| dc.description.abstract | Research and development of telecommunications technology continues to
progress to meet human needs in communicating. Fiber optic communication system is one
of the best technologies used for today's telecommunication needs. The Dense Wavelength
Division Multiplexing (DWDM) system is a development of optical fiber communication
system technology which has very significant advantages compared to previous
technologies. However, the Dense Wavelength Division Multiplexing ((DWDM) system
has a weakness that can affect system performance, namely the non-linearity effect. One of
the non-linearity effects that occurs in Dense Wavelength Division Multiplexing (DWDM)
systems is Four Wave Mixing (FWM). The effect of Four Wave Mixing is very influential
with changes in optical power in Dense Wavelength Division Multiplexing (DWDM)
systems so that optical amplifiers are needed such as Erbium Doped Fiber Amplifier
(EDFA), Semiconductor Optical Amplifier (SOA) and Raman Amplifier.This thesis will
discuss a comparative analysis of the use of optical amplifiers against the effect of Four
Wave Mixing on Dense Wavelength Division Multiplexing (DWDM) systems.The test was
carried out using software Optisystem 7.0 by analyzing the Q factor and BER values of
each optical amplifier.This study used two schemes, namely scheme 1 is to change the input
variable cable length 50 – 200 km and bitrate 10 Gbps, 40 Gbps, 100 Gbps. Scheme 2 used
in this test is to change the transmitter power value from 0 – 4 dBm to improve the best
simulation results for the first scheme. The results of this simulation indicate that the
Erbium Doped Fiber Amplifier (EDFA) optical amplifier has the best performance of the
other optical amplifiers when the effect of Four Wave Mixing occurs where the maximum
Q Factor value is 6,43824 with a BER of 5,04x10-11 in the simulation test scheme 1 and the
maximum Q Factor value is 6,71442 with a BER of 7,89x10-12 in simulation test scheme 2. | en_US |
