Fiber Optic Cables Installation Guide for the Model FS518 Fast Ethernet Switch In North America, use EIA-569-A horizontal 62.5/125 µm multimode optical fiber cable (ANSI/EIA/TIA-492AAAA). Internationally, use ISO/IEC 11801 62.5/125 µm multimode optical fiber cable (IEC 793-2 type A1b, with 1.0 db/km attenuation and 500 MHz/km bandwidth). Refer to Table C-2 for the minimum requirements of fiber optic cable. Fiber Cable Specifications Table C-2 lists the electrical requirements of fiber cable. Table C-2.
