Appatatus and method for relaying in gigabit passive optical network

Optical signal relay method of a hybrid relay in a Gigabit passive optical network is downstream WDM-PON OLT (Wavelength Division Multiplexing-Passive Optical Line Terminal) 1 primary serial electric signal and downlink corresponding to the light signal GPON OLT (Gigabit Passive Optical Network Optical Line Terminal) receiving the second serial electrical signal selecting one of the serial electrical signal of corresponding to the optical signals, modulating the downlink serial electrical signal to the down-GTC (GPON transmission Convergence) frame, an uplink transmission from the down-GTC frame extracting the control information, it converts the down-GTC frame to down-serial electrical signal, and the converted serial electric signal and transmits the converted optical signal to the optical transceiver from the GPON OLT. One also converting the by using the extracted control information, extracts the upstream burst optical signal, converts the burst optical signal extracted into a serial electric signal and then modulates the burst GTC frame, modulated burst GTC frame in a continuous GTC frame after it was converted back into a serial electric signal and sent to the optical signal of the selected OLT.
