|The GPON (G.984) Reed-Solomon code is fully compliant with the GPON (G.984) standard. It supports the upstream data rate of 2488.32 Mbps and 1244.16 Mbps and the downstream data rate of 2488.32 Mbps, 1244.16 Mbps, 622.08 Mbps, and 155.52 Mbps. It takes 8-bit, 16-bit, or 32-bit input to accormodate different date rates. The last short code word is handled inside the codec according to the standard to make it easier for system integration. Resource usage and performance parameters are listed in Table 1 for the encoder and in Table 2 for the decoder.
