Crimping an RJ45 Connector Correctly
Proper Wiring For Ethernet Cat5/Cat5e Cables
Cables can transmit information along their length. To actually get that information where it needs to go, you need to make the right connections to an RJ45 connector.
Your cable run needs to terminate into a connector, and that connector needs a jack to plug into.
Registered Jack 45 (RJ45) is a standard type of physical connector for network cables. RJ45 connectors are commonly seen with Ethernet cables and networks.
Modern Ethernet cables feature a small plastic plug on each end of the cable. That plug is inserted into RJ45 jacks of Ethernet devices. The term "plug" refers to the cable or "male" end of the connection while the term "jack" refers to the port or "female" end.
T568A and T568B are the two colour codes used for wiring eight-position modular plugs. Both are allowed under the ANSI/TIA/EIA wiring standards. The only difference between the two color codes is that the orange and green pairs are interchanged.
There is no transmission differences between T568A and T568B cabling schemes. North America's preference is for T568B. Both ends must use the same standard. It makes no difference to the transmission characteristics of data.
T568B wiring pattern is recognized as the preferred wiring pattern.
