  • Patent number: 8179676
    Abstract: Fluid-cooling technology developed for printed circuit boards (PCBs) and electronics assemblies is combined with optical-based interconnect technology, thereby enabling efficient fabrication of PCBs with free-space optical bearers. Since cooling components such as fans and heat sinks are no longer required on the PCB, the PCB is thinner and makes better use of a cooling substrate by also using it to carry optical signals. A card or a backplane supporting a plurality of active components can combine optical signals and cooling aspects in support of those components.

  • Patent number: 8111959
    Abstract: A method for making a multimode fiber optic subassembly includes alignment of an optical detector with a fiber termination of an optical fiber. The output of the optical detector (e.g. photocurrent) can be measured from light being transmitted through the optical fiber and detected by the optical detector. The end of the optical fiber and/or the optical detector can be positioned and angularly oriented in order to obtain relative maximum or peak output of the optical detector for a given position and orientation. The output of the optical detector can be monitored while mechanically manipulating, e.g. bending, flexing, shaking and/or twisting, the optical fiber, in order to verify that the positional relationship between the end of the optical fiber and the optical detector corresponds to a position and/or orientation that provides stable output from the optical detector.

    Abstract: A light receiving holder includes an abutting portion and a welded portion and the welded portion includes a ring-shaped projection which extends from the welded portion and whose cross-section is smaller as it is closer to the tip of the projection. A cap of a casing constituting a light receiving unit is received in a through-hole of the light receiving holder. The projection is brought into contact with a flange of the casing. Current is supplied between a lower electrode and an upper electrode to resistance-weld the projection to the flange. At this time, an angle is provided between a facing face of the lower electrode and a facing face of the upper electrode so that the light receiving holder is welded to the light receiving unit while an angle of the light receiving unit relative to the light receiving holder is adjusted.

  • Publication number: 20120002927
    Abstract: An optoelectronic module is provided that has an adapter that interacts with the tongue actuator of a module removal tool to actuate the cage tongue. Actuation of the cage tongue causes the latch disposed on the optoelectronic module to retract from the opening formed in the tongue to allow the optoelectronic module to be removed from the cage by the module removal tool. The adapter enables the module removal tool to be used to remove the module from the cage despite the fact that the distance between the optical reference plane and the mechanical actuation plane and the distance between the optical reference plane and the bottom surface of the cage may differ.
