An Accurate Model for Economical Budget Study and Performance Analysis of Silica and Plastic Optical fibers for Short Range Optical Communication Network Applications With Different Multiplexing Techniques

This paper has presented the new progress of optical communication system taking into account the following items such as its ultimate channel bandwidth, its available transmission bit rates based on non return to zero (NRZ) coding and Shannon transmission techniques, its ultimate transmission link bandwidth and its transmission length. Three items of special emphasis in the basic design of optical communication system network planning are: either silica or plastic optical fibers as link, and the aluminum gallium arsenide (AlGaAs) optical source cast as vertical cavity surface emitting laser diode (VCSELD), at operating wavelength of 850 nm, 1300 nm and 1550 nm with the integration of silicon avalanche photo diode at the receiving side. special emphasis is focused on the above three items under different operating conditions including both the thermal and spectral effects. The optical communication system network is built up on the bases of AlGaAs VCSELD and two optical links where spectral and thermal effects of the plastic and silica fibers links are included with silicon avalanche photodiode. The high speed transmission performance is processed namely the channel bandwidth, transmission bit rate, optical signal to noise ratio, average repeater spacing, cable cost planning considerations in the optical link side through different effects (ambient temperature, refractive index change, and optical signal wavelength). As well as signal to noise ratio and bit error rates are the major interesting parameters in the receiving side with the used silica and plastic fibers links.
