Abstract

The invention discloses a protection device of an Ethernet passive optical network (EPON) system and a data redundancy backup method and a monitoring method. A data redundancy backup device comprises an optical line terminal (OLT) downlink data processing module, an optical network unit (ONU) downlink data de-encapsulation module, an ONU uplink data processing module and an OLT uplink data de-encapsulation module, the protection device of the EPON system is also provided with a monitoring module, and the data redundancy backup method and the monitoring method are realized through the monitoring module. One optical-fiber full-protection device and one data redundancy backup device are added on an OLT device and an ONU device, so that the hand-in-hand optical-fiber full-protection in the EPON system can be realized, the zero-millisecond master and slave switching of the optical fiber can be realized, the zero business interruption is realized, redundant data backup is also provided, and the monitoring module can detect failure of a media access control (MAC) chip and other circuits; and the maintainability of the system is greatly improved. The high-reliability application places in the application fields such as military communication, industrial real-time control, security protection, and video monitoring can be satisfied.

Description

technical field [0001] The invention relates to a protection device of an EPON system in the communication technology, in particular to an all-fiber protection device of the EPON system, a data redundancy backup method and a monitoring method. Background technique [0002] The composition, data transmission and application of EPON system: [0003] EPON system and Ethernet passive optical network are a new type of optical fiber access network technology. It adopts point-to-multipoint structure and passive optical fiber transmission to provide multiple service transmissions on Ethernet. A typical EPON system consists of OLT equipment, ONU equipment and POS equipment. The OLT device (Optical Line Terminal) is placed in the central computer room, the ONU device (Optical Network Unit) is placed near the user equipment end, and the POS device (Passive Optical Splitter) is a passive optical splitter, which is a passive device that connects the OLT device and the ONU device. Devic...
