The document discusses the network infrastructure needs for modern communities and the advances that have been made to meet these needs. It focuses on optical networks for the core, transport, and access layers. Key needs addressed include high bandwidth, low latency, reliability, and low costs. Advances in optical networking technologies now provide packet switched, scalable, and reconfigurable core and transport networks operating at speeds up to 100 Gbps. Access networks have transitioned to passive and active optical technologies like GPON, WDM PON, and DWDM to deliver high-speed connectivity to homes and businesses.
