Design of An All-Optical WDM Lightpath Concentrator
نویسندگان
چکیده
A design of a nonblocking, all-optical lightpath concentrator using WOC and WDM crossbar switches is presented. The proposed concentrator is highly scalable, cost-efficient, and can switch signals in both space and wavelength domains without requiring a separate wavelength conversion stage.

A Survey on Static Impairment-Aware Routing and Wavelength Assignment Heuristics in Optical WDM Networks
Physical layer impairments in optical fibers degrade the quality of the optical signal as it propagates along a lightpath. This leads to an increase in the Bit Error Rate (BER) of the optical signal and the corresponding lightpath becomes infeasible for communication if the BER crosses a certain threshold limit. Traditional RWA approaches assume an ideal physical layer medium and ignore the eff...
متن کاملFault management in IP-over-WDM networks: WDM protection versus IP restoration
We consider an IP-over-WDM network in which network nodes employ optical crossconnects and IP routers. Nodes are connected by fibers to form a mesh topology. Any two IP routers in this network can be connected together by an all-optical wavelength-division multiplexing (WDM) channel, called a lightpath, and the collection of lightpaths that are set up form a virtual topology. In this paper, we ...
متن کاملA Comparative Study of Node Architectures with Add/Drop Constraints in WDM Networks
The advent of WDM technology has resulted in transmission capacities that have increased manifold in recent years. The most common architecture used for establishing communication in WDM optical networks is wavelength routing, where data are transmitted over all-optical WDM channels, called lightpaths, which may span multiple consecutive fibers. A lightpath is realized by determining a path bet...

متن کاملInvestigation of rerouting system in Optical Network
Optical Wavelength Division Multiplexing (WDM) networks are high capacity telecommunications networks based on optical technologies and components that provide routing and restoration at wavelength level. High Capacity Optical WDM Networks are either reconfigured or reroute to meet the dynamic traffic demand of the various applications. However the demand varies with time and infrastructural de...
