Abstract
A radio over fiber (RoF) transmission system based
on a gain-switched laser as an optical comb source is proposed
and demonstrated. 12.5 Gb/s 16 quadrature amplitude modulation
(16 QAM) signal generation and transmission over 25 km
standard single-mode fiber is experimentally demonstrated using
a 60 GHz carrier. The phase noise of the 60 GHz signal resulting
from the beating of two partially phase uncorrelated optical tones is
theoretically studied and experimentally investigated. Phase noise
comparison with different linewidth comb sources is implemented
in the proposed RoF system, and the performance of the various
systems with different levels of phase noise is presented.
