Fiber Optic Cables

In North America, use EIA-569-A horizontal 62.5/125 m multimode optical fiber cable
(ANSI/EIA/TIA-492AAAA).
Internationally, use ISO/IEC 11801 62.5/125 m 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.
