摘要

PURPOSE: Method and apparatus for recovering burst mode clock and data are provided to extract clock from fast burst mode packet data transmitted from ONUs to OLTs. CONSTITUTION: An apparatus for recovering burst mode clock and data comprises the following: a receiving unit(510) receiving optical signals including packet data from plural ONUs(optical network units); a power restoration unit(520) restoring the optical signals to electric signals; and a data insertion unit(530) inserting dummy data into a temporal section without the packet data on the electric signals.
