66--Distributed Acoustic Sensing Interrogator Unit

The Bureau of Reclamation is seeking information from potential sources for a Distributed Acoustic Sensing (DAS) Interrogator Unit. The unit will be used to support ongoing and future project work, including DAS data collection using fiber optic cable already installed at Granby Dike No. 3. The unit should have specific mechanical, data collection, and sensing capabilities, as well as power supply requirements. Interested parties are requested to provide business information, including company name, address, point of contact, and relevant experience. • The DAS Interrogator Unit should be a Class 1M Laser Product • The unit should be 19-inch rack-mountable (4U) and have an operating temperature range of 0°C to 40°C (32°F to 104°F) • The unit should have a relative humidity range of up to 90%, non-condensing, and have SC/APC fiber connection types • The unit should have native sensing data type measurements of velocity and have a raw data output file format in HDF5 • The unit should have a max sensing fiber length of 30km or more and have a channel spacing of 1m or less
