LED LAN Cable Connector High-Speed Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED LAN cable connectors experience decreased data transmission speed and data blocking when external power is applied, particularly at high speeds exceeding 100Mps, such as in CAT5E, CAT6, and CAT7 standards, due to the LED system interpreting the power source as a signal and causing interference.
Innovation Solution
The proposed solution includes a substrate unit with a power source terminal, a condenser to process the external power, and a light emitting unit that emits light only when a valid data signal is present, preventing interference by generating a pulse signal that matches the standards for high-speed data transmission, ensuring the LED emits light correctly at both ends of the cable without disrupting data flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If external power is applied to the LAN cable connector to power the LED, then the LED can be illuminated to identify cable connections, but data transmission speed decreases and data blocking occurs at high speeds exceeding 100Mps
Solution Approach 1:
The patent introduces a coupling capacitor as an intermediary component between the external power source and the LED circuit. This capacitor blocks the direct passage of power frequency signals (50/60Hz) into the data transmission lines, allowing only the DC component to reach the LED. This resolves the contradiction by enabling LED illumination while preventing power interference from degrading high-speed data transmission.
Solution Approach 2:
The patent extracts and separates the power signal processing function from the data transmission function by using the coupling capacitor to remove the AC power component from the external power source before it reaches the LED circuit. This extraction prevents the power frequency signals from interfering with the high-speed data transmission channels.
2Ease of operation
If external power is applied to the LED circuit in the LAN cable connector, then the LED can indicate cable connection status, but the LED system interprets the power source as a signal causing interference
Solution Approach 1:
The coupling capacitor serves as a mediator that allows the DC power component to reach the LED for illumination while blocking the AC power frequency signals from entering the data transmission lines. This intermediary component enables cable identification functionality while preventing the harmful effect of power source interference with data signals.
Solution Approach 2:
The patent converts the potentially harmful external power source into a beneficial dual-function element: the DC component powers the LED for cable identification, while the AC component is blocked by the coupling capacitor. This transforms what could be a source of interference into a useful power source for the LED indicator.
