Abstract

his paper presents forty channels dense wavelength-division
multiplexing (DWDM) system using a hybrid optical amplifier
composed of Raman optical amplifiers and erbium doped fiber
amplifier (EDFA). The forty channel DWDM system have been
designed and simulated to study the behavior of the proposed
Raman-EDFA amplifier as preamplifier and in-line amplifier to
select one which have better performance with maximum
transmission distance. These configurations are transmitted and
measured over different distances. The optical link composed of
dispersion compensated fiber (DCF) and single mode fiber (SMF)
to limit the chromatic dispersion. The performance of the proposed
hybrid optical amplifier as preamplifier and as in-line amplifier were
evaluated by bit error rate (BER), output power, gain and quality
factor (QF). Moreover, it calculate the number of spans and the
length of each span which give maximum transmission distance for
Raman-EDFA hybrid amplifier using the two positions as in-line
amplifier along the fiber and as preamplifier at the end of the fiber.
It is found that Raman-EDFA hybrid amplifier as preamplifier
performed better than in-line optical amplifier.
