F/FTP (Foil/Foil Twisted Pair): Both the individual twisted pairs and the cable have an added layer of foil shielding around them For home users, a CAT5e cable should be sufficient for all your networking needs. However, if you’re setting up a commercial network CAT6 cabling is a must. It is faster, more efficient, and will result is less network downtime due to its superior quality.
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), and 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 be carried over the cable in addition to Ethernet data. Cable twisting length is not standardized, but typically there are 1.5-2 twists per cm in Cat-5(e) and 2+ twists per cm in Cat-6. Within a single cable, each colored pair will also have different twist lengths based on prime numbers so that no two twists ever align. The amount of twists per pair is usually unique for each cable manufacturer. As you can see in the above picture, no two pairs have the same amount of twists per inch.

Its inner film enhances the already weatherproof UV Resistant PE sheath and keeps away any condensation that may build up. Suitable for burying underground mounting to buildings or installing indoors the 6mm copper cable is flexible and easy to install delivering upto gigabit speeds (subject to your network). As with all Ethernet and network cables, Cat5 cables (including Cat5e) typically use the RJ45 connector standard.The Evolution of Copper Cabling Systems from Cat5 to Cat5e to Cat6" (PDF).

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. Our kenable Cat5e FTP outdoor cable is designed with FULL COPPER 24AWG twisted pairs and is Foil Shielded to ensure any interference is kept under control it also has a drain wire so can be earthed! F/UTP (Foil/Unshielded Twisted Pair): While the individual twisted pairs do not have any additional shielding, the cable features an added layer of foil under the outer sheath ANSI/TIA/EIA-568-B.2-2001, Commercial Building Telecommunications Cabling Standard" (PDF). p.6 ¶4.3.2.

Please note:
It has been suggested that this section should be split into a new article titled Twisted pair, because Applies not only Cat 5, but to all communication cabling. ( discuss) ( June 2023) Cat5 cable specifications dictate it should be able to handle data transfer over Ethernet networks at frequencies (also known as bandwidth, or data-carrying capacity) of up to 100 MHz. Cat5e offers superior performance and is rated for frequencies of up to 350 MHz. This is due in part to its stricter performance requirements for things like crosstalk (interference between individual wires), attenuation and return loss.
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. Some cables are "UV-rated" or "UV-stable" meaning they can be exposed to outdoor UV radiation without significant degradation. [40] Cat5 is also used to carry other signals such as telephony and video. [17] In some cases, multiple signals can be carried on a single cable; Cat5 can carry two conventional telephone lines as well as 100BASE-TX in a single cable. [18] [19] [20] [21] [22] The USOC/RJ-61 wiring standard may be used in multi-line telephone connections. Various schemes exist for transporting both analog and digital video over the cable. HDBaseT (10.2 Gbit/s) is one such scheme. [23] Characteristics [ edit ]

Category5 is currently defined in ISO/IEC 11801, IEC 61156 and EN 50173, though it was originally defined in ANSI/ TIA/EIA-568-A (with clarification in TSB-95). [5] These documents specify performance characteristics and test requirements for frequencies up to 100MHz. U/FTP (Unshielded/Foil Twisted Pair): The individual twisted pairs each have their layer of additional foil shielding around them, but the cable only has the basic outer sheathing The Category5 specification requires conductors to be pure copper. There has seen a rise in counterfeit cables, especially of the copper-clad aluminum (CCA) variety. [7] This has exposed the manufacturers and installers of such fake cable to legal liabilities.

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.

However, there are valid use cases for choosing longer runs of Cat5e wiring, in which case you can easily buy reels in lengths of 1000ft or more. Common pre-cut lengths you will see on sale at UK suppliers include 30cm/300mm, 50cm/500mm, 1m, 2m, 3m, 5m, 10m, 30m, 100m, 152m, and 305m. Like all previous ethernet cables, the CAT6 cable ends with an RJ-45 connector. At this point, there is no indication that future generations of ethernet cables will use anything different. Since there is no outward difference between generations of ethernet cables, CAT6 cables can be identified by text that is printed on the insulation sheath.
Cat 5E cables are most commonly utilized with unshielded twisted pairs (UTP). However, environments with large motors, generators, and certain types of high-voltage lighting are major sources of Electromagnetic and Radio Frequency Interference (EMI/RFI). In these applications, shielded twisted pair (STP) cable will help protect data signals when connected properly. APPLICATION NOTE Copper Clad Aluminum(CCA) Cables". Fluke Networks. 26 December 2013 .
