Solution Overview

Problem

Conventional pluggable optical transceivers face overheating issues due to heat generation by electronic components, especially when plugged into a host device without adequate air circulation, leading to potential malfunctions.

Innovation Solution

The pluggable optical transceiver incorporates a thermal conductive layer in contact with heat-generating electronic components and an extended portion of the housing member to facilitate direct heat conduction and dissipation, with the extended portion protruding outside the host device to dissipate heat into the surrounding air, using thermally conductive materials and designs such as protrusions or fins.

Solution Approach 1:

The patent extracts the heat dissipation function from the internal enclosure by providing an extended portion that protrudes outside the host device. This allows heat to be conducted away from the electric circuit board to the external environment, resolving the contradiction between compact integration and temperature control.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The extended portion acts as a thermal intermediary, conducting heat from the electric circuit board to the surrounding air. This thermal bridge enables heat dissipation without requiring active cooling systems, maintaining device compactness while preventing overheating.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

Solution Approach 1:

The patent converts the harmful heat generated by integrated electronic components into a manageable thermal flow. By designing the extended portion to conduct heat away from the circuit board, the heat that would cause malfunction is instead channeled to the external environment for dissipation, allowing high-functionality integration.

Inventive Principle:
