Analytical Dispersion Compensation Technique To Transmit Optical Millimeter-Waves Over Long Fiber Links

摘要

Multi-gigabits per second millimeter-waves (MMW) have found wide application in a variety of areas. There is always a demand for not only discovering costly effective ways of generating MMW, but also carrying high bit rate signals, up to 2.5 Gb/s, as long as possible. In this paper, a development for dispersion compensation technique for the transmission system of optically generated MMW signals is presented. Optical MMW that modulated with 2.5 Gb/s, could not travel safely through a fiber span for more than 70 Km. Applying analytical design for dispersion compensation to the same MMW signal that generated with the same way, it is possible to transmit it with very low bit error rate (BER) through a fiber length more than 118.8 Km. The proposed technique for dispersion compensation is based on modifying the parameters of the fiber link and the transmitted signal as well. A comparison between the results with and without the abovementioned technique is also presented in this paper.
