Abstract
In this paper, we have exhibited the potential of the glass- and polymer-based
multimode fibers to be used in a radio over fiber (RoF) system in order to
extend the indoor coverage of the Wimedia multiband orthogonal frequency division
multiplexing (MB-OFDM) ultrawideband (UWB) standard. After the design of a
test setup operating at 850 nm, we have performed the physical characterization
of the RoF system especially the mask test compliance, the error vector magnitude
(EVM), or the relative constellation error (RCE) variation as a function of
the system parameters [radio frequency (RF) power, optical attenuation, fiber
length, laser bias current]. The transmission performance of both 200 and
480-Mb/s Wimedia signals is demonstrated through a 100-m link length of glass-
and polymer-based multimode fibers: transmission penalties are quantified
by RCE with values under the standard requirements. Two different behaviors
depending on the core material of the fiber have been identified in this study.
