POWER INVESTIGATION IN RADIO OVER FIBER TRANSMISSION SYSTEM
Journal Title: International Journal of Electrical, Electronics and Mechanical Fundamentals (www.ijeemf.com) - Year 2012, Vol 3, Issue 1
Abstract
In this paper, we have analyzed the impact of laser-spectral width and differential delay due to chromatic dispersion, incorporating dual-electrode Mach–Zehnder modulator (DEMZM), in radio-over-fiber (RoF) transmission system and results have been obtained. The results are calculated for 10 to 30 Km optical single side band (OSSB)–RoF transmission system by varying the laser line width. RoF system with OSSB has been used as it is tolerable for power degradation due to a chromatic fiber- dispersion, through a standard single-mode fiber (SSMF) carried by a continuous wave (CW) laser at 1550 nm of laser-spectral width varying from 100MHz to 650 MHz with CW power of 10mW that modulates a single RF channel of 30GHz. It has been found that deployment of lasers with lower spectral width will help the telecom industry to reduce the designing cost of RoF communication systems.
