8 February 2005 Study and implementation using FPGA of RTT in EPON
Author Affiliations +
Nowadays, EPON technology is regarded as one of the best candidate technology for next generation broadband access technology. In this paper, the architecture of EPON is introduced first. The upstream in EPON adopts TDMA/TDM technology, and it is necessary to know the exact RTT(Round Trip Time), the principle of RTT measurement (ranging) and RTT compensation are introduced. We use Xilinx FPGA SpartanII chip series to realize ranging function module, the main idea of implementation is given in this paper, and this can be used for further study of hardware implementation.
