Embodiment Construction

[0068] Before explaining the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are described first.

[0069] With the rapid growth of network data center traffic, the requirements for the transmission rate between devices are getting higher and higher. Especially in the data center network, a large number of high-speed cables are required to interconnect the cabinets of the data center and the servers inside the cabinets, such as figure 1 As shown, the application provides a transmission cable technology, wherein the transmission cable has the characteristics of low dispersion and low group delay, can realize signal transmission in the terahertz and millimeter wave bands, and can meet the requirements of the growing data center scene. Data interconnection requirements.

[0070] The application provides a transmission cable, such as figure 2 As shown, the transmission cable includes at least one periodic...

Abstract

The present application discloses a transmission cable, which can realize high-speed interconnection and intercommunication between devices, and has broad application in fields such as data centers that require massive data transmission. The transmission cable includes a positive dispersion transmission section, a negative dispersion transmission section, and a dispersion matching section, wherein the cross-sectional diameter of the positive dispersion transmission section is smaller than the cross-sectional diameter of the negative dispersion transmission section. In the transmission cable, the dispersion matching section uses for connecting the positive dispersion transmission section and the negative dispersion transmission section. The transmission cable disclosed in the present application can achieve the effect of offsetting dispersion and reducing the total amount of group delay.

Description

technical field [0001] The present application relates to the field of communication interconnection, and in particular, to a transmission cable technology that can be applied to terahertz and millimeter wave bands. Background technique [0002] With the rapid growth of network data center traffic, the requirements for the transmission rate between devices are getting higher and higher. Taking the application scenario of the Top of Rack (TOR) architecture in a data center as an example, a large number of high-speed cables are required for interconnection between and within the data center cabinets. At present, Active Optical Cables (AOC) and Direct Attach Cable (DAC) are two main interconnection methods. However, AOC cables need to convert electrical signals into optical signals, or convert optical signals into electrical signals during the application process, and the optical transceivers at both ends of the optical cable need to provide photoelectric conversion and optica...
