Abstract: A remote access unit having plural antennas and a bidirectional optical wireless network are provided to separately amplify time-division channels and frequency-division channels, respectively, and to combine or transmit the channels, thereby suppressing the generation of non-linear phenomena of an active element caused by leakage of downlink signals. The first and second antennas(330,340) wirelessly transmit downlink data, and input wirelessly received uplink data to the inside of a remote access unit(300). A duplexer(320) inputs downlink frequency-division channels among the downlink data to output the inputted channels to the first antenna(330), and inputs the uplink data to output uplink frequency-division channels. A circulator(350) outputs the divided downlink time-division channels and broadcasting channels to the second antenna(340), and outputs the uplink time-division channels to a switch(360). The switch(360) inputs the uplink time-division channels from the circulator(350). A controller(390) controls the switch(360) in order to prevent the downlink time-division channels, the broadcasting channels, and the uplink time-division channels from being overlapped together.

The third port of the second coupler(240) and one end of an O/E(Optical-to-Electric) converter(250) are connected with optical fibers(260,265). The first coupler(290) separates the first downstream signal of the first duplexing method inputted through third port of the second coupler(240) and the second downstream signal of the second duplexing method. The circulator(310) outputs the first downstream signal inputted from the first coupler(290) to its second port and outputs the first upstream signal of the first duplexing method to one end of the O/E converter(250). The second coupler(292) outputs the second downstream signal inputted from the first coupler(290) to its second port, and outputs the second upstream signal of the second duplexing method to one end of the O/E converter(250).

If the number of 1 is odd-numbered, a toggle unit toggles output signals of the decider. An output unit determines output values of the rest channels according to the data input signals. An optical duobinary transmitter comprises as follows. A precoder(100) codes the data input signals in N channel unit through a parallel processing function.

Abstract: PURPOSE: A duo-binary optical transmission device using an SOA(Semiconductor Optical Amplifier) is provided to realize crossed phase properties of duo-binary signals by using an SOA and an optical band pass filter without using an electric low band pass filter, thereby overcoming restrictions on transmission quality while realizing high speed and high density. CONSTITUTION: A duo-binary optical transmission device(100) comprises as follows. A light source(101) outputs a carrier. A signal generator(102) generates an NRZ(Non Return to Zero) data signal. A coding device(103) codes the NRZ data signal. An interference-type SOA(110) modulates a phase of the optical carrier by a gain change in accordance with a bias current applied in combination with the coded signal. An optical band pass filter(105) receives the phase-modulated optical signal to filter the signal according to a determined band, and outputs a duo-binary optical signal. A driving amplifier(104) amplifies the coded signal to output the amplified signal.
