It is made for outdoor and long-distance use. OS1 supports speeds up to 10GbE. OS2 supports faster. In the intricate world of fiber optic cabling, selecting the right single-mode fiber (SMF) type is paramount for performance, reach, and cost-efficiency. The terms OS1 and OS2 frequently surface, often causing confusion. While both are single-mode fibers designed for long-distance, high-bandwidth. Fiber optic cables for outdoor applications are engineered to withstand the more demanding conditions seen outside, from environmental extremes to mechanical forces. These two categories define how light travels through the fiber core: Transmits a single light mode; very low attenuation; supports long-distance transmission up to 100 km or more. Unlike copper cables, which depend on electrical signals, fiber leverages light to convey.
