About this file
This document is a Performance Work Statement (PWS) for Control Net Fiber Optic Inspection and Cleaning for the USNS SUPPLY (TAOE 6) naval vessel. The PWS details a comprehensive fiber optic maintenance task involving approximately 425 individual connectors across the ship's Data Acquisition Unit (DAU) control net system. The contractor is required to provide specialized equipment including an EXFO Handheld Display, AFL Visual Fault Locator, Optical Wavelength Laboratories Fiber Optic Tester, and various cleaning materials.
The work involves systematically disconnecting, testing, cleaning, and polishing fiber optic connections, with strict requirements including using only 99% Isopropyl Alcohol for cleaning, testing cable signals at specific wavelengths (1300 nm for single mode, 850/1300 nm for multimode), and ensuring less than 5 dB signal loss. The contractor must estimate and perform up to 30 splices, cover splices with heat shrink, and potentially replace cables that cannot be repaired. Additional tasks include vacuum cleaning DAU cabinets, verifying system communication with ship's crew, and providing a comprehensive report of findings and corrective actions. Any cable renewals require specific repainting using government-furnished materials.
