These are maximum suggested cable lengths. For more specific Ethernet wiring rules, refer to

ANSI/TIA/EIA Std 568-B.1.

For fast Ethernet, low noise, high-performance 24 AWG cables and

connectors are highly recommended. Any degradation in noise rejection will degrade an entire link

between a switching device and the peripheral equipment.

For Gigabit operation, the increase in speed also increases the potential for data corruption by electrical

noise, and requires additional attention to the cabling layout of the installation. Cat6 data cable is

recommended for use with Gigabit Ethernet for higher noise immunity. Be aware of distance constraints

for multimode fiber as it is typically no more than 550 meters (about 600 yds) for Gigabit Ethernet. This

is compared to 2 km (1 mi) or more for 100-Mbps Ethernet.
