The four wire pairs in the cable are color coded with 4 colors; namely, green, blue, orange and brown. Four wires in the cable have solid coloration, while the other four are a combination of these colors, painted in stripes onto a white background. These four pairs are twisted together and housed in a single jacket. The specific ordering of the colors differs, in accordance with the scheme employed. There are two color code standards; namely, the EIA/TIA 568A and EIA/TIA 568B, which are used to terminate the cable at the RJ45 ends (Nikkel).
Between similar devices, such as a PC to PC connection, a crossover cable would be required. Hence in this case, one end would employ the 568B standard, whereas the other end must utilize the 568A standard. When unlike devices are required to be connected, like a PC card to a hub, a straight through cable is used. In this case, both the RJ45 connectors comply with the same color code standard, either 568A or 568B (Nikkel).
First, the covering sheath of the cat 5 cable at the end is to be removed. Then, the pairs are to be untwisted and the colored wires are to be arranged, as per the required 568A or 568B standard. This is shown in the image appended below:
After this the individual wires are to be trimmed and inserted into the RJ45 connector, ensuring that all the wires are properly placed inside the connector. Thereafter, a crimping tool has to be employed, in order to fasten the cable to the connector. The length of the wire is to be minimized to the extent possible, as longer wires tend to decrease the transfer speeds. A similar procedure is to be followed at the other end of the cable, in order to obtain an Ethernet cable.
The CAT 5e Ethernet cable offers a fast and reliable way of transferring information between network cables. However without the use of an amplification device they can only be used up to a length of
