Optical Transceiver Module Segmentation for Maintenance and Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transceivers have a rigid design that complicates maintenance and flexibility in high-speed communication networks, as the optical components, including the TOSA and ROSA, are often integrated on a circuit board within a housing, making it difficult to replace or maintain individual components like the light emitter without opening the housing.
Innovation Solution
The optical communication system separates the light emitter from the ROSA, with the light emitter located in a light source module and optically coupled to the ROSA via fibers, allowing for independent replacement and operation without opening the receiver housing, and includes a heat conductive structure for efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical components (TOSA and ROSA) are integrated on a circuit board within a housing, then the device structure is compact and complete, but the maintenance flexibility and ease of replacing individual components deteriorates
Solution Approach 1:
The optical transceiver is divided into separate functional modules: the light emitter module (containing TOSA) and the ROSA module, which are independently replaceable. This segmentation allows maintenance personnel to replace only the faulty component without disassembling the entire housing, thereby improving maintenance flexibility while maintaining a complete device structure.
Solution Approach 2:
The light emitter is extracted from the integrated circuit board structure and placed in a separate, easily replaceable module. This extraction enables independent replacement of the light emitter without affecting other components, resolving the contradiction between compact integration and maintenance ease.
2Object-affected harmful factors
If optical components are integrated on a circuit board, then the device structure is simplified, but the electromagnetic interference between components increases
Solution Approach 1:
By segmenting the optical components into separate modules (light emitter module and ROSA module), the patent reduces electromagnetic interference between these components. The physical separation while maintaining functional integration through optical coupling achieves both reduced EMI and simplified structure.
3Temperature
If the light emitter is integrated with ROSA on the same circuit board, then the device is compact, but the heat dissipation efficiency deteriorates
Solution Approach 1:
The patent separates the light emitter (which generates significant heat) from the ROSA into different modules. This segmentation allows for independent thermal management of each module, with dedicated heat conductive structures for the light emitter, thereby improving heat dissipation efficiency while maintaining a compact overall device through modular architecture.
