| dc.description.abstract | Nowadays the development of technology continues to increase, with the
increasing capacity of internet users, high-capacity data rate becomes a necessity, therefore
the design of long-distance fiber optic communication with high bitrate is required.
However, high-capacity data rates have disadvantages, dispersion is a problem for this
system. Therefore, using dispersion compensating fiber (DCF) is expected to optimize the
optical fiber design at these frequencies, especially from dispersion problems that can be
optimized for receiving-end. DCF is one good method used to handle dispersion problems,
because it has advantages such as wide bandwidth, good BER. The use of DCF in this final
project is applied to Single Mode Fiber (SM). The scheme used in this study is divided into
2 parts, the first is a simulation with DCF where there are 2 different schemes of SMF with
pre DCF, SM with post DCF, and lastly SM with DCF mounted in parallel, the three
schemes each are supported with Semiconductor Optical Amplifier (SOA) amplifier and
Raman Optical Amplifier (ROA) amplifier. With Q factor parameters and BER as
parameter feasibility. At the end of the study with 10 Gbps bitrate, . The pre compensation
scheme produces a Q factor of 6,2 and BER value of 2,26x10−10 at a distance of 100 km.
The post compensation scheme produces a Q factor with a value of 6.89 and BER is worth
2,68x10−12 at a distance of 300 km . The parallel compensation scheme produces a Q
factor of 7,2 and BER Worth 2,78x10−13 at a distance of 200 km. In the Raman optical
amplifier, the pre-compensation, post-compensation and parallel compensation schemes do
not meet the standard good optical link quality with a maximum Q factor of 2.8 and a BER
of 2,51x10−3 at a distance of 100 km with the post-compensation scheme. | en_US |
