Consistency testing method, device and storage medium

Abstract

Embodiments of the present application provide a consistency testing method, device, and storage medium, the method including: acquiring a test pattern in an optical signal transmitted by an optical transmitter, the optical signal being a non-return-to-zero Code two-key pulse amplitude modulation modulation generation; the test pattern is balanced and compensated, and the test pattern is used after the equalized compensation to synthesize the test eye pattern; according to the test eye pattern and the noise corresponding to the equalized compensation An enhancement coefficient, calculating the value of a first parameter, the first parameter is used to determine the degree of closure of the transmitter dispersion eye diagram of the optical transmitter; when the value of the first parameter is less than or equal to a preset threshold, It is determined that the conformance test of the optical signal passes. The consistency test method, device and storage medium provided in the embodiments of the present application can determine whether the optical signal transmitted by the optical transmitter adopting the NRZ-PAM2 mode can meet the use requirements of the optical receiver.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular to a conformance testing method, device and storage medium. Background technique [0002] Physical layer devices in a data communication network include components such as optical transmitters, channels (cables or optical fibers) and optical receivers. At present, manufacturers who produce optical transmitters conduct conformance tests on optical transmitters before they leave the factory. Through the conformance test, it can be accurately determined whether the optical transmitter is compatible with the channels and / or optical receivers provided by other manufacturers. [0003] At present, for optical transmitters that use non-return to zero pulse amplitude modulation 2 (NRZ-PAM2) to modulate optical signals, the "transmitter dispersion eye closure" eye closure, TDEC)" test parameters and its conformance test method, and perform a conformance test on t...
