WHAT'S IN A NODE?

摘要

In building fiber-to-the-node networks, telecom service providers are relying extensively on their experience with outside plant engineering while future-proofing their networks for what they know will be bandwidth-intensive applications. For example, AT&T is putting most of the nodes for its Project Lightspeed network at the existing service area interface (SAI) because that makes the most sense in a carrier service area-designed network, said Matthew Wallace, executive director of advanced access technologies for AT&T. The CSA design standards are based on Bellcore and Bell Labs engineering standards that go back decades.
