Analisis Pengaruh Fiber Kompensator Dispersi yang Dikombinasikan dengan Penguat Optik Semikonduktor dan Raman

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.
