Problems solved by technology

The uplink and downlink bandwidth ratio of EPON system is 1:1, and GPON is 1:2, which is very different from the business model.
Even if its next-generation upgrade system 10GEPON and XGPON have a maximum ratio of 1:10, it cannot adapt to the model structure required by the business. Under such conditions, network construction is either seriously insufficient in downlink bandwidth or uplink. huge waste of bandwidth

Embodiment Construction

[0026] The invention discloses a bandwidth expansion system applied to a GEPON system, including system architecture, system equipment, and a service transmission method.

[0027] The invention provides a bandwidth expansion system based on the GEPON system, including the GEPON system and the bandwidth expansion channel, and the bandwidth expansion channel includes the central office intelligent distribution transmitter (DLT), the terminal intelligent distribution receiver (DNU), the optical fiber amplifier and the wavelength division Multiplexer; GEPON system includes central office (OLT), passive optical network (PON) and terminal (ONU); wherein,

[0028] The service signal is sent by the service platform, and the signal is sent to the central office intelligent distribution transmitter (DLT) through the transmission network such as the core network and the aggregation network. The GEPON system central office (OLT) is transmitted by the GEPON system; the other part of the da...

Abstract

The invention discloses a bandwidth expansion system based on a GEPON system. A bandwidth expansion channel is composed of a local intelligent shunt transmitter (DLT) and a terminal intelligent shuntreceiver (DNU), and the GEPON system comprises a local side OLT and a terminal ONU. According to the bandwidth expansion scheme of the GEPON system, a downlink broadcast channel is seamlessly superposed on the basis of the existing GEPON system, so the downlink bandwidth is effectively increased. And the requirements of large-capacity access services in the future are met.

Description

technical field [0001] The invention relates to the field of optical access networks, in particular to a bandwidth expansion system. Background technique [0002] Nowadays, with the development of networks and services, especially with the rise of 4K and 8K video programs, people's demand for bandwidth is increasing. The bandwidth of traditional optical fiber network EPON and GPON systems can hardly meet the development of 4K and 8K services. At present, whether it is a new network or a network transformation, bandwidth is basically listed as the first technical index. How to obtain a large amount of bandwidth at a lower cost has become one of the key issues that operators have been considering. [0003] The future broadband access business model can be summed up as an asymmetric business model with the following behaviors as the main factor. The bandwidth required for downlink is a hundred times, thousand times or even higher than that for uplink (that is, the ratio is more...
