Distributed Acoustic Sensing Interrogator Unit

The Bureau of Reclamation intends to solicit a Distributed Acoustic Sensing Interrogator Unit and has issued a sources-sought notice with responses due by 4:00 PM MDT on July 8, 2026. The procurement is not set-aside; however, the government is actively seeking responses from small businesses, including 8(a), Service-Disabled Veteran-Owned, HUBzone, and Women-Owned concerns, and has indicated the effort may qualify as a total Small Business Set-Aside under NAICS 541715 pending market research results.

The DAS Interrogator Unit must be a 4U, 19-inch rack-mountable Class 1M laser product capable of supporting sensing fiber lengths of 30 kilometers or more with native velocity measurements. Technical specifications include HDF5 raw data output format, channel spacing of 1 meter or less, configurable gauge length options from 1 meter to 100 meters minimum, sampling resolution of 0.8 meters or less, and sampling rates of 200,000 samples-per-second (100 kilohertz) or greater. The unit requires AC power input of 100–240 VAC, 40–60 hertz, with typical operation at 150 watts, and SC/APC fiber connections compatible with single-mode, enhanced backscatter, and multi-mode fiber types. Deployment occurs at various Bureau of Reclamation facilities. The acquisition includes extended warranty, annual firmware upgrades, and annual support packages.

Responses must address company information, relevant experience, manufacturing capabilities, teaming arrangements, and any anticipated challenges. Submit to Aubrie Watson, Contract Specialist, at aubrielle_watson@ios.doi.gov. NAICS 541715; PSC 6655.
