Optical Networking / DWDM Basics (Dense Wave Division Multiplexing)

Presented by

Elizabeth Paige

About this talk

Optical networking delivers the distance, bandwidth scalability, resiliency, and manageability that broadband networks require. Review of optical networking technology and basics and explain how optical networks solve reachability, survivability, bandwidth growth, and maintenance challenges for broadband services. Key topics of discussion: What problems do optical networks solve? What are the major piece parts and important vocabulary? What do I have to think about when deploying? Any cool stuff on the market I should be aware of? What Can an Optical Network Do for Me? A couple DWDM basics... What are the Key Pieces of an Optical System? DWDM Basics What is a Transponder? DWDM Basics What is OTN Switching? DWDM Basics OTN Containers Any type of client signal: Ethernet, SONET, Fiber Channel, etc. What are the functions of a Line System? DWDM Basics Combining Waves using Wavelength Division Multiplexing (WDM) DWDM "Grids" What Determines How Much Spectrum I Use for Each Wavelength? Transponder Options Performance-Optimized Transport - 3 better knobs Manipulating Wavelengths... Brute Force Networking A Little Better - Fixed OADM units ROADM Networking - Where Networks are Trending Different Types of ROADMS different types of addidrop hardware Attenuation (loss) Reduces Optical Power No Free Lunch in the Analog World Dispersion - When Pulses Spread out Down the Fiber - 10G waves and below Technology, Design, and Deployment Considerations
