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.
