Optical Transceiver Unlocking Key Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transceiver modules lack security features, allowing them to be unplugged during operations without authorization, posing a risk to data transmission security.
Innovation Solution
An optical transceiver system with a removable key that includes two fingers to unlock the module from a cage and a locking mechanism, ensuring the module can only be removed by authorized personnel, using a key that locks to the transceiver and allows for secure unplugging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a built-in unlocking mechanism is provided in the optical transceiver module, then the module can be unlocked and unplugged from the cage, but security is compromised as the module can be removed during operations without authorization
Solution Approach 1:
The unlocking function is segmented into two separate components: the optical transceiver module and the removable key. The module contains only the locking structure (locking tabs and locking gaps), while the unlocking action is performed by a separate key with unlocking fingers. This segmentation ensures that the module itself cannot be removed without the key, thereby maintaining security while still allowing authorized unplugging operations.
2Ease of operation
If a built-in unlocking mechanism is provided in the optical transceiver module, then the module can be unlocked, but the manufacturing complexity and cost increase
Solution Approach 1:
The unlocking mechanism is extracted from the optical transceiver module and placed into a separate removable key. The module is simplified to contain only the passive locking structure (locking tabs and locking gaps), while the active unlocking components (unlocking fingers, spring, pivot block) are relocated to the key. This extraction reduces the manufacturing complexity and cost of the module while preserving the unlocking function in the key.
3Reliability
If the optical transceiver module is locked to the cage, then security is improved, but the module cannot be unplugged during operations
Solution Approach 1:
The removable key acts as an intermediary between the locked state and the unplugged state. The key's unlocking fingers engage with the locking tabs through the locking gaps, mediating the release of the locking mechanism. This intermediary approach maintains the locked state for security while enabling controlled unplugging when the key is present and used by authorized personnel.
