ABSTRACTA unusual bidirectional low cost WDM‐PON‐ROF communication network architecture using optical sextuple frequency which is based on photoelectron coherent modulation through a Double‐Arm‐Mach‐Zehnder‐Modulator with a number of different wavelength characteristics is provided and analyzed theoretically. After transmitting more than 25 km in a standard single mode fiber, the clear eye‐diagram and good bit error rate are obtained for wireless signal, wired signal and upstream signal communication. In this communication network architecture, because of no laser source, the base‐station (BS) is not complicated, and because of the optical sextuple frequency signal, the ultra high frequency of the local oscillator is greatly reduced. Compared with recent schemes, the outlays of switching center and BS are greatly decreased. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2079–2083, 2015
