Pluggable Optical Transceiver Actuator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing CFP optical transceivers have limited inner space due to the conventional fastening mechanism with screws, which restricts the accommodation of larger optical and electrical components required for 400 Gbps applications, leading to increased power dissipation and size constraints.
Innovation Solution
A pluggable optical transceiver design featuring a housing with a fastening screw that engages with a rail, an actuator that synchronously latches with the rail motion, and a coil spring mechanism to secure the transceiver, allowing for a wider inner space and easier engagement/disengagement with the host system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two fastening screws are provided in respective sides of the front panel to securely engage the CFP optical transceiver with the host system, then the secure engagement is improved, but the inner space of the housing is restricted
Solution Approach 1:
The invention extracts the fastening function from the conventional screw mechanism and relocates it to the actuator that engages with the rail. The fastening screw is modified to only perform the fastening function after the actuator has established the mechanical connection, thereby removing the space-consuming dual-screw configuration and maximizing the inner space for optical and electrical components.
Solution Approach 2:
The fastening mechanism is segmented into two functional stages: first, the actuator protrudes from the housing side and latches with the rail to establish secure engagement; second, the fastening screw engages with the host system to fix the position. This segmentation allows each component to perform its specific function efficiently without occupying excessive space simultaneously.
2Productivity
If optical components are made larger to support 400 Gbps applications, then the data transmission capability is improved, but the housing inner space becomes insufficient
Solution Approach 1:
The invention repositions the fastening mechanism from occupying horizontal space within the housing to utilizing the vertical dimension and external housing surfaces. The actuator engages with the rail from the side of the housing, and the fastening screw extends from the front panel to the rear end, effectively using the length and width dimensions rather than consuming valuable inner space for fastening functions.
3Power
If electrical components are designed for higher power dissipation to handle 400 Gbps operations, then the data processing capability is improved, but the housing design becomes more constrained
Solution Approach 1:
The invention extracts the fastening function from the internal housing structure and implements it through the actuator-rail mechanism and modified screw engagement. This removes the need for complex internal fastening structures that would constrain the housing design, thereby providing greater flexibility to accommodate electrical components with higher power dissipation requirements.
