Embodiment Construction

[0046] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0047] see figure 2 , figure 2 It is a possible PON network structure diagram in the prior art. Such as figure 2 As shown, the OLT equipment is no longer deployed in the central computer room, but is deployed closer to the ONT, ONU and other equipment. in, figure 2 The PON network shown can include more OLTs, enabling more users in remote areas to access broadband services.

[0048] figure 2 Although the PON network shown can enable remote areas to access broadband services, the connection between the network side equipment and the OLT is through an Ethernet interface, and the main transmission media are network cables, optical fibers, etc. Therefore, a separate transmission medium needs to be deployed between each OLT device and the network side device. Since there are...

Abstract

The invention discloses a communication network and related equipment, the communication network comprises a first optical line terminal, a second optical line terminal and user side equipment, and the second optical line terminal can be connected with the first optical line terminal at the upper layer through a PON interface and can also be connected with the user side equipment at the lower layer through the PON interface. According to the communication network provided by the invention, users in remote areas can access the broadband service, and in addition, due to the point-to-multipoint transmission characteristic of the PON interface, the transmission medium can be saved, and the networking cost is reduced.

Description

technical field [0001] The present application relates to the technical field of optical communication, in particular to a communication network and related equipment. Background technique [0002] Current broadband access technologies are mainly divided into copper wire access technologies (such as various DSL technologies) and optical access technologies. An access network implemented by an optical access technology is called an optical access network (OAN). [0003] Passive optical network (PON) is an implementation technology of optical access network. PON is an optical access technology for point-to-multipoint transmission. The system architecture of PON is as follows: figure 1 shown. [0004] figure 1 Among them, the optical line terminal (OLT) is used to provide the network side interface for the OAN, the OLT is connected to the upper network side equipment (such as switches, routers, etc.), and the lower layer is connected to one or more optical distribution netwo...
