Abstract

Gomes, N.; Morant, M.; Alphones, A.; Cabon, B.; Mitchell, J.; Lethien, C.; Csörnyei, M.... (2009). Radio-over-fiber transport for the support of wireless broadband services. Journal of Optical Networking. 8(2):156-178. https://doi.Some of the work carried out within the EU Network of Excellence ISIS on radio over fiber systems for the support of current and emerging wireless networks is reviewed. Direct laser modulation and externally modulated links have been investigated, and demonstrations of single-mode fiber and multimode fiber systems are presented. The wireless networks studied range from PANs (such as ZigBee and UWB) through wireless LANs to wireless MANs (WiMAX) and third generation mobile communications systems. The performance of the radio over fiber transmission is referenced to the specifications of the relevant standard, protocol operation is verified and complete network demonstrations have been implemented.

Indoor coverage improvement of MB-OFDM UWB signals with radio over POF system

“…Previous studies have been already achieved on the UWB over fiber system but have been limited to one type of glass fiber (singlemode fiber [5] and multimode fiber [6,7]) and packet error ratio (PER) measurement. An EVM analysis regarding to the length of the used glass multimode fiber is reported in [8]. EVM values close to 14% is obtained for transmission over 300 m at 850 nm, values far off the results presented here with multimode plastic fibers.…”

Study of OFDM Technique on RoF Passive Optical Network

“…After that, to integrate the OFDM signal RF or to convert the OFDM signal to RF, a RF-IQ mixer is used [ -6]. The resulting signal is 4 combined with the light wave from the CW laser through an external modulator, Mach-Zehnder modulator [7][8][9]. The resulting signal from the modulator is transmitted over single mode optical fiber followed by a 1:2 optical splitter to make the use of the Passive Optical Network.…”

Performance Assessment of UWB-Over-Fiber and Applications

“…(GSM) [3], WiMAX [4] and ultra-wide band (UWB) [5,6]. Moreover, RoF systems also offer other attractive advantages such as low weight and immunity to electromagnetic interference.…”
