Standards for cable distance recommend that Cat5, 5e, and 6 cables have a maximum cable segment run length of 100m or 328 feet.

Four pairs of twisted wires are used to construct Category 5, 5e, 6, and 6a cable, which is most commonly unshielded, as in UTP. The cable distance specifications are part of the Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA) standards. When recommended cable distances are exceeded, then signal loss may occur. If segment runs must exceed twisted-pair cabling specifications, a repeater or switch could be added. Solid cable, such as Cat5e solidcore cable, is normally used for covering longer network cable distances.

Category 5e Cable Length Recommendations

The recommended Cat5e cable length is similar to the standards for other twisted-pair cables. Cable distance guidelines for Cat5e are associated with TIA/EIA-568-5-A documentation. The maximum for a CAT5e cable segment is 100 m. Category 5 Enhanced cable supports up to 1000 Mbps (Gigabit) Ethernet speeds as four wire pairs are utilized.

Maximum Cable Segment Distances for Cat6 or Cat6a Cable

In 10/100/1000BASE-T applications, the maximum cable distance of a Cat 6 cable is 100 metres. However, Category 6 cable segment distance drops to a maximum run length of 55 metres when used for 10GBASE-T. This cable length may be further reduced in hostile alien crosstalk environments. These limits are not an issue with Cat6a cable. Augmented Category 6 cable’s maximum cable distance specifications are the same as Cat5 and 5e. This means 10GBASE-T can be supported at a 100-metre cable run distance.
