Descrição: By the discovery of the optical fiber, it has become the most widely used technique for communication purposes. The major limiting factor which degrades the efficiency of optical communication is the dispersion, as it causes the traveling pulse along the fiber to spread and change its shape causing inter symbol interference. The main objective of this paper is to reduce the dispersion effects. This is carried out by using four cascaded tanh apodized FBGs, which is the main contribution in our work, to enhance the spectral linewidth of light source as it works like a band pass filter that reflects a certain signal wavelength and passes the others. A maximum bit rate per channel of 709.9905 Gbit/s is achieved in silica-doped optical fibers based on the maximum time division multiplexing (MTDM) transmission technique at a temperature of 20 °C, a relative refractive index difference of 0.002, a doping ratio of 0.2, a signal wavelength of 1.65 µm and a 10 km link length. Three conditions are considered and compared in our work: MTDM technique only, MTDM with raised cosine apodized FBG, and MTDM with tanh apodized FBG.
