Inside the ethernet cable, there are 8 color coded wires. Pull the cable off the reel to the desired length and cut. The ethernet cable,connectors and Connector Crimper are available at local computer store or most electrical centers. You must have some RJ-45 connectors, UTP cable, Rj-45 Modular Connector Crimper and a hand. How to wire your own RJ-45 Ethernet cable Note: It is very important that a single pair be used for pins 1 and 2 3 and 6, 4 and 5, 7 and 8. EIA/TIA 568A Ethernet UTP cable wiring diagram PinĮIA/TIA 568B Ethernet UTP cable wiring diagram Pin You may use either of them to crimp the Ethernet RJ45 network cable. There are two standards for network RJ45 cable wiring: EIA/TIA 568A and EIA/TIA 568B.
Category 6a cable is required to reach the full distance and category 6 may reach a distance of 55 metres. The line encoding used by 10GBASE-T is the basis for the slower 2.5GBASE-T and 5GBASE-T standard, implementing a 2.5 or 5.0 Gbit/s connection over existing category 5e or 6 cabling. Cables which will not function reliably with 10GBASE-T may successfully operate with 2.5GBASE-T or 5GBASE-T if supported by both ends. 10Gbit Ethernetġ0GBASE-T (IEEE 802.3an-2006) is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded twisted pair cables, over distances up to 100 metres. 1000BASE-T requires all four pairs to be present and is far less tolerant of poorly installed wiring than 100BASE-TX. The Gigabit RJ45 connection requires, at least Category 5 cable (the same as 100BASE-TX), but Category 5e cable (Category 5 enhanced) or Category 6 cable may also be used and is often recommended. Gigabit Ethernetġ000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over copper wiring. Like 10BASE-T, the active pairs in a standard connection are terminated on pins 1, 2, 3 and 6. 100BASE-TX runs over two wire-pairs inside a Category 5 cable or above. Fast Ethernet RJ-45 connected devices are generally backward compatible with existing 10BASE-T systems. The segment length for a 100BASE-T cable is limited to 100 metres. Fast Ethernetġ00BASE-TX (IEEE 802.3u) was introduced in 1995 and remained the fastest version of Ethernet before the introduction of Gigabit Ethernet. It runs on UTP data or optical fiber cable in a star wired bus topology, similar to 10BASE-T where all cables are attached to a hub. EIA/TIA specifies RJ-45 connectors - properly called 8P8C - (ISO 8877) for UTP (unshielded twisted pair) cable. Category 5 (CAT5), Category 5e or Category 6 (CAT6) cables are widely used, but other variations are available. Ethernet RJ45 connection and cableĪlmost every ethernet network use Unshielded Twisted Pair (UTP) cable ended with RJ-45 connectors.
Ethernet uses a bus (very old coaxial cable) or star topology (standard UTP cable equipped with RJ-45 connectors). Nowdays ethernet over twisted pair ( RJ-45 connection) runs at 10Mb, 100Mb, 1Gb or 10Gb per second. It was originally developed by Xerox Corporation in cooperation with DEC and Intel in 1976.
There are several specifications of Ethernet RJ-45 connection over twisted pair: oldest 10Mbit ( Ethernet), old but still used 100Mbit ( Fast Ethernet), modern 1Gbit ( Gigabit ethernet) or newest 10Gbit ethernet. Ethernet cable for any of those interfaces may be easily crimped by yourself.Įthernet is officially standardized by IEEE standard 802.3.
