Description

technical field

[0001] The invention belongs to the communication equipment testing technology, in particular to a universal testing method for interface single boards of broadband products. Background technique

[0002] With the development of communication technology, there are more and more types of interface boards for broadband products, and the speed is getting faster and faster. Therefore, higher requirements are put forward for the testing of such boards.

[0003] The interface type single board is generally simple in structure, mainly realizes the physical layer function of the communication network, and provides the service interface with the link layer. The composition of general broadband interface boards is as follows: figure 1 shown. It is mainly composed of physical layer processing chips, link layer interfaces, optical and electrical interfaces, and serial-to-parallel conversion units.

[0004] Broadband interface boards are always connected to the transce...
