In this paper theoretical model of multi-band modulation in WDM PON system is proposed. Multi-band modulation helps to reduce the infrastructure cost without much effect on base-band signal being transmitted. Theoretical explanation of multi-band modulation is investigated. A simple model is used to investigate further impact of IF signal, which is digitally modulated in different formats, used in the multi-band modulation technique. The proposed system can satisfy the requirements of fiber-to-the-home (FTTH) by realizing that a transmission of 25KM long distance is possible. The impact has been studied by using eye-diagram obtained and the theoretical explanations. The proposed work shows that the baseband signal is not much affected by the IF digitally modulated signal.

This work reports the implementation of the first cognitive broadband optical-wireless network published in literature, aimed to deal with the new demands for convergent future access networks. It simultaneously provides the functionalities of ultra-wideband radiofrequency spectrum sensing, dynamic resource allocation, and centralized processing capability, as well as the use of ultra-wideband antennas and radio over fiber technology. The performance of this innovative architecture has been evaluated in a geographically distributed optical-wireless network under real conditions. Experimental results demonstrate broadband and remote spectrum sensing from 680 MHz up to 8.0 GHz and an enhancement of more than 30 dB in the carrier to interference plus noise ratio (CINR) parameter, improving the cognitive user experience and enabling energy efficiency and flexibility in the use of the radiofrequency spectrum.

“…In [11], a wireline signal and an mmW signal are modulated on an optical carrier and two optical sidebands, respectively, at two different optical modulators and transmitted over different WDM channels. To lower the overall cost of the system, in [12] the wireless data and wireline data are modulated on a single optical sideband at a single optical modulator and transmitted over a WDM channel. Another un-modulated optical sideband is transmitted over another WDM channel to the BS to beat with the data modulated sideband for mmW generation.…”

A broadband millimeter-wave (mmW) at 60-GHz band and an impulse radio ultra-wideband (IR-UWB) over a colorless 100-GHz dense wavelength division multiplexing (DWDM) passive optical network (PON) that supports simultaneous transmission of a broadband mmW signal, a UWB signal and a wireline baseband signal is experimentally demonstrated. At the transmitter, a polarization modulator (PolM) is employed, which operates in conjunction with a polarization controller (PC) and a polarization beam splitter (PBS) as an equivalent Mach-Zehnder modulator (MZM). For 60-GHz and IR-UWB signal transmission, the equivalent MZM is biased at the minimum transmission point to generate two sidebands that are separated at a frequency in the 60-GHz band, and the wireless signals (60 GHz and IR-UWB) are carried by the two sidebands. For the wireline baseband transmission, the equivalent MZM is biased at the maximum transmission point to generate only the optical carrier, and the wireline signal is carried by the optical carrier. The wireline signal and the wireless signals are orthogonally polarized and sent over a single-mode fiber (SMF) to a base station (BS). For each WDM channel in the central station (CS) and the BS, since no optical filters are employed, colorless operation is supported. Point-to-point error-free transmission of a 1.25-Gbps mmW signal, a 1.25-Gbps IR-UWB signal and a 10-Gbps wireline signal over a 25-km SMF is experimentally demonstrated. The number of users that can be supported by the proposed colorless WDM-PON is estimated based on the measured receiver sensitivities. Index Terms-Colorless, passive optical networks (PON), radio over fiber (RoF), UWB over fiber (UWBoF), wavelength division multiplexing (WDM).
