Patent number: 8449203Abstract: CXP is a telecommunications connector standard based on cage assemblies originally designed for copper cables. Optical transceivers dissipate more heat than copper cables, however, so cage assemblies designed for copper cables cannot remove heat adequately for proper transceiver operation. One embodiment of the inventive cage assemblies removes heat from an optical transceiver with a heat spreader, which protrudes through an aperture in a cage, and a compressible gap pad in thermal contact with the heat spreader. Inserting the optical transceiver into the cage places the transceiver in thermal contact with a heat spreader and pushes the heat spreader out of the cage, which, in turn, causes the gap pad to come into thermal contact with a heat pipe and/or a heat sink. The embodiment provide a low mechanical profile to support high-density circuit board configurations for high-density optical connectivity systems, such as used in Dense Wavelength Division optical networking.Type: GrantFiled: September 2, 2010Date of Patent: May 28, 2013Assignee: Tellabs Operations, Inc.Inventor: Thomas John Downs

Publication number: 20130094145Abstract: A heat sink and method of fabrication are provided for removing heat from an electronic component(s). The heat sink includes a heat sink base and frame. The base has a first coefficient of thermal expansion (CTE), and includes a base surface configured to couple to the electronic component to facilitate removal of heat. The frame has a second CTE, and is configured to constrain the base surface in opposing relation to the electronic component, wherein the first CTE is greater than the second CTE. At least one of the heat sink base or frame is configured so that heating of the heat sink base results in a compressive force at the base surface of the heat sink base towards the electronic component that facilitates heat transfer from the electronic component. A thermal interface material is disposed between the base surface and the electronic component.Type: ApplicationFiled: October 12, 2011Publication date: April 18, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Levi A.
