In this paper, the parameters of optical amplifiers are evaluated using numerical methods with Optisystem software. The main objective evaluation is implementation an telecommunication architecture, able to push back current limits, due a more and restricted bandwidth following demand which does not stop growing. We start from study classical architecture network external modulation provided by...

HUANG, SHU. Network design and optimizations with applications in optical and wireless networks. (Under the direction of Dr. Rudra Dutta). Typically, enterprise networks may incorporate Wide Area Networks (WANs), Metro Area Networks (MANs) and Local Area Networks (LANs). These networks have very different characteristics in terms of the physical media, data link layer and network layer protocol...

In this thesis, the potential of upgrading Passive Optical Networks in order to increase available bandwidth and expand in services and number of users is studied. The upgrade is feasible through the adoption of orthogonal modulation techniques –used in other types of networksadapted adequately to the specific needs of a passive optical network. At first, it is investigated and recorded the sta...

A promising option to raising busty interchange in system communication could be Optical Burst Switched (OBS) networks among scalable and support routing effective. The routing schemes with disputation resolution got much interest, because the OBS network is buffer less in character. Because the deflection steering can use limited optical buffering or actually no buffering thus the choice or de...
