    摘要: In a service signal processing method, an optical network unit (ONU) receives a service signal; maps the service signal to a flexible optical service unit frame; and sends a first passive optical network transmission convergence frame to an optical line terminal (OLT), where the flexible optical service unit frame is encapsulated in the first passive optical network transmission convergence frame, and where the flexible optical service unit frame is used to carry the service signal in a passive optical network (PON) and an optical transport network (OTN). In this application, the flexible optical service unit frame can be transmitted in both the PON and the OTN, and the ONU and the OLT do not need to parse the service signal.

    摘要: This application discloses a service data processing method and device. A transmit-end device may generate an optical transport network (OTN) encapsulated signal carrying service data, and generate at least n FlexO (flexible optical transport network) frames based on the OTN encapsulated signal and send the at least n FlexO frames, where r FlexO frames in the at least n FlexO frames carry service check data, and the service check data may be used to restore the service data when bit error rates of k FlexO frames are greater than a reference bit error rate. In this way, if no more than r physical ports included in a FlexO group interface fail, or a bit error rate of no more than r FlexO frames is greater than the reference bit error rate due to another reason, a receive-end device may restore the service data through a received FlexO frame.

    摘要: Embodiments of the present invention disclose a method for generic mapping procedure (GMP) mapping, which includes: first the information about a adjusted time slot to be occupied by a second GMP block container is carried in the GMP overhead of a first GMP block container; then, the size of the second GMP block container is adjusted in accordance with the inforamtion; eventually, a client signal is mapped into the adjusted second GMP block container adopting a GMP scheme. This GMP mapping method, when working with a corresponding demapping method, provides lossless mapping and demapping of client signals during the process of bandwidth adjusting.

    摘要: A method and an apparatus for transmission using an interface, and a device. The method includes: obtaining a byte block stream, where byte blocks in the byte block stream are of a predetermined byte length; mapping the byte block stream to corresponding timeslots, where each timeslot corresponds to one byte block; distributing the byte block stream mapped to the timeslots; processing the distributed byte block stream based on an interface type configured for a physical interface; and sending the processed byte block stream. In the embodiments, data is transmitted based on a byte block distribution mechanism, to support different interface types, and a coupling relationship between service adaptation and a physical layer is decoupled, so that evolution and extension of transmission interface types do not affect a service adaptation procedure, thereby simplifying a transmission system.

    摘要: This application provides a data transmission method in an optical network and an optical network device. The method includes: obtaining, by a first device, first synchronization information from a first service data stream, and determining a to-be-transmitted service data stream; generating second synchronization information based on the first synchronization information; mapping the second synchronization information and the to-be-transmitted service data stream to an optical carrier container; and sending the optical carrier container. A second device receives the optical carrier container; obtains a second service data stream and third synchronization information from the optical carrier container through demapping; generates fourth synchronization information based on the third synchronization information; and inserts the fourth synchronization information into the second service data stream, to obtain a third service data stream. In this way, time synchronization precision is improved.
