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.

Abstract: A signal processing apparatus, an optical line terminal, and a communications system are provided. The signal processing apparatus includes a signal input interface, a signal output interface, a reset signal generation unit, a signal amplification and equalization unit, an enable signal generation unit, and N direct-current offset calibration loop units. The signal input interface is connected to the signal amplification and equalization unit, which is connected to the signal output interface and the enable signal generation unit; the enable signal generation unit is connected to the N direct-current offset calibration loop units, which are connected to the signal amplification and equalization unit; and the reset signal generation unit is connected to the N direct-current offset calibration loop units. Embodiments of the present invention are directed to reduce an LA burst settling time, thereby reducing physical overheads of a link.
