Abstract

The ever growing broadband internet applications have increased the traffic capacity and demand for wide network coverage. Radio over fiber (ROF) is a combination of Wireless as front end and Optical Fiber Communication as Back-haul networks. ROF network provides mobility for users with high quality bandwidth and better geographical access. In this paper, we analyze Q-factor, BER and eye patterns for various Modulation schemes such as MSK, DPSK, OQPSK, CPFSK and Q-CPFSK (Quadrature) by means of Bit-rate and fiber length. Our Simulation results shows that Q-CPFSK gives better performance compared to other schemes at Optical Carrier Frequency of 193.1THz.
