EE290Q - Optical Networks: From Components to Services - Fall 2001

Prof. C. J. Chang-Hasnain  

Dr. John Strand

 

Overview

Rapid advances in optical devices have combined with explosive growth of  IP-based services to make optical networking a critical and exciting research area.  The challenge is to do the trade-offs needed to design the components needed by systems designers, who in turn must design the systems needed by optical transport  network architects, who must provide the service functionality needed by data networks. Needs and requirements percolate down this hierarchy and proposed solutions flow up.  This course will study each link in this chain, using specific applications such as ultra-long haul all-optical transport as a focus.  Alternative approaches to getting reconfigurability, reliability, low total cost, scalability, and other desirable functionality will be explored.  Background reading and lectures on optical systems, networks, and services will be provided as needed. 

The course will be divided into modules, each approximately one - two weeks in length:

  1. Optical Technology - Laser, Detectors, Modulation Format

  2. Introduction To Transport Networks - Types of networks; introduction to telecom networks and services; telecom infrastructure;  1st Generation Optical Networks (SONET/SDH); basics of transport network design & optimization; reliability and survivability.

  3. Wavelength Division Multiplexing: Technology - EDFA, Mux/Demux, Fiber Nonlinearities

  4. Wavelength Division Multiplexing: Network Considerations - Problems with all-optical networks; static optical network design; differences between metro and intercity optical networks; trading off system design and network design.

  5. Wavelength Switching (Optical Cross-Connects and OADM's): Technology - MEMS, LiNbO3 switches, Filters

  6. Wavelength Switching (Optical Cross-Connects and OADM's): Network Considerations - Alternative uses of optical switching technology; OADM architectural and economic consideration; optical/ electrical switch fabric network trade-offs.

  7. Software-Controlled Optics: Technology & Physical Layer Considerations -

  8. Software-Controlled Optics: The Optical Control Plane - Software control of large transport networks; Introduction to IP and related protocols; MPLambdaS/GMPLS; rapidly reconfigurable optical networks.

  9. Transparency and Ultra-Long-Haul Systems: Technology -

  10. Transparency and Ultra-Long-Haul Systems: Network Considerations - All-optical networks; routing with limited wavelength translation; controlling an all-optical network; multi-domain networks.
