Description

technical field [0001] The invention relates to the field of network equipment, in particular to a Gigabit Ethernet switching device. Background technique [0002] With the development of information technology and the popularization of Ethernet, various industries generally use Ethernet for information transmission, and some industries that require high transmission speed even use Gigabit Ethernet for information transmission between devices. Strict testing and simulation are generally required before use; generally, these devices are connected to standard test signal sources through Gigabit Ethernet, so that the standard test signal sources perform simulation tests on each device, while During the simulation test of a certain device, the Gigabit Ethernet of the device must be switched to the standard test signal source. At present, manual switching is generally used: First, manually connect a device to the standard test signal source through Gigabit Ethernet. The signal s...

Problems solved by technology

However, the above-mentioned Gigabit Ethernet switching method requires staff to connect and unplug each device, and the operation process is cumbersome, with low efficiency and a great waste of labor.

In addition to the traditional manual method, there is another method that uses ordinary relays or analog switches to switch Gigabit Ethernet signals. Although this method can realize automatic switching and improve efficiency, ordinary relays and analog switches belong to physical devices. switch, the transmission rate is low, and Gigabit Ethernet is a high-speed signal, so the switching rate of relays and analog switches cannot meet the rate requirements of Gigabit Ethernet; in addition, ordinary relays and analog switches will have electromagnetic induction during switching , the generation of these electromagnetic effects will affect the quality of communication, resulting in the failure of normal communication
