Erbium doped fiber amplifier (EDFA) has greatly helped in overcoming the propagation loses which are of biggest concern for next generation wavelength division multiplexing (WDM)/time division multiplexing (TDM) passive optical network (PON). This study is To characterize the performance of high-concentration EDFAs and the effect of the concentration quenching (homogeneous up-conversion and clu...

In this paper, the performance and feasibility of a hybrid wavelength division multiplexing/time division multiplexing passive optical network (WDM/TDM PON) system with 128 optical network units (ONUs) is analysed. In this system, triple play services (video, voice and data) are successfully communicated through a distance of up to 28 km. Moreover, we analysed and compared the performance of va...

In this paper we investigate the performance of an Optical Code Division Multiplexing/Wavelength Division Multiplexing (WDM/OCDM) Optical Packet Switch when impairment due to both Multiple Access Interference and Beat noise are taken into account. Analytical models are introduced to dimension the switch resources, in particular the number of optical codes carried on each wavelength. The Packet ...

Optical network based on wavelength-division-multiplexing (WDM) technology will be a most active research topic in the 21st century. This paper describes a WDM multiple-wavelength transmitter and several key corresponding devices for optical network, including ASE spectrum-sliced multiplewavelength optical source, optical add/drop multiplexer (OADM), semiconductor optical amplifier (SOA), as we...

ÐIn this paper, we study distributed path reservation protocols for multiplexed all-optical interconnection networks. The path reservation protocols negotiate the reservation and establishment of connections that arrive dynamically to the network. These protocols can be applied to both wavelength division multiplexing (WDM) and time division multiplexing (TDM) networks. Two classes of protocols...

In this paper, we propose a time-token multi-Gb/s Wavelength Division Multiplexing Fibre Distributed Data Interface (WDM/FDDI) architecture and examine its throughput efficiency and delay under heavy load for different network configuration using discrete event simulator.

This paper describes a receiver for Wavelength Division Multiplexed (WDM) optical networks that employs Subcarrier Multiplexing (SCM) techniques to implement the control channels. The control channels operate in the 1 GHz to 2 GHz band.

All-optical networks that employ wavelength division multiplexing (WDM) are an attractive architecture for future high-speed networks. Through WDM, multiple channels are created on a single fiber, and an aggregate network bandwidth far greater than the peak electronic processing speed can be realized. This paper provides a review and an extensive bibliography of proposed media access control (M...

Wavelength Division Multiplexed (WDM) networking technology has been identified as a suitable candidate for future wide area network (WAN) environments, due to its potential ability to meet rising demands of high bandwidth and low latency communication. As traffic demand in the Internet increases exponentially, Wavelength Division Multiplexing (WDM) networks with Terabits per second bandwidth p...
