We present a comparative study of different FiberWireless networks with regards to their applications, architecture, hardware complexity, development costs, offered services and allocated bandwidths. While spectral resources and high data-rates are incessantly requested, these Radio over Fiber (RoF) networks have been proposed to overcome limitation in bandwidth. They take advantage of the spectral potential of millimeter-waves bands. Due to their flexibility, RoF links may be designed for a transparent transport of analog or digital signals. Several applications, based on point to point or point to multi points links, are here reviewed. Trends and prospects for these networks are also explored.

A radio-on-hybrid wavelength-division-multiplexing (WDM) transport system employing mutually injection-locked Fabry-Perot laser diodes (F-P LDs) is proposed and demonstrated. System performances evaluated by carrier to noise ratio (CNR), composite second order (CSO), composite triple beat (CTB), bit error rate (BER) for simultaneous transmission of CATV/LAN/ITS are improved. Our proposed systems are relatively simple and potentially low cost due to the use of mutually injection-locked F-P LDs as broadband light source (BLS). OCIS codes: (060, 2330), (060, 2360) INTRODUCTIONRadio-on-fiber (ROF) has many advantages in the field of fiber optics and wireless radio communication systems. It has provided a promising technique in broadband services such as local area network (LAN) and intelligent transport system (ITS) due to its large bandwidth and low attenuation [1]. Hybrid wavelength-division-multiplexing (WDM) transport systems are very useful in OC-48/OC-192, M-ary quadrature amplitude modulation (M-QAM), and CATV [2]. ROF and hybrid WDM were linked together to build up a radio-on-hybrid WDM transport system which can interoperate with broadband ROF distribution networks [3]. Such a system has multiple number of distributed feedback laser diodes (DFB LDs) which are wavelength selected for each channel and controlled to operate at a specific wavelength, this process will increase the cost and complexity of system. As the number of WDM channels increase, both reducing the cost of light sources and controlling the wavelength of all channels are required. Fabry-Perot (F-P) LDs light sources are proposed for cost-effective solution to reduce the installation and management cost [4]. In this paper, a four-wavelength radio-on-hybrid WDM transport system based on mutually injection-locked F-P LDs is proposed and demonstrated. Two wavelengths are employed for CATV channels transmission, one wavelength is employed for 2.4GHz/LAN signal transmission, and one wavelength is employed for 5.8GHz/ITS signal transmission. The characteristic of this proposed system is the use of mutually injection-locked F-P LDs [5], which are relatively simple and cost-effective compared with other demonstrated scheme. F-P LDs have been used as broadband light source (BLS) with fifteen modes (1532-1544 nm) and with a flatness of <4 dB. System performances were studied over an 80-km standard single-mode fiber (SMF) transport. Good performances of carrier to noise ratio (CNR), composite second order (CSO), composite triple beat (CTB) for CATV signal; bit error rate (BER) values for 2.4GHz/LAN and 5.8GHz/ITS signals were obtained in our proposed systems.
