Opportunities for New Data Architectures in U.S. Incumbent Service Provider Networks

Our recently released report, Opportunities for New Data Architectures in U.S. Incumbent Service Provider Networks describes the fiber networks of the U.S. incumbent carriers. This analysis defines the total available market for new technologies that are being proposed for the U.S. incumbent fiber networks, including:

  • Next Generation SONET
  • Switched Gigabit Ethernet
  • Resilient Packet Ring (RPR)
  • Passive Optical Network (PONs)

Next Generation adds packet-based Ethernet and IP services to SONET systems. Gigabit Ethernet can be implemented in the core network, in the access network, and can deliver services to subscribers. RPR fits into the access network and also can deliver services to subscribers. PONs is used only to provide services to subscribers.This analysis was accomplished by using a detailed database from Qwest that describes the details of their fiber network and the fiber systems installed in their fiber access network that have customer-facing interfaces. The FCC ARMIS database was used to make estimates for all of the major U.S. incumbent networks.This analysis concludes that there are that up to 75% of the 59,000 locations in the U.S. incumbent carriers are candidates for these new technologies. The limitations come from the topology of the network and the availability of spare fiber in order to support new network applications.
