Abstract
A conformance testing method including: obtaining a testing symbol pattern in an optical signal; performing equalization compensation on the testing symbol pattern; generating a testing eye pattern; calculating a value of a first parameter based on the testing eye pattern and a noise enhancement coefficient, where the first parameter is used to determine a transmitter dispersion eye pattern closure degree of the optical transmitter; and when the value of the first parameter is less than or equal to a preset threshold, determining that conformance testing on the optical signal succeeds.
Claims20
A transmitter dispersion eye pattern closure degree testing method, comprising:
- obtaining, from an optical transmitter, a testing symbol pattern in an optical signal;
- performing equalization compensation on the testing symbol pattern to obtain an equalized testing symbol pattern;
- generating a testing eye pattern through composition using the equalized testing symbol pattern;
- and
- calculating, based on the testing eye pattern and a noise enhancement coefficient that corresponds to the equalization compensation, a value of a first parameter, wherein the first parameter is for determining a transmitter dispersion eye pattern closure degree of the optical transmitter.
A transmitter dispersion eye pattern closure degree testing apparatus, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the transmitter dispersion eye pattern closure degree testing apparatus to:
- obtain, from an optical transmitter, a testing symbol pattern in an optical signal;
- perform equalization compensation on the testing symbol pattern to obtain an equalized testing symbol pattern;
- generate a testing eye pattern through composition using the equalized testing symbol pattern;
- and
- calculate a value of a first parameter based on the testing eye pattern and a noise enhancement coefficient that corresponds to the equalization compensation, wherein the first parameter is for determining a transmitter dispersion eye pattern closure degree of the optical transmitter.
