This study has discussed some shortages of IP over SDH used currently, and has proposed the necessities of IP over DWDM. It has given the structure of IP over DWDM, and has explained why it can increase its bandwidth when transiting IP packets over DWDM. The study has also discussed the two methods of realizing IP over DWDM transmission network.

Abstract This paper presents on the design and analysis of Dense Wavelength Division Multiplexing Passive Optical Network (DWDM-PON) which is upcoming trend technology nowadays to transmit up 40 Gbps data. Various modulation techniques such as Non-Return Zero (NRZ), Return-Zero (RZ) duo binary coding are simulated in this DWDM-PON. Using OptiSystem software, DWDM-PON designed for 32 channels wi...

This paper deals with the concept of transmitting raw IP packets over an optical layer, which employs DWDM for increasing its bandwidth demand. It also gives a brief introduction to DWDM systems. The requirements for creating an all optical networks and the issues pertaining such an evolution have been discussed here. The protocol architecture based on multiprotocol lambda switching has also be...

In DWDM system, the major non-linearities such as SRS and FWM occurs simultaneously in Long-Haul Communication. As the optical signal propagate through the fiber undergoes power fluctuations and crosstalk between the channels in DWDM system. Due to this major problem, the performance of DWDM system get degrades. In this paper, the effect of SRS and FWM affecting the original Dense Wavelength Di...

is paper describes the design and implementation of the optical DWDM backbone of CESNET2 network Phase 6 in 2007. e article is divided into the following logical parts: technology and DWDM network deployment, three-way ROADM implementation and L2 over DWDM implementation.

The design of Interleaver/Deinterleavers using Fibonacciclass quasistructures is proposed. We introduce an optical passive configuration composed of Fibonacci quasistructures and circulators which acts as interleaver and deinterleaver. Odd and even channels are interleaved/deinterleaved with dense wavelength-division multiplexing (DWDM) multichannel filter based on Fibonacci quasi-periodic stru...

:This article covers functions and applications of DWDM system components. The operation of each component is discussed indivi dually. DWDM terminology like Attenuation, dispersion, and optical signal to noise ratio (OSNR) are measures of optical signal quality and are the key factors involved in DWDM system design and operation. From transmitter to receiver, the quality of the optical signal a...

This article addresses the issues of scalable end-to-end QoS in Metropolitan DWDM networks serving as transit networks for IP access networks. DWDM o ering few wavelengths have in the past been deployed in backbone networks to upgrade point-to-point transmission where sharing is based on coarse granularity. This type of DWDM backbone networks o ering few lightpaths, provides no support for QoS ...

Frees Space Optical (FSO) system employs empty space to transfer information between the transmitter and receiver using light. The single-beam Single Input Output (SISO) technology is well known for being subject air attenuation induced by weather conditions, which decreases performance link range data quality. proposed in this research a combination of DWDM MIMO approaches address issue. based...

As for the problems of complexity and long cycle in the DWDM design, part of problems needed to be considered in DWDM system design were analyzed. An optimized point-to-point DWDM transmission system was designed. Optical fiber communication system with 40Gbit / s and 32 channel was designed and simulated by Optisystem. Based on the study above, the model witch can inhibit dispersion and fiber ...
