Embodiment

[0042] Taking the electrical signal test of the 10-Gigabit optical port of a 10-Gigabit Ethernet switch connected by a 10-Gigabit cable as an example, the test system and method are further described:

[0043] Such as figure 1As shown, the test system in this example consists of the following parts:

[0044] Device under test: After the device under test is turned on and started up, it will always send 10 Gigabit electrical signals at the port connector of the device under test. The test engineer configures the device under test through the human-computer interaction interface to send a specific test pattern to the connector—PRBS pattern, which is the electrical signal test pattern required by the International Standards Organization SFF8431. The electrical signal is connected to the connector of the device under test through a 10G cable to the test fixture, and the electrical signal is transmitted to the test fixture;

[0045] 10 Gigabit cable: This cable is a cable defined...

Abstract

The invention relates to the 10-gigabit Ethernet communication test technology, discloses a system and method for testing 10-gigabit electrical signals and solves the problems of not high test precision, incomprehensive test and high cost in the prior art. The test system comprises a testes device, a test clamp and an oscilloscope. The testes device is connected with the test clamp through a 10-gigabit cable; and the test clamp is connected with a channel of the oscilloscope through a test coaxial cable. Besides, the invention also provides the method for testing the 10-gigabit electrical signals, and the method is suitable for testing the 10-gigabit electrical signals obtained through cable connection.

Description

technical field [0001] The invention relates to a ten-gigabit Ethernet communication testing technology, in particular to a system and method for testing ten-gigabit electrical signals. Background technique [0002] In recent years, with the large-scale rise of data centers and the outbreak of big data, high-density 10 Gigabit Ethernet switches, as bridge devices connecting servers, have rapidly emerged with extremely strong demand. At the same time, people have put forward higher requirements on the stability and adaptability of Ethernet switches. Therefore, for manufacturers of Ethernet communication equipment, faced with the increasingly high port rate of equipment, compatibility and consistency problems often occur due to poor testing of port signals. [0003] Since the physical interconnection of 10 Gigabit Ethernet with twisted pair is technically immature, and the transmission distance of twisted pair is limited by short distances, most high-density 10 Gigabit Ethern...
