There was an improvement in the gain, quality factor, the quality of signal with a low noise value and the extended transmission or propagation time was reduced. Several values of Q-Factor and Bit Error Rate were tabulated and the corresponding graphs plotted. Simulations were made and the Bit Error Rate analyzer values taken. This research investigated and analyzed the performance of the optical receiver at a wavelength of 1550nm, optic fiber of length 100km. Optisystem simulation was used to determine the optimum gain and the receiver sensitivity for several values of attenuation. The procedure of the design was to first improve on the gain using Erbium Doped Fiber Amplifier (EDFA), reduce loss and propagation time and increase the signal flow.

Main includes parameters for accessing a laser (Frequency, Power, Line width, Initial phase) Polarization Simulation Noise Random numbers Display parameters in the. The CW Laser has ve parameter categories. Component parameters are organized by categories. This increase in the volume of transmitted signals causes severe traffic congestion, making the receiver insensitive, prolong the signal processing time and identified bits wrongly. The CW Laser Properties dialog box appears (see Figure 20). The band width of WDM MUX used at the transmitter side is 80 GHz. The frequency range of CW Laser used is 193.1THz to 193.4THz. The unlimited bandwidth of an optical fiber create a path for large volume of signals to flow rapidly in a fraction of a seconds. The work of Mach Zehnder modulator is to modulate the signal from the CW Laser. of Single & Hybrid Optical Amplifiers for DWDM System using Optisystem. With the increasing demand and growth in optical telecommunication networks, the sensitivity of an optical receiver become an important part of telecommunication transmission networks. source, NRZ electrical driver, CW laser source and external Mach-Zehnder.
