Embodiment Construction

[0021] In the following description, for the purpose of explaining and not limiting the present invention, specific details of specific structures, interfaces, techniques, etc. are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced in other embodiments than these specific embodiments.

[0022] The present invention provides a method of effectively using a frame exchange scheme for data transmission in a GE-PON system. Briefly, the present invention includes steps: the OLT sends a signal to the ONU through a control frame; the ONU responds to the signal and sends back a bandwidth request signal to the OLT according to the TDM scheme; the OLT performs scheduling processing and informs the ONU of the scheduling through a grant signal result; and a frame is sent by the ONU in response to the scheduling result.

Abstract

A method for transmitting uplink data in a gigabit Ethernet-passive optical network (GE-PON) system is disclosed. In this GE-PON system, it includes an optical fiber line terminal with a scheduler and an optical network unit connected to the optical fiber line terminal. When the first period begins, the optical fiber line terminal receives a bandwidth allocation request signal from the optical network unit. According to the The bandwidth allocation request signal allocates the transmission bandwidth to each optical network unit, and transmits the allocated transmission bandwidth to each optical network unit before the start of the second period following the first period.

Description

technical field [0001] The present invention relates to a Gigabit Ethernet-Passive Optical Network (hereinafter, referred to as "GE-PON), and more particularly, to a data transmission method used in a GE-PON structure. Background technique [0002] In order to construct the network from the telephone office to the building or the home, xDSL (x-Digital Subscriber Line), HFC (Hybrid Fiber Coaxial Cable), FTTB (Fiber To The Building), FTTC (Fiber Fiber) with different multi-channel solutions have been implemented to the roadside), and different network structures such as FTTH (Fiber to the Home). Among these various network structures, FTTx (x=B, C, H) can be classified into active FTTx configured by an active optical network (hereinafter referred to as "AON") structure, and can also be classified into Passive fiber optic network (hereinafter referred to as "PON") configuration in passive FTTx. The structure of passive FTTx is more popular because it has an economical, simple...
