ABSTRACT: The combination of Radio Frequency and
Optical Fiber has resulted high capacity transmission at lower costs components
and makes Radio over Fiber as a current trend of large broadband communication.
In Fiber optics field, the use of Fiber Bragg Grating (FBG) was been proposed
in recent research with different purpose of uses. However, the compensation of
dispersion method of Fiber Bragg Grating (FBG) can boost significantly the
system performance. This paper investigates the performance capacity
improvement of adaptive Radio over Fiber system. The system design was
performed using OptiSystem 7.0 software, which 10 Gb/s Non Return to Zero (NRZ)
signal was launched into 50 Km Universal Mode Fiber and Fiber Bragg Grating was
used as a compensator of dispersion before frequency up conversion. Therefore,
the system performances were investigated by comparing the Bit Error Rate (BER)
and Q-factors of Positive Intrinsic Negative (PIN) and Ultrafast Avalanche
Photodiode (APD) as optical receivers. The Eye diagram analyzer showed acceptable
improvement due to use of Fiber Bragg Grating as a compensator of dispersion.
