Abstract

The invention relates to the optical communication field, and discloses optical network equipment to solve the technical problems in the prior art that the optical network equipment fails to work if an optical module fails; the optical network equipment comprises the following structures: a first processor; a first transmission interface arranged in the first processor; a first optical module connected with the first processor through the first transmission interface, and the first processor communicates with the first optical module through the first transmission interface; a second optical module connected with the first processor. The first processor is used for controlling the second optical module to close when the first optical module is in a working state, and controlling the second optical module to work when the first optical module fails. Even partial optical module fails, the optical network equipment of the invention can keep a normal working state.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical network device. Background technique [0002] Passive Optical Network (GPON) refers to the optical distribution network (ODN) between OLT and ONU, without any active electronic equipment, it is a pure media network, which avoids the electromagnetic interference and The impact of lightning reduces the failure rate of lines and external equipment, improves the reliability of the system, and saves maintenance costs at the same time. At present, the passive optical network is mainly IP-based GEPON, which supports the asymmetric transmission rate of up to 2.488Gbit / s downlink and 1.244Gbit / s uplink, the maximum physical distance is 20km, and the optical splitting ratio is between 16-128. [0003] Passive optical network mainly includes OLT (Optical Line Terminal), ONU (Optical Network Equipment: Optical Network Unit)\ONT (Optical Network Terminal: Optical Network Termi...
