Rapid test system and method of QSFP(Quad Small Form-factor Pluggable)+ to 4SFP(Small Form-factor Pluggable)+ high speed cable

Abstract

The invention discloses a rapid test system of a QSFP(Quad Small Form-factor Pluggable)+ to 4SFP(Small Form-factor Pluggable)+ high speed cable. The system comprises a switch unit, wherein the switch unit comprises a master switch in support of a virtual local area network VLAN division function, and two slave switches; a terminal unit which comprises two test terminals connected with the slave switches; and a control terminal connected with the master switch. A to-be-tested QSFP+ to 4SFP+ high speed cable is in communication connection with the master switch and the slave switches. According to the rapid test system of the QSFP+ to 4SFP+ high speed cable provided by the invention, it is possible to test the transmission performance of 4 channels at one time; the test time is reduced; the test efficiency is effectively improved; repeated plugging can be prevented; and the reliability of the test data is improved. The invention also provides a method applying the rapid test system. According to the method, the system is enabled to have high stability, high precision and high controllability.

Description

technical field [0001] The invention relates to a test system used in the factory inspection or maintenance of high-speed cables. More specifically, the present invention relates to a quick test system and method used in the factory inspection or maintenance of QSFP+to 4 SFP+ high-speed cables. Background technique [0002] The full name of QSFP is Quad Small Form-factor Pluggable (four-channel small hot-swappable), which was born to meet the market's demand for higher-density high-speed pluggable solutions. This 4-channel pluggable interface transmission The rate reached 40Gbps. And QSFP+to 4 SFP+ is a high-speed cable with a 40Gbps QSFP+ interface at one end and four 10Gbps SFP+ interfaces at the other end. Therefore, when testing the transmission performance of a QSFP+to 4 SFP+ high-speed cable, it is usually necessary to perform performance tests on the data transmission channels of the 4 SFP+ interfaces in sequence. [0003] Generally speaking, the traditional test m...

AI Technical Summary

Problems solved by technology

[0004] Although in the existing production technology, although in the production process, QSFP+to 4 SFP+ high-speed cables will have defective products, but generally speaking, the yield rate is still very high, and there are certain problems in the existing testing methods. One is that it needs to test the transmission performance of a single 4 SFP+ channels one by one, which leads to low test efficiency. The second is that repeated plugging and unplugging during the test process can easily cause a channel to be missed, while other The occurrence of multi-channel measurement is not conducive to the improvement of test accuracy
