ABSTRACT:
There are provided an optical line terminal and an optical network terminal, which can process with the same forward error correction code even if an EFC frame size of G-PON descending signals is different between two types of 255 and 120. The optical network terminal includes a photoelectric converter, a PON transceiver, and a physical layer. The PON transceiver includes an error correction code encoder including a shortening compensation parameter table and a shortening compensation calculator for calculating compensated data by referring to the shortening compensation parameter table. Also the optical line terminal includes a photoelectric converter, a PON transceiver, and a physical layer. The optical line terminal includes an error correction code encoder including a shortening compensation parameter table and a shortening compensation calculator for calculating compensated data by referring to the shortening compensation parameter table.
