Abstract In this paper, we demonstrate the importance of the number of wavelength division multiplexing (WDM) channels and the network traffic variability on the dynamics of a cascade of erbium-doped fibre amplifiers (EDFAs) fed by packet traffic in burst mode. The dynamics are determined using a numerical model incorporating time variation effects in the EDFA. Calculations are based on the sol...

The future Internet will require the transport of a wide range of services including high bandwidth one-to-many applications, with a dynamic interconnection of devices. WDM layer support realizes such services in a transparent, reliable and efficient way. Most of the recent studies have been focused on efficiently building and configuring light-paths for unicast or light-trees for multicast in ...

A wavelength division multiplexing (WDM) optical path-based Internet protocol (IP) backbone network is proposed as a cost-effective way of realizing robust IP-over-photonic systems. The WDM optical path is based on WDM transmission and wavelength routing. Between end-to-end IP backbone routers, the WDM optical path, a fat and robust optical pipe, is defined across photonic transport systems (PT...

Optical WDM networks are attracting more and more attentions because of its huge bandwidth to meet the ever increasing demand of modern networking applications. In this paper we study supporting multicast in WDM switching networks. Multicast is the operation to send information from one source to multiple destinations. In WDM switching networks, contention occurs when one output fiber is the de...

Purpose – The problem of Wavelength Division Multiplexing (WDM) network planning for a given set of lightpath demands in a mesh topology network is to select lightpath routes and then allocate wavelength channels to the lightpaths. In WDM network planning, a scenario study is to find out the network performance under different lightpath demands and/or different network resource configurations. ...

We experimentally demonstrate 4×75 Gbit/s optically amplified 4-level pulse amplitude modulation (PAM-4) transmission based on an external Mach-Zehnder modulator (MZM) and electro-absorption (EAM) for monolithically integrable intensity direct detection wavelength division multiplexed passive optical networks (WDM-PONs). The effects of semiconductor amplifier (SOA)-induced nonlinear distortions...

Demands for networks of higher and higher capacities are increasing dramatically with the growth of the Internet and the World Wide Web. All-optical wavelength-division multiplexing (WDM) networks is the most promising candidate to fulfill the bandwidth requirement of the Broadband Integrated Services Digital Network (B-ISDN). In WDM networks, the huge bandwidth available on an optical fiber is...

Introduction The use of the long-wavelength-band (Lband) is attractive for both increasing the capacity of wavelength division multiplexing (WDM) systems and has been used in WDM transmission experiments at over 1 Tb/s. Recently, a gain bandwidth of about 80nm has been achieved by integrating the L-band EDFA in parallel with conventional band (Cband) EDFA [1]. Moreover, the L-band EDFAs will ma...

Radio over Fiber (RoF) technology the integration of microwave and optical networks is a potential solution for increasing capacity and mobility as well as decreasing costs in the broadband access network. The concept of RoF means to transport information over optical fiber by modulating the light with radio frequency signal (RF) or at an intermediate frequency signal (IF) to take advantage of ...
