ANALISIS DISPERSION POWER PENALTY PADA AREA RING-1 JARINGAN LOKAL AKSES FIBER STO GATOT SUBROTO
Abstract: Fiber attenuation
caused by chromatic
dispersion and modal
dispersion is commonly referred to as a dispersion power
penalty. In the wave transmitted by transmitter, dispersion occurred, caused
degradation of signal quality, so that the signal receiver is not as good as which is
being transmitted. In
this paper will
be discussed about
the impact of
dispersion power penalty in ring-1 STO Gatot Subroto area. Analysis was
done to several factors that can
cause dispersion power
penalty, which are
distance, wavelength, and
data rate being used. The calculation with available
data and specification has been done, so that the routes with the
biggest and the
smallest dispersion power
penalty can be detected.
The biggest dispersion power
penalty happened in Palma Citra – Umawar route at distance of 9.387 km with =1550 nm
and data rate
622.08 Mbps. While
the smallest was
1.221710dB, happened in Tifa – STO Gatot Subroto route at distance of
1.626 km with=1310 nm and data rate 155.52 Mbps. All those calculations were
still in permissible limit, not more than 2 dB. Furthermore from some routes
were obtained very small dispersion power penalty. The bigger the fiber length
and data rate, the bigger the dispersion
power penalty is. Finally it can be concluded
that fiber length,
wavelength, and data
rate are equivalent
to the dispersion power penalty.
