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.
