At the core of every fiber network is the optical fiber itself. Our optical fiber portfolio spans standard G.652.D zero water peak fiber, G.654.D large effective area fiber for long-haul and submarine systems, and G.657.A1 and G.657.A2 bend-insensitive fibers — including 200 µm reduced-diameter variants for high fiber-count and micro-duct cables. Every fiber is engineered to ITU-T and IEC standards for low attenuation, precise geometry, and low splice loss, delivering reliable full-spectrum transmission from 1260 nm to 1625 nm across backbone, metro, access, FTTH, BharatNet, and data center deployments.
