摘要： A method, an apparatus and a system for realizing elongation of data transmission in a passive optical network are disclosed by this invention. Between the BCDR module and E/O amplifying module, the said apparatus comprises a delimiter matching module and a buffering preamble compensation module. The delimiter matching module receives a data frame transmitted from the said BCDR module and determines the position of the delimiter in the data frame; the said data frame is O/E converted, amplified and reshaped by an O/E amplifying module and then its clock and data are recovered by the BCDR module. The buffering preamble compensation module receives and buffers the data frame output from the delimiter matching module, inserts a preamble for compensation into the data frame according to the position of the delimiter in the data frame determined by the said delimiter matching module and then transmits the said data frame to the said E/O amplifying module according to downstream retiming clock. Embodiments of this invention realize elongation of data transmission by an electric regenerator OEO.

The information transfer method includes: determining an indicator of a start bit in a protection time slot or a preamble time slot of a laser, and establishing a communication channel according to the indicator of the start bit; inserting Operation Administration and Maintenance (OAM) information of a Long Reach-Passive Optical Network (LR-PON) device into an upstream frame sent to an Optical Line Terminal (OLT) device by the LR-PON device at a position indicated by the indicator of the start bit, and transporting the upstream frame to the OLT device through the communication channel. Therefore, OAM functions of the LR-PON device are extended, so that the OAM information can be transported by the LR-PON device independently, and OAM characteristics of the LR-PON device are enhanced. For example, PON protection is better supported, and the speed and success ratio of protection switching of a PON system are increased.
