What is a 8P8C connector?
Nearly always, 8P8C modular connectors (often referred to incorrectly as RJ45 connectors) are used for connecting category 5 cable. The cable is terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be mixed in an installation so long as the same scheme is used on both ends of each cable.
What is an RJ 45?
The RJ (registered jack) prefix is one of the most widely (and incorrectly) used prefixes in the computer industry; nearly everyone, including people working for cabling companies, is guilty of referring to an eight-position modular jack (sometimes called an 8P8C) as an RJ-45.

Originally posted by: Snuffaluffaguss. Networking Forum would have better answere, but a cat 5 jack uses 4 wires (two pair) for data. its Pins 1,2,3,6, Pins 4,5,7,8 have no data sent on them but they are important because they eleminate cross talk.
What are the numbers in a cable?
1, 2, 3 and 6 are used in a typical cable.
How many wires do I need to run 100 Mbps?
If you're running 100Mbps, you'll need all 8, but you can run at 10Mbps using 4 of the 8 wires. As stated earlier, it's best not to mix data and phone on the same cable. You might get interference that way, plus it's just bad practice. There is voltage on phone wire and when the phone rings, it jumps up substantially (low current though). I suggest going to your local Home Depot and buying some CAT5 and running what you need to network your place. They can hook you up with everything you need.

What is the purpose of wire twists in Cat5e?
The purpose of the wire twists found in Cat5e cable is to significantly reduce the crosstalk and its side effects. Similarly, Electro Magnetic Interference (EMI) is an unwanted signal that is induced into the cable. The difference is that EMI is typically induced from a source that is external to the cable.
What is the difference between EMI and Cat5e?
The difference is that EMI is typically induced from a source that is external to the cable. This could be an electrical power cable or device, or in some cases adjacent Cat5e cables that do not adhere to the 568A and 568B standards.
What is 568A cable?
The 568A wiring pattern is recognized as the preferred wiring scheme for standard because it provides backward compatibility for both one pair and two pair Universal Service Order codes (AT&T) USOC wiring. U.S. Government regulations require the use of the preferred 568A standard for wiring installed under federal contracts. However, N-TRON adopted the 568B standard since it is the most widely used in the industry today. It matches the older AT&T 258A color code. It is also approved by the ANSI/TIA/EIA standard. This scheme provides one pair for backward compatibility to the USOC wiring scheme. This illustration will assist you in identifying the differences between the 568A and 568B color schemes. The difference between the two schemes is that the orange and green pairs are interchanged as shown here. These standards specify a maximum segment length of 100 meters (328 feet) between two devices. This length includes patch panels and cables. When longer distances are desired, the use of switches, repeaters, or fiber optic media may be required.
How to connect two Ethernet switches together?
Two Ethernet switches may be connected together with a standard patch cable as long as both devices are compliant with the MDIX standard. N-TRON Ethernet switches use this technology on all 10/100 RJ45 ports. Basically, the MDIX standard automatically performs the crossover functions without user configuration. It allows the switch to properly align the conductors internally. In some situations, connection of similar devices such as legacy hubs or Network Interface Cards (NIC's) may be accomplished by the use of a cross-over cable. Therefore, the cable itself will physically perform the crossover function. A crossover cable can be easily created by using the 568A scheme at one end and the 568B scheme at the other end as shown in the 568A-568B illustration below.
What color code is used for RJ45 plugs?
Both the 568A and 568B are the two color code schemes used to correctly wire the RJ45 eight-position modular plugs. These two color codes are approved by the American National Standard Institute/Telephone Industry Association/Electronics Industry Association (ANSI/TIA/EIA) wiring standards. There is no difference, whatsoever, between the two wiring schemes, in connectivity or performance when connected form one device to another, so long as the devices are wired for the same scheme. The only time when one scheme has an advantage over the other, is when one end of a segment is connected to a modular device, and the other end to a punch block. In which case, the 568A has the advantage of having a more natural progression of pairs at the punch block side.
What is cross over cable?
It allows the switch to properly align the conductors internally. In some situations, connection of similar devices such as legacy hubs or Network Interface Cards (NIC's) may be accomplished by the use of a cross-over cable. Therefore, the cable itself will physically perform the crossover function.

Cat 5 is also used to carry other sign…
Standards
The specification for category 5 cable is defined in ISO/IEC 11801, IEC 61156 and EN 50173.
The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These documents specify performance characteristics and test requirements for frequencies up to 100 MHz.
The cable is available in both stranded and solid conductor forms. The stranded form is more fle…
Variants and comparisons
The category 5e specification improves upon the category 5 specification by revising and introducing new specifications to further mitigate the amount of crosstalk. The bandwidth (100 MHz) and physical construction are the same between the two, and most Cat 5 cables actually meet Cat 5e specifications, though they are not specifically certified as such. The category 5 was deprecated in 2001 and superseded by the category 5e specification.
Applications
Category 5 cable is used in structured cabling for computer networks such as Ethernet over twisted pair. The cable standard prescribes performance parameters for frequencies up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T (Gigabit Ethernet), 2.5GBASE-T. 10BASE-T and 100BASE-TX Ethernet connections require two wire pairs. 1000BASE-T and faster Ethernet connections require four wire pairs. Through the use of power over Ethernet (PoE), power can …
Characteristics
The use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and crosstalk from other pairs.
Outer insulation is typically polyvinyl chloride (PVC) or low smoke zero halogen (LS0H).
Most Category 5 cables can be bent at any radius exceeding approximately four times the outside diameter of the cable.
