Fiber Optic Cables

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 1.0db/km attenuation and 500 MHz/km bandwidth). Refer to Table C-2 for the minimum requirements of fiber optic cable.
