An ROF link system comprises ROF transmitting blocks(31-1-31-N) and ROF receiving blocks(38-1-38-N). Each of the ROF transmitting blocks(31-1-31-N) comprises a Seep OSC(Oscillator)(301-1-301-N), a multiplier(302-1-302-N), and a BPF(Band Pass Filter)(303-1-303-N). The Seep OSCs(301-1-301-N) receive information on an IF band established through the first control part(33) and provide frequency components of the IF band for IF modulation respectively. The multipliers(302-1-302-N) respectively combine input service signals(1-N) with the IF frequency components of the Seep OSCs(301-1-301-N) and execute IF modulation. The BPFs(303-1-303-N) execute filtering for the IF-modulated IF-band signals respectively. Each of the ROF receiving blocks(38-1-38-N) comprises a BPF(304-1-304-N), a Seep OSC(305-1-305-N), and a multiplier(306-1-306-N). The BPFs(304-1-304-N) respectively execute filtering for the IF-modulated IF-band signals transferred from the ROF transmitting blocks(31-1-31-N). The Seep OSCs(301-1-301-N) receive information on an IF band established through the second control part(37) and provide RF-IF frequency components for IF-to-RF modulation respectively. The multipliers(302-1-302-N) respectively combine the IF-band signals transferred through the BPFs(304-1-304-N) with RF-IF frequency components of the Seep OSCs(305-1-305-N) and execute RF modulation.

摘要： An integrated amplification unit and a remote unit of a mobile communication network optical repeater are provided to enhance efficiency by preventing a loss of signals that may be caused by a cable, and save the cost required for the cable by omitting an installation of the cable. A photoelectric transformation unit(210) transforms an inputted optical signal into an electrical signal. A primary amplifier(220) amplifies a signal transferred from the photoelectric transformation unit(210) with a high gain. A secondary amplifier(230) amplifies the signal which has been amplified by the primary amplifier(220) with a high power level and outputs it. An integrated amplificaiton unit(205) converts an optical signal inputted from a doner(300) into an electrical signal, amplifies it with a high gain and power, and outputs it. A controller(201) controls the integrated amplifying unit(205). A filter(240) filters a spurious signal of the signal which has been outputted from the integrated amplification unit(205) and outputs it.
