Abstract

The invention relates to a design method for long-distance 40G QSFP communication active copper cable component. The component consists of two electrical transmission modules and a high-frequency communication copper cable with the length of 15 meters; the electrical transmission module comprises a power supply unit, a digital diagnosis and communication unit, a signal transmission unit, a signalreceiving unit and a 38PIN interface unit; the digital diagnosis and communication unit is connected with the signal transmission unit and the signal receiving unit; the power supply unit provides a working power supply; the digital diagnosis and communication unit is communicated with an external system; the signal transmission unit receives the signals of the external system and transmits the processed signals to the high-frequency communication copper cable; the signal receiving unit receives the signals of the high-frequency communication copper cable and transmits the processed signals to the external system; the 38PIN interface unit is connected with the internal electrical transmission module and the external system; and the high-frequency communication copper cable is connected with the two electrical transmission modules. The invention overcomes high-frequency attenuation characteristics, realizes that four pairs of 10G signals carry out 15m full duplex transmission and is used for occasions of high-performance calculation and data centers and the like.

Description

technical field [0001] The invention relates to a design method of a long-distance 40G QSFP communication active copper cable assembly, belonging to the technical field of communication. Background technique [0002] With the development of communication network technology, the advantages of large capacity and high speed have been widely used and popularized. Especially in recent years, the rapid increase of broadband services has put forward higher requirements for the capacity and density of network system equipment. Due to the limited area of ​​the mechanical panel of the system equipment, the number of module connection lines is limited. When using standard SFP+ connectors, the number of channels that can be accommodated is limited by the physical space. [0003] Many foreign companies have begun to develop QSFP 40G communication active copper cable components, but most of them are short-distance, generally no more than 10 meters, and optical fiber transmission is used f...
