Abstract
A pluggable optical module may include a substrate. The pluggable optical module may include a compressible sliding thermal interface disposed on the substrate to contact a riding heatsink. The compressible sliding thermal interface material may be compressed to fill interstices between a first surface of the substrate and a second surface of the riding heatsink. The compressible sliding thermal interface may protrude from the first surface of the substrate such that insertion of the pluggable optical module into a cage compresses the compressible sliding thermal interface to achieve a threshold thermal boundary resistance.
Claims20
An optical device that is configured to be slidably engaged with a heatsink, the optical device comprising:
- a substrate;
- and
- a sliding thermal interface disposed on the substrate,
- wherein the sliding thermal interface includes a flexible interface structure that encloses an interface filling material, and
- wherein the sliding thermal interface is configured to be compressed with a threshold clamping force when the optical device slidably engages the heatsink.
An optical module configured to removably engage another component, the optical module comprising:
- a substrate,
- a thermal interface disposed on the substrate,
- wherein the thermal interface includes an outer interface structure that encloses a filling material, and
- wherein, when the optical module removably engages the other component, the thermal interface is configured to fill interstices between the substrate and the component to achieve a threshold thermal boundary resistance between the optical module and the other component.
An electro-optic transceiver, comprising:
- a substrate that is configured to be removably inserted into a cage;
- and
- a thermal interface disposed on an upper surface of the substrate,
- wherein the thermal interface includes an outer structure that encloses a filling material, and
- wherein the thermal interface is configured to fill interstices within the cage when the substrate is removably inserted into the cage.
