Optical network and wireless network converged communication gateway and using method thereof

Abstract

An optical network and wireless network converged communication gateway comprises a wireless signal receiver, a wavelength division multiplexing add-drop multiplexer, an optical signal receiver, a signal mixer and an optical signal transmitter which are arranged in an electric shielding shell, wherein the electric shielding shell is used for forming an antenna of the wireless signal receiver. A wireless network data signal can be compounded under the condition of considering signal transmission in the power optical cable. The using method comprises the following steps of: connecting at least two groups of optical network and wireless network converged communication gateways in series on the same wavelength division multiplexing optical fiber, wherein the optical signal of the first wavelength domain is used for encoding long message information, the optical signal of the second wavelength domain is used for encoding short message information, the wavelength division multiplexing add-drop multiplexer is used for leading out an optical signal of which the wavelength belongs to the second wavelength domain through the optical signal of which the wavelength belongs to a first wavelength domain; and the optical signal transmitter correspondingly codes whether the wavelength of the second optical signal belongs to the first wavelength domain or the second wavelength domain accordingto the fact that a third electric signal belongs to the long message information or the short message information.

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 use method thereof. Background technique [0002] Optical fiber communication is a communication method that uses light waves as the carrier and optical fiber as the transmission medium to transmit information from one place to another. Optical fiber communication is far superior to cable and microwave communication in the following aspects: wide transmission frequency, high anti-interference and low signal attenuation. [0003] The power optical cable is mainly used as a wire, and its interior is compounded with an optical fiber propagation medium to facilitate signal transmission. At present, power optical cables are divided into four types: all-dielectric self-supporting optical cables (ADSS optical cables), optical fiber composite overhead ground wires (OPGW optical cables), optical fiber composite p...
