Optical network wireless network converged communication gateway and using method thereof

Abstract

An optical network wireless network fusion communication gateway includes: a wireless signal receiver, a wavelength division multiplexing add / drop multiplexer, an optical signal receiver, a signal mixer and an optical signal transmitter arranged in an electric shielding shell, and the electric shielding shell Antennas used to form wireless signal receivers. It can composite wireless network data signals under the condition of taking into account the signal transmission in the power optical cable. Its use method is that at least two groups of optical network wireless network fusion communication gateways are connected in series on the same wavelength division multiplexing fiber; the optical signal in the first wavelength domain is used to encode long message information, and the optical signal in the second wavelength domain is used for It is used to encode short message information; the wavelength division multiplexing add / drop multiplexer is used to pass the optical signal whose wavelength belongs to the first wavelength domain, and extract the optical signal whose wavelength belongs to the second wavelength domain; the optical signal transmitter is used according to the third electrical signal. The message information or the short message information corresponds to the wavelength of the encoded second optical signal belonging to the first wavelength domain or the second wavelength domain.

Description

technical field [0001] The invention relates to the technical field of gateways, in particular to an optical network and wireless network fusion communication gateway and a method for using the same. Background technique [0002] Optical fiber communication is a communication method in which light waves are used as carriers and optical fibers are used as transmission media to transmit information from one place to another. Optical fiber communication is far superior to cable and microwave communication in the following aspects: transmission frequency bandwidth, high anti-interference and low signal attenuation. [0003] The power optical cable is mainly used as a wire, and the optical fiber propagation medium is compounded inside it to facilitate the transmission of signals. At present, power optical cables are divided into four types: all-dielectric self-supporting optical cable (ADSS optical cable), optical fiber composite overhead ground wire (OPGW optical cable), optica...
