  1. ADVANCED TECHNOLOGY IN OPTICAL FIBER COMMUNICATION SYSTEM-DWDM Under the guidance of Mr. R. K. Dash by Deepak Kumar Sadangi Roll no – EE200118034

  2. The Challenge: • The communication’s • revolutions- • LASER &Fiber Optics • Principle implemented- • Total internal reflection • Advantage over its • Predecessor- • greater bandwidth

  3. The Change: • 1980 - OFCS • 1990 – EDFA • Confluence of 20th & 21st century – • Intelligent All-Optical Network

  4. A New Wrinkle: • The new technology – DWDM • - advantages of DWDM over TDM • TDM • DWDM

  5. DWDM System – • - optical transmission principles • channel spacing & signal trace • signal direction – unidirectional, bidirectional

  6. Optical amplifiers • EDFA • DBFA • EBFA • Flat gain • Slow saturation • Low noise • Synchronization • Security

  7. DWDM Components: • Components of DWDM system – Add/Drop multiplexer, Optical cross connect, Optical splitter • WADM

  8. OXC • DWDM architecture

  9. Wavelength conversion in optical networks: • Categories of Wavelength conversion • No conversion • Full conversion • Limited- • conversion • Fixed conversion • Sparse wavelength conversion

  10. Concluding notes: • Possibility of coexistence of • two optical layers • Survival of SONET • The next big challenge – • managing 100+ wavelength What holds us back in this evolution of DWDM?

  11. Thank You
