Solution Overview
Problem
Users face challenges in determining the quality of physical connection cables, as the quality cannot be visually assessed, and professional inspection devices are expensive and inconvenient for individual users.
Innovation Solution
A network connection device equipped with a cable status detection module that can detect the status of a connection cable by sending a detection pulse signal and analyzing the feedback signal, even when the physical layer transmission circuit is in a disable state, allowing for both signal transmission and cable status detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a professional inspection device is used to detect cable status, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The network connection device is designed to perform both signal transmission and cable status detection functions. The physical layer transmission circuit can operate in different modes: normally transmitting data signals, and when disabled, allowing the cable status detection module to detect cable parameters by sending detection pulse signals through the interface module. This multi-functionality eliminates the need for separate professional inspection devices.
Solution Approach 2:
The network connection device performs self-diagnosis by detecting its own connection cable status. The cable status detection module uses the existing interface module and physical layer transmission circuit to send detection signals and analyze feedback, enabling the device to monitor its own connection health without requiring external professional equipment.
2Measurement precision
If a professional inspection device is used to detect cable status, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The network connection device performs self-diagnosis by detecting its own connection cable status. The cable status detection module uses the existing interface module and physical layer transmission circuit to send detection signals and analyze feedback, enabling the device to monitor its own connection health without requiring external professional equipment.
3Measurement precision
If the physical layer transmission circuit is disabled to detect cable status, then cable status detection accuracy is improved, but signal transmission ability deteriorates
Solution Approach 1:
The physical layer transmission circuit operates periodically, alternating between signal transmission mode and cable detection mode. During normal operation, it transmits data signals; when detection is needed, it disables transmission temporarily to send detection pulse signals through the interface module. This periodic switching allows both functions to coexist without permanent compromise.
Solution Approach 2:
The physical layer transmission circuit is designed to be dynamically switchable between different operational states. It can transition from a enabled state (performing signal transmission) to a disabled state (allowing cable detection), and back again. This dynamic capability allows the system to adapt its function based on operational needs.

AI summary
A network connection device and a cable status detection method are provided. The network connection device is configured to connect and detect a connection cable. The network connection device includes an interface module, a physical layer transmission circuit and a cable status detection module. The interface module connects the connection cable. The physical layer transmission circuit sends signals to the connection cable or receives signals from the connection cable through the interface module. The cable status detection module receives a notification notifying that the physical layer transmission circuit is in a disable state, and detects the status of the connection cable and generates a detection result when the physical layer transmission circuit is in the disable state. In this way, the network connection device may transmit data signals though the connected connection cable and detect the status of the connection cable.
