNT AND LATCHING OPTICS ASSEMBLY - In an optical communication module, a fiber submount is mated with an optics assembly to optically align an optical fiber retained in a groove in the fiber submount with an optics element of the optics assembly. The fiber submount has a resiliently biased latch portion that engages the optics assembly to provide a resilient retaining force between the optics assembly and the fiber submount. The force retains the optics element in optical alignment with the fiber optical axis. | 06-12-2014 |
20140168906 | PLUGGABLE DATA COMMUNICATION MODULE WITH COMPLIANT PUSH-PULL TAB - A data communication module tab is sufficiently compliant in off-axis directions that it resists damage from forces in such off-axis directions, yet is sufficiently rigid in the direction of its longitudinal axis that a person can insert the data communication module into a cage and withdraw it from a cage by pushing and pulling the tab, respectively. | 06-19-2014 |
20140169749 | PLUGGABLE DATA COMMUNICATION MODULE WITH SLIDER-CRANK DELATCH MECHANISM - A delatch mechanism for disengaging a data communication module from a cage includes an actuator handle and a T-shaped crank connected at a wrist pivot to the handle and connected at a crank pivot to the module housing. The crank pivots to lift a pin out of engagement with the cage when a user pulls on the actuator handle, causing it to slide relative to the housing. | 06-19-2014 |
