Integrated Optronic Transceiver Module for Fiber Cut Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical fibre telecommunications systems require separate equipment for protection against fibre cuts, leading to increased installation, maintenance complexity, and costs due to the need for additional protection devices, which also result in redundant alarms and inefficient management.
Innovation Solution
An integrated optronic transceiver module that includes both supervision and switching capabilities, allowing for seamless switching between main and backup optical fibres within the module, eliminating the need for external protection devices and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate protection devices are used for fibre cut protection, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines the protection device functions (supervision module and switching module) directly into the optronic transceiver module. The supervision module monitors optical signal quality and the switching module switches between main and backup fibres, integrating these previously separate functions into a single unified device, thereby reducing installation and maintenance complexity while maintaining reliability
Solution Approach 2:
The optronic transceiver module is designed to perform multiple functions: optical signal transmission/reception, fibre cut supervision, and automatic switching between main and backup fibres. This multi-functional design eliminates the need for separate dedicated protection devices, reducing overall system complexity while providing comprehensive protection
2Reliability
If separate protection devices are used, then reliability is improved, but cost increases
Solution Approach 1:
By merging the supervision and switching functions into the existing transceiver module, the patent eliminates the need to manufacture and deploy separate protection devices. This integration reduces component count, simplifies assembly, and lowers overall manufacturing costs while maintaining the same level of reliability protection
3Reliability
If separate protection devices are used, then fibre cut protection is achieved, but alarm management becomes inefficient
Solution Approach 1:
The supervision module and switching module are integrated within the transceiver, allowing unified alarm management. The system generates a single alarm when fibre cuts are detected, eliminating the redundancy of multiple alarms from separate devices. The integrated architecture enables centralized monitoring and control, simplifying operation and maintenance

AI summary
An optronic transceiver module capable of implementing an optical bidirectional communication of the point to point type via at least one main optical fibre is disclosed. The optronic transceiver module includes a first optical module for supervising an uplink signal received via the main optical fibre delivering a first supervision result, a first optical module for switching the bidirectional communication via the main optical fibre to a bidirectional communication via a backup optical fibre, and vice versa, the first optical switching module being controlled by the first optical supervision module depending on the first supervision result delivered.
