Abstract
A 10G rate OLT terminal transceiver integrated chip based on XGSPON and DFB laser includes: a burst mode receiver RX which amplifies an optical signal from each ONU client into an electrical signal through a burst transimpedance amplifier TIA, processes amplitude detection, and outputs the signal whose amplitude met the threshold requirements to a host, and comprises a fast recovery module to discharge charges in an AC coupling capacitor to achieve multi-packet transmission without mutual interference, thereby meeting the timing sequence requirement of the XGSPON protocol; a continuous mode transmitter TX which receives the electrical signal attenuated by a PCB board, and selects a bypass BYPASS path or a clock data recovery CDR path for activation according to a degree of attenuation; and a digital control unit DIGIITAL which communicates with the host and provides control signals for the burst mode receiver RX and the continuous mode transmitter TX.
