Description

System for optic dispersion repeater

The present invention relates to an optical dispersion repeater system for relaying wireless communication, and more particularly, to improve the scalability of a relay remote unit, which is a relay service terminal through digital combining of communication signals, and to provide various communication services through a channel having a large communication bandwidth. It relates to a light scattering repeater system for relaying.

The conventional optical repeater is composed of a relay main unit which is installed in close proximity to the base station and a relay remote unit which is located far away from the base station by a predetermined distance or more. The relay main unit converts the radio signal into an optical signal and transmits the radio signal to the relay remote unit in order to transmit an RF signal coupled to a radio transceiver that outputs a radio signal from the base station at a long distance. The relay main unit and the relay remote unit are connected by optical cables, which are physical channels for transmitting and receiving optical signals, and the relay remote unit is installed in a shaded area, an area not covered by the base station, to shade the radio signal coupled by the relay main unit at the base station. Relay to the area.

The relay main unit couples the radio signal of the base station and transmits the coupled radio signal to the RF divider, an RF divider for dividing the radio signal of the RF interface, and converts the divided radio signal into an optical signal and relays it. And a wavelength division multiplexer for converting the optical signal transmitted from the remote unit into a wireless signal. The wavelength division multiplexer includes an electrical / optical converter for converting a wireless signal into an optical signal and an optical / electrical converter for converting an optical signal into a wireless signal. The relay remote unit includes a wavelength division multiplexer for interfacing the relay main unit with an optical signal, and an RF interface for interfacing the antenna with the wavelength division multiplexer.

Further, another conventional optical repeater is composed of a relay main unit, a hub unit and a relay remote unit. When the distance between the base station and the shadow area is far, a hub unit is formed between the relay main unit and the relay remote unit to increase the connection distance between the relay main unit and the relay remote unit. The relay main unit and the hub unit are connected by an optical cable, which is a physical channel using wavelength division multiplexing (WDM), and the hub unit and the relay remote unit are also connected by an optical cable.

However, the conventional repeater system converts one communication signal input to the relay main unit from the IF signal to the optical signal, optically transmits the optical signal transmitted to the relay remote unit through the hub unit, and converts the optical signal transmitted to the relay remote unit into an RF signal. Later, while transmitting to the outside wirelessly, the RF signal wirelessly received by the relay remote unit is converted into an optical signal and optically transmitted to the relay main unit through the hub unit, and the optical signal transmitted to the relay main unit is restored to the IF signal and then the IF signal. Alternatively, since the analog signal transmission method outputs to the outside in the form of a digital signal, there is a limit in reducing the transmission loss.
