Luciol Cotsworks Sole Source Justification Redacted.pdf

This is a Justification for Sole Source document for Purchase Request/Document number 1301370889 issued by the United States Naval Observatory (USNO), the requiring activity. The procurement is restricted to a single supply source: a Luciol Instruments Correlation Optical Time-Domain Reflectometer (C-OTDR), Part Number LOR-223-SMF-1310FP/1550FP/1650FP-AFC, to be procured from Cotsworks, LLC, the only authorized reseller of Luciol products in the United States.

The customized device is a metrology-grade photon counting C-OTDR designed for ultra-high-resolution, single-ended distance and propagation delay measurements on passive Single-Mode Fiber links spanning hundreds of meters. Minimum essential characteristics include photon-counting/correlation OTDR technology with three internal Fabry-Pérot laser sources at 1310 nm, 1550 nm, and 1650 nm wavelengths; spatial resolution capable of resolving events separated by 10 centimeters with an event dead zone not exceeding 15 centimeters and optical pulse width of 1 nanosecond or less; a fully portable, standalone unit with integrated display and internal rechargeable battery for cordless field operation; software allowing manual input and adjustment of Group Refractive Index with high precision; and an FC-APC connector test port. The justification asserts that only the Luciol 220 OTDR series meets these specialized requirements for USNO's mission of maintaining precise timing signals and managing astronomy and physics equipment. The Independent Government Estimate (IGE) is $37,600.00, with a required award date of June 30, 2026 and an expected 20-week delivery lead time. The sole source justification is based on patent, copyright, or proprietary data limitations that preclude full and open competition.
