Abstract:
The present disclosure relates to an optical repeater system for 5th generation (5G) mobile communication. The optical repeater system does not require an additional optical wavelength for a plurality of remote units and can increase the transmission capacity by adding a remote unit without incurring an unnecessary cost, thereby facilitating high-speed and large-capacity data transmission. In addition, the optical repeater system can transmit/receive both a high-speed and large-capacity service signal, as an analog optical signal, and a management control signal, as a digital optical signal, between a master unit and a plurality of remote units. Also, the optical repeater system can selectively and differently compensate for propagation delay times of multiple paths between a terminal and a base station in a mobile communication system, especially, in the 5G mobile communication system.

Claim (Index 8):
An optical repeater system comprising:\n a master unit connected to a base station; a plurality of remote units connected to the master unit in a cascade configuration; and an optical delay control device, wherein the plurality of remote units include a first remote unit directly connected to the master unit by an optical cable and a second remote unit directly connected to the first remote unit by another optical cable, wherein the master unit is configured to:\n receive a downlink electric signal from the base station, \n convert the received downlink electric signal into a downlink optical signal of a first wavelength, \n transmit the converted downlink optical signal to the plurality of remote units through the first remote unit, \n receive an uplink optical signal of a second wavelength from the plurality of remote units through the first remote unit, \n convert the received uplink optical signal into an uplink electric signal, and \n output the converted uplink electric signal to the base station, and \n wherein each of the remote units is configured to: \n receive the downlink optical signal from the master unit or a previous remote unit connected thereto, \n divide the received downlink optical signal into first and second downlink electric signals, \n output the first downlink electric signal to an antenna, \n transmit the second downlink electric signal to a subsequent remote unit connected thereto, \n receive a first uplink electric signal from the antenna, \n receive an uplink optical signal from the subsequent remote unit, \n convert the received uplink optical signal into a second uplink electric signal, \n combine the first and second uplink electric signals, \n convert the combined uplink electric signal into the uplink optical signal, and \n transmit the converted uplink optical signal to the master unit or the previous remote unit, \n wherein the plurality of remote units include a subset of remote units which are directly connected to the base station, are disposed in a parallel configuration, and form multiple paths with the master unit, and wherein the optical delay control device is provided on the multiple paths, includes a plurality of cable members having different lengths on each of the multiple paths, and is configured to compensate for a propagation delay time of each path by selectively connecting the plurality of cable members to each path.
