A WDM optical communication link a senior project

Wavelength division multiplexing optical fiber networks rest mainly on two components, the network access station (NAS) and the optical network node (ONN). The design of the network depends heavily on the technology underlying these components, opto-electronics for NAS and photonics for ONN. These areas show large and fast development which will have an impact on network design. A series of characterization experiments were set up and conducted for characterization of the optical fiber and the laser diodes used. Among the important components in this project was a self study item of the student choice for one of the components of the link or the different aspects of the WDM systems and networks. The main features of the component with up to date information were required. The items ranged from fiber fabrication to soliton propagation in fibers and from WDM network layers to topologies as well as DFB and quantum well lasers
