U/UTP (Unshielded/Unshielded Twisted Pair): Neither the individual twisted pairs nor the cable has any additional shielding built-in. Only the basic protections - the standard insulation around each twisted wire, and the cable sheath itself - are present In addition to the basic Ethernet cable standards and the stranded vs. solid designs, there are also other manufacturing specifications available for each type and category. These are commonly abbreviated as:

Crimping tools are used to join or connect two components or pieces of material through compression forces. They work by squeezing the two parts together tightly enough to form a fairly permanent bond or seal. Different sorts of crimp tools have various additional functions along with this ability to compress and seal materials. Common examples include cutting, stripping, and bending. A conventional enumeration of wire color pairs then begins blue (and white), orange (and white), green (and white) and brown (and white), which subsumes a color-coding convention used in cables of 4 or fewer pairs (8 wires or less) with 8P and 6P connectors. If you intend to make lots of cables, wiring them yourself can also be a considerable cost-saving measure With the advent of structured wiring systems and TIA/EIA-568 (now ANSI/TIA-568) conventions, the RJ61 wiring pattern is falling into disuse. The T568A and T568B standards are used in place of RJ61 so that a single wiring standard in a facility can be used for both voice and data. line series connection using 50-pin connector (with bridging adapter) ahead of customer equipment. Mostly used for call sequencer equipment.

As with all Ethernet and network cables, Cat5 cables (including Cat5e) typically use the RJ45 connector standard. Solid conductor (solid-core) Cat5/Cat5e Ethernet cable tends to be used where longer runs need to be set up to achieve a more reliable and stable permanent wired network. This is more common in office buildings and other professional setups. Applications that involve running outdoor Cat5 cable, or passing it through sections of wall, will often benefit from the use of solid-core wiring. Cat5 stands for Category 5 cable, while Cat5e stands for Category 5 Enhanced (or Enhanced Category 5). Cat5e specs offer a significant upgrade in terms of general performance and faster data transfer speeds than the earlier Cat5 versions. Knowing how to wire an RJ45 connector plug means that you can cut your Ethernet cable to custom lengths. This is handy for neatly managing cables or creating very long runsSee to the right for a Cat5e cable diagram, showing the basic construction of different types of Cat5e Ethernet cables.

In January 2001, the FCC delegated responsibility for standardizing connections to the telephone network to a new private industry organization, the Administrative Council for Terminal Attachments (ACTA). [4] For this delegation, the FCC removed Subpart F from the CFR and added Subpart G. The ACTA derives its recommendations for terminal attachments from the standards published by the engineering committees of the Telecommunications Industry Association (TIA). ACTA and TIA jointly published the standard TIA/EIA-IS-968, [6] replacing the CFR information. U/UTP is, therefore, the most susceptible to interference, signal noise, return loss, and attenuation, although the cable will be considerably cheaper to buy. F/FTP will offer the greatest protection against performance-limiting factors like crosstalk, but it will also be the most expensive type to buy. F/FTP (Foil/Foil Twisted Pair): Both the individual twisted pairs and the cable have an added layer of foil shielding around them Cat5 and Cat5e are two common classifications of Ethernet or network cabling. The Cat5e specification came into widespread use after 2001, before which Cat5 had been the latest standard. The conductors other than the two central tip and ring conductors are in practice variously used for a second or third telephone line, a ground for selective ringers, low-voltage power for a dial light, or for anti-tinkle circuitry to prevent pulse dialing phones from sounding the bell on other extensions.Modular Wiring Reference". Siemon. Archived from the original on 2010-10-08 . Retrieved 2010-10-14. Some telephones such as the Western Electric Princess and Trimline telephone models require additional power (~6 V AC) for operation of the incandescent dial light. This power is delivered to the telephone set from a transformer by the second wire pair (pins 2 and 5) of the 6P4C connector.

Ethernet cables come with RJ45 connectors on both ends. Because of this, an Ethernet cable is sometimes designated as an RJ45 cable. These cables are often used to connect computers onto Ethernet networks. The RJ45 connector resembles a six-pin RJ11 connector, though the 45 is slightly wider. Since each connector has eight pins, an RJ45 Ethernet cable will have eight wires of varying colours. RJ45 cables can be wired according to two different schemes, T-568 A or B, depending upon the devices to be connected within the network. Crossover patch cables have different wiring schemes on each end to support computer-to-computer connections.

At first glance, you cannot necessarily tell whether a given length of Ethernet cable is stranded or solid without cutting through it to find out. However, stranded cable is usually a lot more flexible than solid core cable. Solid cables will often retain some degree of deflection for a while after being bent at a sharp angle. Cat5e Cable Diagram In modern domestic and commercial environments, RJ45 connectors are primarily used for plugging an internet-enabled device directly into hardware such as a modem, router, or server. The connectors themselves are the modular sets of fittings at either end of the physical data connection (Ethernet cable) joining one networked device to another.
