Embodiment 1

[0068] In this embodiment, the network structure of the present invention is as image 3 As shown, in this system, the home wiring is a PON structure, which is more flexible and easy to expand. It can realize one-to-many data transmission in the home network, and for the signal interaction between the edge ONU and the central office OLT, there is no need for PON and ETH Conversion, reducing delay and jitter, improving signal quality.

[0069] Among them, see Figure 4 , the home all-optical network system includes a central office OLT, an FTTR optical gateway and a plurality of edge ONUs. The FTTR optical gateway includes: a first ONU standard optical interface, an OLT short-distance optical interface, a PON ONU MAC and a processing unit; the PON ONU MAC is connected to the processing unit, and the processing unit is respectively connected to the first ONU The standard optical interface is connected to the OLT short-distance optical interface, the first ONU standard optical ...

Embodiment 2

[0111] Referring to the figure, this embodiment provides an implementation method of a home all-optical network system, which specifically includes the following steps:

[0112] Step 101: The PON ONU MAC receives the downlink PON signal of the central office OLT, extracts the burst control information from the downlink PON signal, determines the local burst transmission time slice according to the burst control information, and sends the burst control information sent to the processing unit.

[0113] In this embodiment, the internal ONU and the edge ONU in the FTTR optical gateway are first activated according to the provisions of ITU-G.984.3, wherein the activation process includes a synchronization phase, a serial number acquisition phase and a ranging phase. In the synchronization phase, the ONU that is still in the inactive state will initiate a local downlink synchronization, and synchronize through the downlink PHY frame. In the sequence number acquisition phase, the ON...

Abstract

The invention discloses a household all-optical network system and an implementation method thereof. The household all-optical network system comprises a local side OLT, an FTTR optical gateway and a plurality of edge ONUs. The FTTR optical gateway comprises a first ONU standard optical interface, an OLT short-distance optical interface, a PON ONU MAC and a processing unit. The PON ONU MAC is connected with the processing unit, the processing unit is respectively connected with the first ONU standard optical interface and the OLT short-distance optical interface, the first ONU standard optical interface is connected with the local side OLT, and the OLT short-distance optical interface is connected with each edge ONU. According to the invention, the home wiring is of a PON structure, is relatively flexible and easy to expand, can realize one-to-many data transmission in a home network, does not need PON and ETH conversion for signal interaction between an edge ONU and a local side OLT, reduces time delay and jitter, and improves signal quality.

Description

technical field [0001] The invention belongs to the technical field of communication, and more specifically relates to a home all-optical network system and an implementation method thereof. Background technique [0002] The communication industry has been continuously accelerating the upgrade of optical fiber bandwidth. Currently, most of the access network has achieved optical fiber access. China's fiber optic broadband development maintains a leading position in the world. According to relevant data released by the State Internet Information Office, as of the end of December 2019, the number of Internet broadband access ports in the country reached 916 million, of which fiber access ports accounted for 91.3%. much higher than the global average. At the same time, innovative business applications are also emerging in an endless stream. Ultra-high-definition video, cloud VR (Virtual Reality, virtual reality), cloud games, online education, remote office, etc. have raised m...
