CPC H04Q 11/0067 (2013.01) [H04B 10/038 (2013.01); H04B 10/0795 (2013.01)] | 9 Claims |
1. A 10 G rate OLT terminal transceiver integrated chip based on XGPON and DFB laser, comprising:
a burst mode receiver RX, a continuous mode transmitter TX and a digital control unit DIGIITAL,
wherein an optical signal received from each one ONU client is processed through a burst TIA into an electrical signal, then the burst-mode receiver RX amplifies the electrical signal, processes double-detection for amplitude and frequency of the electrical signal, to determine if an amplitude and a waveform pulse width of the electrical signal meet threshold requirements related to meeting a XGPON protocol, and outputs a detection result of the electrical signal to a host, and uses a fast recovery module to control a timing to meet the XGPON protocol;
the continuous mode transmitter TX receives an original high speed electrical signal attenuated by a PCB board, and in response to a degree of attenuation, selects a bypass BYPASS path for transmission or outputs the signal after a signal quality is improved by processing through a clock data recovery CDR path; and
the digital control unit DIGIITAL is used to provide control signals for the burst mode receiver RX and the continuous mode transmitter TX.
