Abstract

The invention relates to the field of network communication, in particular to a Gigabit Ethernet bypass device. The Gigabit Ethernet bypass includes: a physical interface module and a signal conversion module, the physical interface module includes a signal acquisition unit, and the signal conversion module includes an analog-to-digital conversion unit, a first digital-to-analog conversion unit and a second digital-to-analog conversion unit. The Gigabit Ethernet bypass provided by the present invention converts the analog signal into a digital signal through an analog-to-digital conversion unit to repair the collected data (also referred to as an electrical signal), and sends the signal to the bypass port and Before sending the signal to the receiving port of the tested line, use the digital-to-analog conversion unit for conversion to ensure that the signal can be normally received by the receiving port of the tested line and enable the bypass port to receive normally, while ensuring that the Ethernet topology does not change Under the premise of ensuring the integrity of the data (electrical signal), it solves the deficiencies of the prior art.

Description

technical field

[0001] The invention relates to the field of network communication, in particular to a Gigabit Ethernet bypass device. Background technique

[0002] Engineering systems (including aircraft, missiles, satellites, automobiles, etc.) must go through a large number of tests before the design is finalized, including the test of data acquisition on the Ethernet interface of each device.

[0003] At present, all data collection tests on Ethernet ports are implemented through switches or physical bypasses. If the test is performed through a switch, it is necessary to transfer the Ethernet interconnected between the devices to the switch, but this test method directly changes the Ethernet topology of the system under test, and cannot guarantee the integrity of the system under test; if Test by physical bypass. For 100M Ethernet, it is necessary to use filters and amplifiers to filter and amplify the electrical signal, which can realize the basic bypass data collectio...
