Simulative Investigation of 2.5 Gbps RZ Modulation Format Using Various Optical Sources in SOA Based RoF System

Abstract

Abstract

In this paper, the impact of various optical sources on the performance of semiconductor optical amplifier based radio over fiber (RoF) system has been analyzed. This RoF system has been modeled and analyzed using OptiSystem (14.0) software. The transmission performance of RoF system in terms of Q-factor, BER and eye height at different fiber lengths using various optical sources such as VCSEL, controlled pump laser, directly modulated laser and empirical laser has been measured and compared. An improvement in SNR has been observed by employing VCSEL with Mach-Zehnder modulator as compared to traditional optical sources in RoF system.

Keywords: VCSEL, controlled pump laser, directly modulated laser, empirical laser
