Abstract
This research explained how to establish the optical receiver sensitivity and the link power budget design in terms of quality factor, receiver power and bit error rate (BER) for several values of attenuation at 100km fiber length. The design parameters which were taken into consideration were a constricted transmitter, Zender modulator, attenuator, lowpass Bessel filter, Non-Return-to-Zero modulation format, CW laser, avalanche photodiode (APD) and PIN diode detectors and the type of network coding, Bit Error Rate Analyzer (BER) etc. The objective was achieved using optisystem 7 professional simulation software layout to design the power system budget and optical receiver circuit, the avalanche photodiode and PIN diode were used as the detector. Optisystem simulations were used to determine the optimum power and the receiver sensitivity for several values of attenuation. This research investigated and analyzed the performance of optical receiver at a wavelength of 1550nm. Simulations were made and the Bit Error Rate analyzer values for the various parameters taken. Several values of Q-Factor and Bit Error Rate were tabulated, and the corresponding graphs plotted. There was an improvement in the quality factor, the quality of signal with a low noise value and the extended transmission or propagation time was reduced.
Highlights
Optical fiber is a dielectric wave guide or medium in which information is transmitted through glass or plastic fiber, in the form of light [1]
The shaping of signal is executed by an amplifier with an automatic gain control (AGC) embedded in it followed by an amplifier with an equalizer circuit
This study is to compare the performance of avalanche photodiode (APD) and PIN detector in enhancing the sensitivity of optical receiver
Summary
Optical fiber is a dielectric wave guide or medium in which information (voice, data or video) is transmitted through glass or plastic fiber, in the form of light [1] It consists of the transmitter, optical lines and a receiver. The system obtained a 3dB sensitivity merits over PDM-QPSK in an optically preamplified receiver This possibility was made with respect to an integrated active thin film head for high density recording (digital recording). The shaping of signal is executed by an amplifier with an automatic gain control (AGC) embedded in it followed by an amplifier with an equalizer circuit This receiver has a linear channel unit having an active equalizer regulated by the photocurrent of the input network [5] and [9]
