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 Cat5e cable spec dictates that it can carry data over a wired connection at speeds of either 10 Mbps, 100 Mbps, or 1000 Mbps (equal to 1 Gbps, and thus usually referred to as Gigabit Ethernet). You will often see this written as 10/100/1000 Ethernet. This means that if your local network (or incoming internet connection) runs at between 10-1000 Mbps/1 Gb (also known as a 1000BASE-T network), Cat5e Ethernet cable should be able to handle the required data throughput at full speed, with no loss or delay.
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. Compared to the CAT5 and CAT5e ethernet cables, the CAT6 cable offers dramatically higher speeds and a more stable, uninterrupted connection. In day-to-day practical terms, most users will chiefly be interested in what internet speeds or data transfer speed each standard support. Outer insulation is typically polyvinyl chloride (PVC) [27] or low smoke zero halogen (LS0H). [ citation needed] Example materials used as insulation in the cable [28] Acronym CIBSE (2000).

F/FTP (Foil/Foil Twisted Pair): Both the individual twisted pairs and the cable have an added layer of foil shielding around them 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.

The Category5e specification improves upon the Category5 specification by further mitigating crosstalk. [9] The bandwidth (100MHz) and physical construction are the same between the two, [10] and most Cat 5 cables actually happen to meet Cat 5e specifications even though they are not certified as such. [11] Category5 was deprecated in 2001 and superseded by the Category5e specification. [12] 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. Cat5 and Cat5e cable prices vary according to brand, quality, length, and materials, as well as the type and amount of any additional shielding included in the manufacture. The cheapest Ethernet cables in this category will generally be unshielded solid Cat5 varieties, while more expensive versions will usually be stranded and shielded Cat5e leads.
