This document provides information on Ethernet connection standards including cable types, connector types, and maximum distances. It lists standards for copper and fiber cables ranging from 10 Mbps to 10 Gbps, noting the cable type (e.g. Cat5, fiber), connector used (e.g. RJ-45, SC), and maximum distance supported. It also provides details on common copper cable categories, their uses and supported speeds.

9. » Speed and throughput 10Mbps to 1Gbps
» Very low cost
» Cable lengths varies (1M – 100M)
» Short cables are referred to as “patch cords”
» Consists of 4 twisted pairs using 8 wires
inside outer jacket (orange, green, blue, brown)

10. » Cat 1 – Telephone wire – not for data
» Cat 3 – Used in 10BaseT (up to 10Mbps)
» Cat 5 – Data speeds up to 100Mbps
» Cat 5e – Data speeds up to 1Gbps (using 2-pair)
» Cat 6 – 4 pairs of 24-gauge copper wires (up to
1Gbps)
» Cat 6a – Enhanced performance in high noise
environments (up to 10Gbps)
» Most common – Cat 1 (Telephone) Cat 5, 5e, & 6
