Fiber Optic Repeater Having Frequency Shift Keying Modem of PCB Type in Optic Module

摘要

The invention PCB type to be mounted within the light module to the PCB to form a frequency shift keying modem frequency shift is related to the modulation modem in an optical repeater having an optical module. An optical repeater according to the present invention comprises a first frequency shift keying modem to the master repeater optical module formed on a printed circuit board (PCB),, remotely by converting the first data signal received from the base station to the first optical signal sent to the repeater, and receiving a second optical signal from the remote repeater to the master repeater to transmit to the base station is converted to a second data signal; And a printed circuit board and formed on the second frequency shift (PCB) having a modulation modem to a remote repeater optical module, converting the first optical signal received from the master repeater to a first data signal sent out through the antenna, antenna converting the second data signal received from the second optical signal to be sent to a remote repeater to the master repeater. Accordingly, the frequency shift provided by the optical module to form a modulation modem module to the PCB of the cost, reduce the system construction costs, a simplified system by reducing the complexity of the RF signal for transmission line can be constructed.
