Ethernet Fiber Switch for Interference-Resistant Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Ethernet cabling for data transmission within buildings faces issues such as signal attenuation and interference, requiring numerous cables and conversion devices, which are costly and difficult to install due to size constraints and interference from high-voltage power lines.
Innovation Solution
A multi-port Ethernet fiber switch converts Traditional Digital Data (TDD) to Optical Data (OD) for transmission over optical lines, which are then converted back to TDD at integrated in-wall mounted data access stations, reducing the number of devices needed and allowing for efficient, interference-resistant data distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional Ethernet cabling is used for data transmission, then data can be transmitted within buildings, but signal attenuation and interference occur over relatively short distances requiring frequent amplification
Solution Approach 1:
The patent substitutes electrical signal transmission (mechanical/electromagnetic field in copper cables) with optical signal transmission (light pulses in fiber optic cables). This replacement eliminates signal attenuation and interference issues associated with traditional Ethernet cabling, enabling long-distance data transmission without frequent amplification while maintaining high reliability.
2Reliability
If optical systems are used to transmit data over long distances, then signal attenuation and interference are eliminated, but TDD must be converted to OD and back, requiring additional conversion devices
Solution Approach 1:
The patent combines the optical-to-electrical conversion function with the existing Ethernet switch and router devices. The fiber optic interface is integrated directly into these network devices, eliminating the need for separate conversion devices. This merging approach maintains signal quality benefits while reducing device complexity and cost.
3Adaptability or versatility
If multiple Ethernet cables are installed to support multiple Internet devices, then each device can be connected, but the installation becomes costly and difficult due to size constraints and interference from high-voltage power lines
Solution Approach 1:
The patent replaces multiple individual copper Ethernet cables with a single fiber optic cable that can carry multiple data streams simultaneously. This substitution dramatically reduces the number of cables needed, simplifies installation by eliminating interference concerns with high-voltage power lines, and maintains the ability to support multiple Internet devices through wavelength division multiplexing or other optical multiplexing techniques.

AI summary
A multi-port Ethernet fiber switch converts the TDD to OD and then provides the OD to multi-port Ethernet fiber switch ports for transmission on optical lines connected to the multi-port Ethernet fiber switch ports. The OD on the multiple optical lines is then transmitted to multiple integrated converter/receiver in-wall mounted data access stations through the multiple optical lines. Each integrated converter/receiver in-wall mounted data access station includes an integrated OD to TDD converter/receiver that is positioned in a cavity in the wall in which the integrated converter/receiver in-wall mounted data access station resides. Each integrated converter/receiver in-wall mounted data access station includes one or more data ports, such as standard RJ-45 ports.
