Abstract
A 10 G rate OLT terminal transceiver integrated chip based on XGPON and DFB laser includes: a burst mode receiver RX, a continuous mode transmitter TX and a digital control unit DIGIITAL. The burst mode receiver RX amplifies an optical signal from each ONU client into an electrical signal through a burst TIA, processes double-detection for amplitude and frequency of the electrical signal, outputs the signal whose amplitude and waveform pulse width meet the threshold requirements to the host, and uses a fast recovery module to control the timing to meet the XGPON protocol. The continuous mode transmitter TX receives the electrical signal attenuated by the PCB, and selects the bypass BYPASS path or the clock data recovery CDR path according to the degree of attenuation. The digital control unit DIGIITAL is used to provide control signals for the burst mode receiver RX and the continuous mode transmitter TX.
