Enabled by a truly bend-insensitive fiber, this rugged drop cable can be bent to a minimum bend radius of 5 mm (0. 2 in) and be directly stapled to wall studs and rafters with standard cable staples and hardware-store variety staple guns. In 2026, choosing between OS2, OM3, OM4 and OM5 is no longer just a “speed vs distance” question. AI clusters, FTTH/FTTR, 400G/800G optics and ESG targets all push projects toward the right combination of single-mode and multimode fiber — especially low-loss OS2 and bend-insensitive G. OS2. Bending losses are a function of the fiber type (SM or MM), fiber design (core diameter and NA), transmission wavelength (longer wavelengths are more sensitive to stress) and cable design. Among these, commonly used standards are G. This article intends to provide a clear explanation of G. Nevertheless, the specific use in an optical access network puts different demands on.
