Abstract

The invention provides a lead code setting method and device. The method comprises that a first lead code length value which is needed when an optical module of an optical network unit (ONU) achieves stable illumination and a second lead code length value issued by an optical line terminal (OLT) are obtained; and when the first lead code length value is greater than the second lead code length value, the lead code length during registration of the ONU is adjusted the length corresponding to the first lead code length value. According to the technical scheme provided by the invention, the problem that failure of ONU registration caused by the lead code cannot be determined by proper schemes in the ONU registration process is solved; the optical module can achieve stability no matter the OLT requires a long packet or a short packet during intercommunication between different devices; and the ONU is activated and registered, and conflict between the optical module hardware of the ONU and the OLT during intercommunication is overcome.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a preamble setting method and device. Background technique

[0002] With the rapid development of the Internet and information technology, it has become an inevitable development trend for global telecom operators to vigorously develop optical networks. Among them, the passive optical access network (Gigabit-capablePassiveOpticalNetwork, referred to as GPON) is due to its high bandwidth, high efficiency, Many advantages such as wide-area coverage are favored by international mainstream operators. However, there has always been the problem of difficult interoperability of GPON equipment among different equipment manufacturers, which has plagued the development of GPON. The realization of interconnection is of great significance in saving costs, developing new services, and adapting to market competition. Therefore, operators regard the realization of interconnection as one of th...
