▎ 摘　　要

NOVELTY - The device has a housing (201) having at least first and second sidewalls that extend from an electrical coupling end to an optical coupling end and define a cavity. An optical component is mounted within the housing. The optical component in thermal communication with the housing is configured to communicate generated heat. A first heatsink is arranged on the first sidewall of the housing. One layer of graphene is arranged on the first heatsink. The thermal dissipation of heat generated by the optical component is increased. The first heatsink is provided with projections that extend from a surface defining the first sidewall. One layer of graphene is arranged on several projections. USE - Optical device e.g. quad form-factor pluggable (QSFP) transceiver or optical transceiver (claimed) for transmitting multiple channel wavelengths, used in optical transceiver system. ADVANTAGE - The layer of graphene advantageously utilizes this thermal behavior to draw and dissipate heat received from the sidewall through the layer, and provides a relatively large surface area by virtue of the geometry of the protrusions forming the associated heatsink. The graphene-coated cross-cut channels increase thermal performance based on graphene having a relatively high thermal conductivity and radiation emissivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an optical transceiver. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a pluggable optical transceiver module implementing the example optical transceiver system.
