Web(OS stands for optical single-mode.) With only a single wavelength of light passing through its core, single-mode fiber realigns the light toward the core center instead of simply bouncing it off the edge of the core as multimode does. OS1 is applied to inside-plant tight-buffered cable, whereas OS2 is applied to loose-tube cables.
