Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber optic transmitters and receivers require separate video signal processing on mainboards, which can be complex and inefficient, as they only perform electrical-optical signal conversions without video processing capabilities.
Innovation Solution
Integration of a video signal processing chip within the SFP fiber module, which converts between electrical and optical signals and performs video signal processing functions such as HDMI, DP, and DVI processing, reducing the need for mainboard-based video signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video signal processing chip is added to the fiber module, then the fiber module functionality is enhanced and versatility is improved, but the manufacturing complexity increases
Solution Approach 1:
The SFP fiber module is designed with multi-functionality, supporting multiple video transmission standards (HDMI, DisplayPort, DVI) through an integrated video signal processing chip. This universal design allows a single module to handle various video formats, enhancing versatility while maintaining standardized manufacturing processes.
2Productivity
If separate video signal processing is performed on mainboards, then the fiber module design remains simple and standardized, but the overall system efficiency is reduced
Solution Approach 1:
The video signal processing is performed in advance within the SFP fiber module before signals reach the mainboard. The video signal processing chip converts and processes video signals to standardized formats (HDMI, DP, DVI) beforehand, so the mainboard only needs to perform simple electrical-optical conversion, thereby improving system efficiency.

AI summary
In a video signal transmission system using fiber optic cable, an improved optical transceiver module (fiber module) having integrated video signal processing capabilities can be used in video signal transmitters for video sources, video signal receivers for display devices, or video switching devices. The improved fiber module has a form factor complying with the Small Form-factor Pluggable standard, and a standard optical fiber connector. In addition to an optical transceiver, the improved fiber modules includes a ¼ inch signal processing chip programmed to perform video signal processing. The mainboard of the video signal transmitter or receiver or the video switching device has additional signal processing chips for processing non-video signals such as audio, data, network, RS-232, and IR remote control signals, but they do not perform video signal processing. Another embodiment is a fiber optic cable with an electrical signal connector module that integrates a video signal processing chip.
