Luciol Instruments Correlation Optical Time-Domain Reflectometer (C-OTDR) for USNO

The United States Naval Observatory (USNO) is seeking to procure a Luciol Instruments Correlation Optical Time-Domain Reflectometer (C-OTDR) for the purpose of measuring one-way signal propagation delay over short-range passive fiber optic links in a GPS-reduced environment. The required instrument must have metrology-grade spatial resolution, a fully portable form factor, and be able to characterize signal delay through passive optical networks with high precision. The minimum essential characteristics of the instrument include a photon-counting correlation OTDR technology, three internal Fabry-Pérot laser sources, a spatial resolution capable of resolving events separated by 10 cm, and an event dead zone not exceeding 15 cm. • The instrument must be fully portable with an integrated display, operating system, and an internal rechargeable battery. • The instrument's software must allow the operator to manually input and adjust the Group Refractive Index with high precision. • The unit's test port must be fitted with an FC-APC connector. • The instrument must have a form factor that allows for cordless operation in field environments.
