Transmission Characteristics of Radio over Fiber (ROF) Millimeter Wave Systems in Local Area Optical Communication Networks

Abstract

In the present paper, we have proposed Radio over fiber (ROF) technology which allows radio frequency (RF) transmission directly over the optical fiber has attracted much attention due to its promising performance and operational cost reduction. The well known advantages of optical fiber as a transmission medium such as low loss, light weight, large bandwidth characteristics, small size and low cable cost make it the ideal and most flexible solution for efficiently transporting radio signals. We have presented and modeled with parametrical investigation the transmission performance characteristics of the ROF system that is modulated with multiple bit rates using different transmission techniques such as Soliton, and maximum time division multiplexing (MTDM) technique. These transmission techniques are employed through two ultra multiplexing techniques, 4 links space division multiplexing (SDM) plus multi channels dense wavelength division multiplexing (DWDM) over optical window of special interest. Moreover, we have analyzed and investigated Soliton, and MTDM transmission techniques to be processed to handle both transmission bit rate and product either per link or per channel for cables of multi-links (4-24 links/core).
