Embodiment Construction

[0021] The content that needs to be further limited to the indoor optical router network wireless optical communication device of the present invention is as follows.

[0022] About Optical Router:

[0023] The wavelength selection switch in the optical router 1 is a liquid crystal wavelength selection switch. There are 8 ports in total, of which 2 ports are respectively connected to the input single-mode fiber and the output single-mode fiber, and the remaining 6 ports are respectively connected to a maximum of 6 adjacent optical routers. 1 is connected to the port of the wavelength selective switch.

[0024] If the indoor area is large and you do not want to increase the number of optical routers 1, the distance between the optical routers 1 in the optical router network is relatively large. Erbium fiber amplifiers amplify the power of optical signals. The optical router 1 at this time amplifies the signal while retransmitting the signal.

Abstract

The invention discloses an indoor overhead optical router network wireless optical communication device and method, and belongs to the technical field of wireless optical communication. In the prior art, communication efficiency and system redundancy are low. In the communication device, an optical router network is composed of a plurality of optical routers distributed at the centers and vertexesof a plurality of regular hexagons, and each optical router is a routing node of the optical router network; wherein the plurality of user sides and the optical routers are in a wireless optical communication relationship; according to the communication method, the communication device is adopted to achieve communication, an optical router network in the communication device is installed at the indoor top, on one hand, a certain optical router in the optical router network is connected with an optical line terminal, and then the optical line terminal is connected with an external network through a home-entry optical fiber; on the other hand, each indoor user is connected with one user side; and then optical communication is completed according to five steps of client registration, route switching and logout, communication path self-organization, communication path self-healing and data transmission.

Description

technical field [0001] The invention relates to a wireless optical communication device and method for an indoor overhead optical router network, and belongs to the technical field of wireless optical communication. Background technique [0002] Wireless optical communication technology uses light waves as signal carriers to realize communication. Since the frequency of light waves is much higher than that of radio waves, wireless optical communication has the advantages of high transmission rate, large communication capacity, anti-electromagnetic interference, and no radiation, and is widely used. Indoor wireless optical communication is the main application field of wireless optical communication technology. Compared with the currently commonly used wireless local area network (WIFI), the indoor wireless optical communication speed can reach the order of gigabits per second, and it also takes into account high security, which is exclusive to multiple users. bandwidth.
