NIST intends to award a sole-source, firm-fixed-price contract for the installation and termination of 48 strands of dark fiber, plus activation and testing of 2 strands, between NIST facilities in Boulder and Fort Collins, Colorado. The scope also includes a 12-month renewable lease for use of the fiber infrastructure and access to an In-Line Amplifier (ILA) site for the same period. Performance will take place in the Fort Collins and Boulder, Colorado area. This is not a competitive solicitation, but interested parties may submit a capabilities statement to challenge the sole-source action. No budget amount or performance timeline is specified in the notice.
