Distributed Acoustic Sensing (DAS) interrogator

The U.S. Geological Survey seeks quotes for a distributed acoustic sensing interrogator to support its ShakeAlert earthquake early warning system. The interrogator must be capable of simultaneously monitoring multiple submarine fiber optic cables located offshore of major west coast cities. Quotes are due by February 12, 2024 and must include country of manufacture, technical specifications, and evidence of experience collecting high-quality seismic data and detecting earthquakes out to 100km. The successful offeror will deliver a rack-mountable interrogator by December 2024 that can collect data from at least four fibers at 200 samples per second without switching, integrate with USGS algorithms, and include at least 50TB of storage.

No set-aside is designated for this procurement. The primary NAICS code is 334516, Test and Measuring Equipment Manufacturing, and the size standard is 1,000 employees. The place of performance will be at USGS facilities monitoring submarine cables offshore of California, Oregon, and Washington. Offerors must demonstrate the proposed interrogator can collect seismic data from multiple fibers simultaneously to support the ShakeAlert system.
