    摘要: In the field of optical network communication technologies, a method, a device, and a system for transmitting a constant rate data stream are provided. The method for transmitting the constant rate data stream by the first network device includes: receiving a constant rate data stream; calculating an input rate of the constant rate data stream or a rate difference between the input rate and a standard rate of the constant rate data stream in each cycle of a reference clock; encapsulating the constant rate data stream into a Gigabit-Passive Optical Network (GPON) Encapsulation Method (GEM) frame by using a bit as a minimum encapsulation unit; and encapsulating the GEM frame into a GPON Transmission Convergence Layer (GTC) frame, and sending the GTC frame to the second network device through a GPON network. Therefore, the technical solutions may be widely applied to the GPON network.

    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.
