Patch Panel Structure With Asymmetric Port Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional patch panel structures experience severe alien crosstalk due to the close spacing of network ports, which compromises the signal-to-noise ratio (SNR) in high-speed data transmission environments.
Innovation Solution
A patch panel structure is designed with two parallel jack rows of network ports, where odd-numbered ports are arranged in one direction and even-numbered ports in an opposite direction, with increased spacing between RJ-45 jack ends and IDC ends to minimize alien crosstalk, adhering to standards like ANSI/TIA-568-C.2 and ISO/IEC 11801.

Engineering Contradiction Analysis
1Quantity of substance
If network ports are spaced closely together to maximize port density, then the quantity of network ports per unit area increases, but alien crosstalk between adjacent ports increases severely
Solution Approach 1:
The patent applies asymmetry by implementing different spacing patterns for odd and even numbered ports. Odd ports are spaced at a first distance while even ports are spaced at a second distance, creating an asymmetric arrangement that maximizes separation between adjacent ports of different channels. This asymmetric spacing pattern effectively reduces alien crosstalk while maintaining high port density on the patch panel.
2Reliability
If the distance between adjacent network ports is increased to reduce alien crosstalk, then signal-to-noise ratio improves, but the port density decreases
Solution Approach 1:
The patent utilizes dimensional arrangement by organizing ports in alternating odd and even rows with different spacing characteristics. Rather than simply increasing uniform spacing in one dimension, the invention creates a two-dimensional spacing pattern where odd ports in one row alternate with even ports in adjacent rows at optimized distances. This dimensional approach allows maintaining high port density while ensuring adequate separation for SNR requirements.
3Ease of manufacture
If uniform spacing is used for all network ports, then manufacturing and installation are simplified, but alien crosstalk cannot be adequately minimized for high-speed transmission
Solution Approach 1:
The patent applies local quality by implementing different spacing parameters for different groups of ports. Specifically, odd numbered ports are spaced at a first distance from their neighbors, while even numbered ports are spaced at a second distance. This localized differentiation of spacing quality allows each port group to be optimally positioned for minimizing crosstalk, while still maintaining a regular enough pattern for ease of manufacture and installation.

AI summary
A patch panel structure includes a first jack row including a plurality of first network ports each having RJ-45 jack ends aligned in a first direction and arranged in a first row; a second jack row including a plurality of second network ports each having RJ-45 jack ends aligned in a second direction and arranged in a second row, wherein the first jack row and the second jack row are parallel, whereas the first direction and the second direction are opposite. Minimal alien crosstalk occurs between the network ports of the patch panel structure, thereby meeting strict transmission standards.
