Transcript of Pat Sims on Community broadband networks
Technical Review
• Next Generation Architectures
– Fiber Concepts are Changing
» Are we prepared?
– IP Applications and Services
» Anything New?
– PON Defined
» Not Just P2MP anymore.
– Video
» Beyond IP and HDTV
– New Bandwidth Requirements
» Can the existing networks handle it?
Important Concepts
• Design process for access solutions over fiber begin in the CO/HE, moves thru the Optical Distribution Network and terminates at or near the subscriber’s premises. Design for the SA is key.
• The current generation of access electronics is estimated to have a life cycle of 3-5 years. Up to 100Mbps today, 1-Gbps tomorrow.
• Conservative estimates place the physical infrastructure of the fiber network with a 20-35 year life expectancy.
(Personal Observation – Should last 50+ years.)
• Proper fiber techniques will provide for the a smoothly run network today and a foundation for the transition between the current generation of access electronics and the next.
