Corning 012EN4-T4S01A20 – Gel-Filled Loose Tube Cable, Single-Mode OS2, Black, Outdoor ADSS, 12-Fiber

This 12-fiber gel-filled loose tube cable is designed for outdoor self-supporting aerial (ADSS) deployments, offering high-performance single-mode (OS2) transmission. The dielectric central element and black polyethylene jacket provide mechanical protection and environmental durability, while the gel-filled buffer tube ensures moisture resistance and long-term reliability. Each fiber is color-coded according to Telcordia standards for easy identification, with water-swellable tape providing additional protection against water ingress. Supporting 1310, 1383, and 1550 nm wavelengths with ultra-low attenuation, this cable is suitable for long-distance single-mode applications. Its robust tensile strength, nominal outer diameter, and optimized bend radius allow safe installation and operation under a variety of aerial span conditions.
