CFP Optical Transceiver Gasket Shielding Without Inner Space Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transceivers following the CFP standard require electrically conductive resin for shielding, which necessitates special tools and additional time for application, ultimately narrowing the inner space for installing components.
Innovation Solution
The optical transceiver employs tubed gaskets made of electrically conductive and elastic material, supported by a structure with inserts and hooks that secure the gaskets between the top and bottom housings without narrowing the inner space, using a support system that guides the gaskets and inner fibers to shield the housing effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrically conductive resin is used for shielding, then the inner space is restricted, but the shielding effect is achieved
Solution Approach 1:
The patent extracts the shielding function from the electrically conductive resin and implements it through a dedicated gasket structure. The gasket is positioned in a groove between the top and bottom housings, separating the shielding function from the space-constraining resin application, thereby achieving shielding without restricting inner space.
Solution Approach 2:
The gasket acts as an intermediary element that provides electrical shielding between the top and bottom housings. Instead of using resin that fills space, the gasket is inserted into a groove and pressed against the housings by a support structure, providing the same shielding effect without occupying inner space.
2Reliability
If electrically conductive resin is applied, then shielding is achieved, but special tools and additional time are required
Solution Approach 1:
The patent replaces the complex resin application process with a simple gasket insertion process. The gasket is a pre-formed component that can be easily installed without special tools, eliminating the need for resin application equipment and hardening processes.
Solution Approach 2:
The gasket structure is designed to be self-installing through the support mechanism. The support presses the gasket against the housings, creating a self-contained shielding solution that does not require external tools or additional processing steps.
3Reliability
If gasket is set in the housing, then shielding is achieved, but the inner space is narrowed
Solution Approach 1:
The patent segments the housing structure by creating a groove between the top and bottom housings. The gasket is placed in this groove, which is part of the housing structure itself, not the inner space. This segmentation allows the gasket to provide shielding without encroaching on the inner space where optical and electrical components are installed.
Solution Approach 2:
The gasket is positioned in the radial dimension (in the groove between housings) rather than occupying axial space within the inner volume. This dimensional placement allows the gasket to provide shielding while maintaining the full inner space for component installation.

Function Achieved in This Case
This solution allows for effective shielding of the inner space without restricting the space for optical and electrical components, eliminating the need for special tools and reducing the time required for resin hardening, while maintaining the CFP standard compliance.
Implementation Method 1
The electrically conductive gasket covers a gap formed between the ceiling of the top housing and the top of the side wall of the bottom housing
Implementation Method 2
An optical transceiver providing an electrically conductive and elastic gasket for shielding a housing has disclosed

AI summary
An optical transceiver of the CFP type having a gasket set within the slot is disclosed. The optical transceiver provides the slots in respective sides of the housing to pass the screws therein for fastening the optical transceiver to an electrical plug prepared in the host system. A support is also set within the slot so as to extend along the outer wall of the slot and not to interfere with the screw. The support pushes the gasket against the outer wall so as to cover a gap inherently formed between the top housing and the bottom housing.
