Abstract

The invention discloses a method and device for processing the working parameters of a passive optical network (PON) system. The method comprises the following steps: acquiring the distances of all optical network units (ONU) under a PON port; determining the working parameters according to the maximum difference distance supported by the system as well as the maximum distance and the minimum distance in the acquired distance; and when the maximum distance and the minimum distance acquired in the acquiring step are changed and the working parameters need to be regulated, determining the working parameters again in the determining step. Through the invention, the working parameters in the PON can be automatically regulated.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for processing working parameters of a passive optical network system (or simply referred to as a passive optical network). Background technique [0002] In the current passive optical network technology, the maximum logical distance, the maximum physical distance and the optical fiber differential distance are defined in the International Telecommunications Union (International Telecommunications Union, referred to as ITU) standards G.984 and G.987. [0003] Logical reach refers to the maximum distance between an Optical Network Unit (ONU for short) and an Optical Line Terminal (OLT for short). For example, without considering the limitations on the physical layer, the maximum distance in the GPON / XG-PON system is 60KM. [0004] Physical reach (Physical reach) refers to the maximum physical distance between the ONU and the OLT, usually not less than the op...
