Pat Sims on Community broadband networks
- 1. 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?
- 2. 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.

- In the beginning, the long haul fiber backbone infrastructure was use to travel from CO to CO, city to city, and country to country. We began to see that the sever limitations required us to use some of this backbone to place voice services over fiber to extend the reach of the copper infrastructure.

- In the early days of DSL, the same limitations caused us to use the fiber to extend the data services. Our first trials with DSL did not include voice, that came later…..
- With the advent of ever expanding mobile services, again, we used the backbone to extend our wireless capabilities….
- Business services requiring 10Mbps force us to move into the Metro Ethernet world and we were seeing the beginning IP over SONET and SDH. This was the first time we started building the fiber infrastructure for an access network.
- In the early development of BPON and EPON, we found a need to even extend the reach of PON services beyond 20km to areas 60-100km from the Central offices. We were already building the fiber-to-the-home networks with a 20km reach, and the transition was an easy one.
- We are finally moving into an all IP network where we are building new fiber infrastructures to include Ethernet Protected Rings. Again, we are placing more fiber into the Network.
