NetworkNH DWDM and 

Carrier Ethernet

Interconnection Map

NetworkNH comprises a system of fiber-based networks, leased data carrier circuits, and internet carrier services. NetworkNH includes engineering and support staff, with monitoring and operations tools, redundant power systems, and operations centers across New Hampshire.  

The NetworkNH IBEAM, New Hampshire’s Regional Optical Network, is built with over a thousand miles of privately leased fiber-optic cable*, and the optical network equipment to pass data across the fiber. The IBEAM includes two inter-connected systems:

  • 400-Gigabit DWDM ring connecting New Hampshire’s four largest research/residential institutions to each other and to the Internet and Internet2 at the Northern Crossroads PoP in Cambridge MA, and Internet2 facility in Albany NY, and partner institutions across the region.
  • 40-Gigabit Carrier Ethernet ring around New Hampshire providing Gigabit layer-2 and layer-3 services to roughly thirty partner institutions.

IBEAM DWDM-connected partners include those institutions within USNH: Keene State College, Plymouth State University, the University of New Hampshire; as well as Dartmouth college. The IBEAM DWDM system interconnects with the Regional networks of the University System of Maine, the University of Vermont, 

The New Hampshire I-Beam

 UMassNet, and the NEREN network across Massachusetts, Rhode Island, and Connecticut.

IBEAM Carrier Ethernet partners include Granite State College, the Community College System of New Hampshire, UNH Cooperative Extension, several County offices, the North Country Education Services, UNH at Manchester, the UNH School of Law School, New Hampshire SafeNet, the Northern Community Investment Corporation, and the University System of New Hampshire.  

NetworkNH also leases data circuits from a variety of carriers to provide secondary 

connection for IBEAM partners and to connect those partners not yet within reach of the IBEAM fiber footprint.

Many of our partners also subscribe to ConnectNH collaboration services.

* The IBEAM fiber lease acquisition has been funded by the University System of New Hampshire, the University of Maine System, and grants from the National Telecommunications & Information Administration, the National Science Foundation, and the National Institutes of Health.
