    摘要: 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.

Between a burst-mode clock and data recovery (BCDR) module and an electrical-optical (E/O) amplification module, the device includes a delimiter matching module and a preamble buffering and compensating module. The delimiter matching module is adapted to receive a data frame sent by the BCDR module and determine a location of a delimiter in the data frame. An optical-electrical (O/E) amplification module performs O/E conversion, amplification, and shaping on the data frame. The BCDR module then performs clock and data recovery processing on the data frame. The preamble buffering and compensating module is adapted to receive and buffer the data frame output from the delimiter matching module, insert a compensation preamble in the data frame according to the location of the delimiter in the data frame determined by the delimiter matching module, and send the data frame to the E/O amplification module according to a retiming clock of a downstream direction. Therefore, the data transmission extension is realized in an optical-electrical-optical (OEO) manner.
