Embodiment Construction

[0067] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0068] figure 1 It shows a schematic flowchart of a signal speed-up method provided in this embodiment, including:

[0069] S101. The programmable logic gate array FPGA generates multiple channels of first test signals, and inputs each preset number of channels of the multiple channels of first test signals to a serializer.

[0070] Wherein, the first test signal refers to a test signal output by an FPGA (Field Programmable Gate Array, programmable logic gate array).

[0071] The preset number refers to the preset number of test signals input to a serializer, which can be set according to the number of test signals that can be received by the serializer. For example...

Abstract

The embodiment of the invention discloses a signal acceleration method and circuit, and the method comprises the steps that a programmable logic gate array (FPGA) generates a plurality of paths of first test signals, and inputs each preset number of paths of first test signals in the plurality of paths of first test signals to a serializer; each serializer performs serial acceleration processing on the preset number of paths of first test signals to generate high-speed test signals corresponding to each serializer; each serializer inputs a corresponding high-speed test signal to the first mechanical switch, and the first mechanical switch outputs any one high-speed test signal in all high-speed test signals. By the adoption of the signal acceleration method, the speed range capable of being tested based on the signal acceleration method can be larger.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a signal speed-up method and circuit. Background technique [0002] With the continuous development of optical communication technology, the transmission speed of the optical communication system using optical fiber as the transmission medium is also increasing. In order to ensure the efficient transmission of optical communication systems, how to ensure the stability and reliability of optical communication devices has become particularly important. [0003] In recent years, with the rise of new services and applications such as 4K, VR, and 5G, the traffic of optical communication networks has continued to grow rapidly. According to statistics, since 2013, the annual growth rate of global network traffic is about 30%, and the annual growth rate of network traffic in some countries even exceeds 40%. This has brought huge challenges to the networks of global telecom opera...
