Yes — programs such as BEAD (Broadband Equity, Access, and Deployment) include Buy America requirements that generally mandate the use of domestically produced iron, steel, manufactured products, and construction materials, which can encompass fiber optic cable. Waivers are available but require agency approval, and the rules are evolving, so grant recipients should review program-specific guidance carefully.

Single-mode fiber carries a single light wavelength over long distances with low signal loss, making it standard for carrier and long-haul networks. Multimode fiber supports multiple wavelengths over shorter distances and is common in data centers and campus networks. Both fall under NAICS 335921, but they are specified differently in procurement contracts and may be classified under distinct HTS subheadings, affecting duty treatment.
