NLR Supercharges Infrastructure with Community's Assistance

The upgrade of NLR's northern loop to a next-generation optical transport platform has been completed in record time, thanks to strong support from across NLR's community.

Further boosting the performance of the NLR backbone, the upgrade sets the stage for total capacity increases beyond the current 400 gigabits per second (Gbps).

The massive effort involved installing 143 Cisco ONS 15454 DWDM platforms and 200 transponder cards in 116 physical locations across 6,750 miles of NLR's total 12,000 mile footprint. Covered Los Angeles through Seattle, Chicago and Washington, DC to Jacksonville, Florida.

Many thanks to BoreasNet, CENIC, Pacific Northwest Gigapop, MCNC and Internet2 who loaned or leased fiber and waves to NLR to ensure uninterrupted service for NLR users during the upgrade. Also our appreciation to LightRiver Technologies, for handling the physical installation, turn-up, performance testing and removal of the obsolete gear, to Level 3 Communications for running new fiber cross-connects and helping with the preparation for the installation and to Cisco which, in addition to providing the 15454's, performed service quality and platform monitoring and testing services.
