We propose a hybrid optical access network integrating FTTH and RoF systems sharing a single distributed infrastructure. After transmission over 50km optical fiber, power penalties of baseband and RF signals are less than 0.2dB. (C) 2007 Optical Society of America

Hybrid optical access networks, integrating fiber-to-the-home (FTTH) and radio-over-fiber (RoF) systems that share a single distributed infrastructure, are promising for future multiservice access networks. The primary concern is to enable RoF and FTTH systems to transmit both radio-frequency (RF) and baseband (BB) signals on a single wavelength over a single fiber. This study experimentally demonstrates simultaneous generation and transmission of a wired-line BB signal and a wireless RF signal on a single wavelength, using one external modulator. The hybrid signals transmitted over standard single-mode fiber (SSMF) do not suffer from periodic performance fading due to fiber dispersion. Following transmission over 50-km SSMF, the power penalties of both RF and BB signals are less than 0.2 dB.

We propose and experimentally demonstrate a simple simultaneous generation of baseband and RF signal based on double-sideband with optical carrier suppression (DSBCS). The relation between the RF driving level (VP-P/2V pi) for dual-electrode MZM and the receiver sensitivity are studied. Based on the optimal RF driving level of 0.43, only one single-electrode MZM is needed to generate the microwave using DSBCS scheme. After the microwave based on DSBCS scheme using only one single-electrode MZM is transmitted over 100km of SSMF, no penalty for the baseband and down-converted signals of the receiver sensitivity is observed.

We experimentally demonstrate a simultaneous generation of baseband (BB) and RF signals, using only one single-electrode Mach-Zehnder modulator (SD-MZM) based on double-sideband with optical carrier suppression (DSBCS) scheme. With optimal modulation index (MI = Vp-p/2V(pi)) equal to 0.43 for driving MZM, the receiver sensitivity of the RF signal can have 1-dB improvement. Based on this result, only one SD-MZM is needed to generate optical microwaves using DSBCS scheme, thus eliminating the requirement of a high-cost dual-electrode MZM without degrading the signal performance. Following 75-km standard single-mode fiber, the power penalties of both BB and RF signals are less than 0.3 dB.
