Claim of US Patent No. 10,219,412

1. A connector assembly configured to be received by a radio unit, the connector assembly comprising: a printed wiring board (PWB) configured to be at least partially disposed within the radio unit when in an operational configuration, wherein the PWB defines an extension at least partially disposed exterior to the radio unit when in the operational configuration; one or more optoelectronic components configured to convert between optical signals and electrical signals supported by the PWB, wherein at least a portion of the one or more optoelectronic components are disposed on the extension of the PWB; and a heat sink housing attached to the PWB and disposed adjacent the radio unit when in the operational configuration, wherein the heat sink housing is configured to enclose the extension of the PWB and the portion of the one or more optoelectronic components disposed on the extension, and wherein the heat sink housing is configured to dissipate heat from the portion of the one or more optoelectronic components to an exterior environment of the connector assembly; and further comprising a separation plate disposed between the radio unit and the heat sink housing, wherein the separation plate is configured to promote thermal isolation between the heat sink housing and the radio unit.
