Network Hierarchy Core/Wide Area Networks - 100's to 100's of kilometers - Countries, Continents Data Rate, Cost Metropolitan/Aggregation Networks - 10's of kilometers - Cities Access/Local Area Networks - kilometers - Campuses, Neighborhoods, Buildings, Homes OPTI 500, Spring 2011, Lecture 2, Introduction to Networks 13
Networks = Fiber Amplifier Signal Dispersion Compensation Transmission links are lengths of optical fiber (or free-space beam paths) that may have components inserted that condition the optical signal 14
Fibers 15
Network Nodes Transceiver = Electrical Input Diode Laser/ LED Driver Photodiode Output Input = Tranceiver + Tranceiver + Electrical Output Post Amp TIA Most nodes contain one or more optical transceivers 16
O-O Network Nodes OO = Splitter OO = λ 1 λ j λ n Add-Drop Multiplexer λ 1 λ i λ n λ i λ j Transparent optical-to-optical nodes are becoming more common. 17

Network Convergence Network convergence refers to the use of both datacom and telecom protocols and hardware in the same network. The motivation is to share resources and to combine the flexibility of datacom networks with the high capacity and Quality of Service assurance of telecom networks 24
A More Fully Converged Network IP MPLS ATM SONET WDM The communication infrastructure has evolved so that complicated convergence schemes like this are widely used today People agree that simplification would be a good thing 25
IP over WDM IP? WDM IP is here to stay So is WDM The question is how to most efficiently build networks that use both Real world solutions must take into account the current network infrastructure OPTI 500, Spring 2011, Lecture 8, Network Convergence 26
