Simulative Investigation of Phase Noise effects in Radio over Fiber Networks based on Optical Single Side Band Transmission Technique
نویسندگان
چکیده
. Abstract Carrier to Noise Ratio (CNR) has been investigated for radio over fiber systems including the effects of variation in the laser linewidth and RF oscillator linewidth in this paper. Optical Single sideband signal is studied as it has tolerance for power degradation due to dispersion effects over a length of fiber. Investigations have been made out for Radio frequency of 30 GHz, with a continuous wave (CW) laser source of 1550 nm. CNR has been evaluated using Power Spectral Density(PSD) function.CNR is studied varying laser linewidth and RF oscillator linewidth for 2 Km fiber with chromatic dispersion D=17 ps/Km nm.

Multi-Band Radio-over-Fiber System Using Single Phase Modulator to Support Fixed and Mobile End Users
We propose a bidirectional Radio-over-Fiber (RoF) system with multi-band signals generation technique using a single phase modulator (PM). At central office (CO), a PM is used to modulate optical carrier and generated signal is transmitted through a single mode fiber (SMF). At base station (BS), three different signals are generated from the received optical signal, including 60 GHz millimeter ...

متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
