Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0057] In order to facilitate the understanding of the embodiments of the present application, the concepts of the nouns involved are firstly introduced below:

[0058] 1. PON is a passive optical network. It usually consists of three parts: OLT, ODN and ONT at the central office. Here, ONT can also be an optical network unit (ONU). like figure 1 As shown, multiple ONTs are connected to the PON port of the same OLT through the ODN.

[0059] 2. FTTR is to extend the optical fiber not only to the user's room, but also to each room of the user, and install wireless routing equipment inside the room. In this way, the distance between the user's terminal equipment and the wireless routing equipment is reduced, and the wireless signal...

Abstract

The invention provides a networking method and device of a passive optical network, and belongs to the technical field of optical fiber communication. The PON comprises a main ONT and at least one edge ONT, the at least one edge ONT comprises a first edge ONT, and the method comprises the following steps: the first edge ONT detects a networking mode with the main ONT, receives configuration content issued by the main ONT under the condition that the networking mode is detected to be the first networking mode, and configures the first edge ONT based on the configuration content. And under the condition that the networking mode is detected to be the second networking mode, the first edge ONT is configured as a bridging ONT of the main ONT or enters a sleep mode. According to the invention, the efficiency of PON networking can be improved.

Description

technical field [0001] The present application relates to the technical field of optical fiber communication, and in particular to a passive optical network (passive optical network, PON) networking method and device. Background technique [0002] PON is a passive optical network, which usually consists of three parts: an optical line terminal (OLT), an optical distribution network (ODN) and an optical network terminal (ONT) at the central office. When the PON is a secondary network, the secondary network includes the main ONT and the edge ONT, the main ONT is connected to the OLT, and the edge ONT is connected to the main ONT. For example, in a (fiber to the room, FTTR) networking, the home gateway is the master ONT, the ONTs deployed in each room are edge ONTs, and the home gateway manages the edge ONTs deployed in each room. [0003] In related technologies, the edge ONT is connected to the main ONT, and the edge ONT is manually configured as a wireless routing device. ...
