“…This technique can be applied to OFDM RF signals to reduce the intermodulation distortion, clipping noise, and impact of optical reflection, as well. The techniques from 3 to 7 solves the technical issue 4 on the millimeter RF signal transmission, with the use of optically beating-up and -down the RF carrier frequency [12], [13], the single sideband (SSB) or carrier suppress (CS) modulation [14], [15], optically filtering the SSB at the detector [16], generating many harmonics by FM modulation of LD [17] [18], and detecting the SSB with digital coherent detection [19], respectively. In the next section, we will describe the RoF access networks to apply the techniques 2 and 3 in Table 1.…”

This paper reviews optical coherent technologies in next generation access networks with the use of radio over fiber (RoF), which offer key enabling technologies of wired and wireless integrated and/or converged broadband access networks to accommodate rapidly widespread cloud computing services. We describe technical issues on conventional RoF based on subcarrier modulation (SCM) and their countermeasures. Two examples of RoF access networks with optical coherent technologies to solve the technical issues are introduced; a video distribution system with FM conversion and wired and wireless integrated wide-area access network with photonic up-and down-conversion.

“…The bias of MZM d was set to -4.3 V, at which it works as the optical double sideband modulation with suppressed carrier (DSB-SC). Next, the generated optical tones were frequency-demultiplexed by an arrayed waveguide grating (AWG) with the channel spacing of 25 GHz [7]. Then, only the longer-wavelength tone at c/(f cd -f RF )/2 was modulated by using another optical modulator (MZM a ) with a baseband signal.…”

“…Not only to overcome the fiber-dispersion effect but also to lessen high-cost RF-band electrical active devices as much as possible, we have proposed photonic downconversion and upconversion techniques [7]. In addition, an optical heterodyne technique is important to achieve the highly stable RF-band signal generation in RoF systems [8].…”

To overcome the scarcity of available radio frequency (RF) resource, ultra-wideband (UWB) attracts its attention as one of next generation high-speed radio communication technologies because UWB systems can share the RF band with existing conventional narrowband radio systems. If such UWB signal can be delivered through optical networks without distance limitation, various standalone UWB applications can be networked widely and become available anywhere on demand.In this paper, novel optical transmitter and receiver of millimeter-wave UWB signal are proposed with direct photonic conversion techniques. We experimentally demonstrate the optical detection and regeneration, after 3-m-long transmitted in the air, of the optically generated 24-GHz UWB with the bandwidth of 4 GHz at the data rate of 250 Mb/s.

“…However, Wavelength reusing technique combined with the optical double sideband with carrier (ODSBþC) modulation could also improve the system efficiency by wiping out the costs of light sources at BSs. Using arrayed wave guide gratings (AWGs) as passive components for signal routing, full-duplex signal distribution of dense wavelength division multiplexing (DWDM) RoF signals has experimentally been demonstrated and reported [10,11]. But in a multi-BS ROF system, signal routing between all of those BSs must be managed in a CO.…”

We propose a scheme to improve the transmission efficiency of radio over fiber system, which is to constitute a local area optical network with many micro cell base stations centering on the remote node. All the data switching among base stations within this optical network will be realized by the wavelength allocation module of the remote node instead of the central office. Such a method has the advantage of economize the capacity of the backbone fiber between the center office and the remote node, therefore increases the transmission efficiency of the system. © 2010 Wiley Periodicals, Inc.
