Abstract

The invention provides a four-channel small package interface line, relating to the technical field of communication equipment. The four-channel small package interface line is formed by a plurality of center line pairs and a plurality of parallel line pairs. A filling layer is arranged outside a whole body formed by the center line pairs. The periphery of the filling layers is provided with the plurality of parallel line pairs. A whole body formed by six parallel line pairs is wrapped by a shielding layer. An outer shielding layer is arranged outside the shielding layer. An outer sheath is arranged outside the outer shielding layer. Both the center line pairs and the parallel line pairs are formed by two conductors, each conductor is wrapped by a modified PE insulator, a whole body formed by two modified PE insulators is wrapped by a copper foil shielding layer with the thickness of 30um, a small outer coat is arranged outside the copper foil shielding layer with the thickness of 30 micrometers, and a line number marking layer is arranged outside the small outer coat. The modified PE is employed, the insulation intensity is greatly improved, the copper foil shielding layer with the thickness of 30um is used for line pair shielding, a line performance test fully satisfies technical requirements, the shielding effect is good, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a four-channel small package interface line. Background technique [0002] The Quad Small Form Factor Pluggable (QSFP+) solution is designed for high-density applications. System components include Electromagnetic Interference (EMI) Shielding, Active Optical Cables (AOC), Passive Copper Cable Assemblies, Active Copper Cable Assemblies, Optical MTP Cable Assemblies, Optical Loopbacks, Host Connectors, Connector and Cage Cascade Integration. [0003] In the prior art, because the insulating material is PE, its strength is insufficient, and the shielding effect of the wire to the aluminum foil is not good, resulting in poor attenuation, return loss, and differential to common mode signals, which need to be improved urgently. Contents of the invention [0004] The purpose of the present invention is to aim at the defects and deficiencies of the prior art, and provi...
