Optical fiber is one of the most important communications media in communication
system. Due to its versatile advantages and negligible transmission loss it is used in high
speed data transmission. There are various types of optical fiber, the Fibe
r Bragg Grating
(FBG) is commonly chosen as important components to compensate the dispersion in
optical communication system. Because the low cost of filter for wavelength selection and
low insertion loss, it has also customized reflection spectrum and wide bandwidth. The
simulation of transmission system will be analyzed based on different parameters using
OptiSystem simulator. By simulating a model of communication system and using the
most suitable settings of the system which include input power, fiber cable length (km) and
attenuation coefficient (dB/km) at cable section, there are three different parameters will be
investigated, which are Signal power, Noise power, output power at receiver.
