Data Transmission Control Method, Passive Optical Network Equipment, Apparatus, and Passive Optical Network

摘要

A data transmission control method, passive optical network (PON) equipment and apparatus, and a PON are presented. The method includes obtaining, by first PON equipment, data transmission information between the first PON equipment and second PON equipment; determining a target line rate between the first PON equipment and the second PON equipment according to the data transmission information; and transmitting data on a line between the first PON equipment and the second PON equipment according to the target line rate. The equipment includes an obtaining unit, a determining unit, and a communications unit. In the embodiments of the present disclosure, energy consumption of an optical network unit (ONU) can be reduced when service traffic of the ONU is light.
