High-speed data transmission line

Technical Field

The utility model relates to a communication materials field provides a high-speed transmission cable for QSFP very much.

Background

In the wide application of portable electronic devices such as mobile phones, digital cameras, digital video cameras, tablet computers, notebook computers, personal digital assistants, and mobile players in life, people often need to use signal transmission cables such as data lines or power lines to perform data transmission between different electronic devices or between electronic devices and personal computers or to perform electrical energy transmission processes such as charging between different electronic devices. With the progress of the times, the network information is prosperous, the network information amount is larger and larger, the requirement on the transmission speed is higher and higher, and the support on hardware is absolutely needed.

QSFPQuad Small Form-factor plug: the quad SFP interface (QSFP), which was created to meet the market demand for higher density, high speed pluggable solutions. QSFP can be a fiber optic solution and has better speed and density than the 4-channel CX4 interface. Because four-channel data transmission can be supported at the speed of 10Gbps per channel under the same port volume of the XFP, the density of the QSFP can reach 4 times of the XFP product and 3 times of the SFP + product. The system is mainly used for 1. a switch, a router and a host adapter bus; 2. enterprise storage; 3. high density, high speed I/O; 4. multi-channel interconnects, and the like. QSFP + high-speed cables are widely applied to short-distance high-speed interconnection such as a gigabit network card, a gigabit switch, a server, a supercomputer, cloud computing and a cloud storage network. How to ensure the stability of the transmission signal of the high-speed cable becomes an important link.

Detailed Description

As shown in fig. 1-2:

the utility model provides a high-speed data transmission line, includes overcoat layer 1, and overcoat layer 1's central point puts from inside to outside and includes two heart yearn conductors 2 in proper order, and every heart yearn conductor 2 is wrapped up by insulating layer 3 separately, and two insulating layers 3 are wrapped up by 4 local parcels in first layer shielding tape, then are wrapped up around 5 whole parcels in area, again by 6 parcels in second layer shielding tape 5 outside, 6 outer both ends departments of second layer shielding tape set up the ground wire 8 of horizontal direction, 8 outsides of parcel second again in ground wire wrap up around area 7. And a second layer of shielding tape 6 is arranged outside the wrapping tape 5 and is wrapped in the opposite direction of the wrapping direction of the first layer of shielding tape 4. First layer shielding area 4's effect is wrapped up fixedly to two insulating layers 3 in an orientation, then wraps up for the second time by wrapping up tape 5, all wraps up first layer shielding area 4 and two insulating layers 3 together, insulating layer 3 is polyolefin or teflon, and two insulating layers 3 are the circular tangent horizontal position. And then the second layer of shielding tape 6 is wrapped again in the opposite direction of the first layer of shielding tape 4, and finally the second layer of shielding tape 7 is wrapped with the ground wire 8 integrally. All the ground wires 8 and the core wire conductors 2 are on the same horizontal line. The final shape is that the outer sleeve layer 1 is horizontal with the upper and lower side surfaces, and protrudes outwards with the ground wire 8 as the two ends.
