Abstract

In this paper represents, parameters are factors that decide use of particular protocol for particular application. Different protocols for routing are used to increase utilization of bandwidth. Here we have discussed about best protocol for routing. OPNET is used to examine various parameters of Protocols RIP, EIGRP, IGRP and OSPF. Results demonstrate five parameters on ends of transmitter and receiver. Analysis of transmitter and receiver parameters are described with detail for choosing best routing algorithm.

Keywords

Open Shortest Path First (OSPF), Router Information Protocols (RIP) and User Datagram Protocol (UDP).

Abstract

Long haul multichannel optical communication system is extremely affected by nonlinear effect like four wave mixing (FWM). The FWM effect depends on channel separation, number of channels and bit rates. This paper presents the design and performance analysis of FWM effect on bit error rate, Q-factor, eye opening, jitter etc. at variable bit rates and dispersion values.

Keywords

FWM (Four Wave Mixing), Dispersion, Bit Rates.

Abstract

Wireless network based on Radio over Fiber (RoF) technology has been proposed as a promising cost effective solution to meet ever increasing user bandwidth and wireless demands in broadband, interactive, and multimedia wireless services. In recent years, considerable attention has been devoted to the merging of radio frequency and optical fiber technologies aiming to increase the capacity and mobility of the access network. Since, it was first demonstrated for cordless or mobile telephone service in 1990, a lot of research has been carried out to investigate its limitations and develop new and high performance RoF technologies. This paper gives the comprehensive review of radio over fiber technology used in communication system. Architecture, applications, advantages and limitations of RoF technology are also discussed in this paper.

Keywords

Abstract

In radio-over-fiber (ROF) systems, optical carrier is modulated by the electrical signal and thus, converts the electrical signal to optical domain. This leads to the generation of up-converted signal bands. Although modulation is a necessary process for the faithful transmission of a signal, but it also degrades the modulated signal by generating distorted sidebands which causes reduction in the dynamic range of the system. Dispersion originated from the transmission fiber and other optical devices also change the phase relationship between the optical carrier and the modulated sidebands. This causes degradation of the modulated signal due to power fading. Mach-Zehnder modulator (MZM) is the most preferred modulator used in RoF systems. The performance of RoF system depends upon various parameters of Mach-Zehnder modulator (MZM) like RF bias, bias voltage, extinction ratio and insertion loss. In this paper the behavior of Lithium Niobate (LiNbO3) MZM is studied on various bias and extinction ratio ranges and a particular bias and extinction ratio is fixed at which the proposed ROF system gives the optimum results.

Keywords

RoF, RoFSO, MZM.
