Editing Category 5 cable (section)

== Standards ==
Category&nbsp;5 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).<ref>{{cite web |url=http://www.ense.be/PDF/2100.pdf |title=Additional Transmission Performance Guidelines for 4-pair 100&nbsp;v category&nbsp;5 Cabling |access-date=2013-05-12 |archive-date=2013-10-05 |archive-url=https://web.archive.org/web/20131005004127/http://www.ense.be/PDF/2100.pdf |url-status=dead }}</ref> These documents specify performance characteristics and test requirements for [[frequencies]] up to 100&nbsp;MHz.

The cable is available in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. [[Patch cable]]s are stranded. Permanent wiring used in [[structured cabling]] is solid. The category and type of cable can be identified by the printing on the jacket.<ref>{{cite web|url=http://donutey.com/ethernet.php |title=Ethernet Cable Identification and Use |publisher=Donutey |access-date=2011-04-01 |url-status=dead |archive-url=https://web.archive.org/web/20110710144347/https://donutey.com/ethernet.php |archive-date=2011-07-10 }}</ref>

The Category&nbsp;5 specification requires conductors to be pure copper. There has been a rise in counterfeit cables, especially of the copper-clad aluminum (CCA) variety.<ref>{{cite web|url=https://www.flukenetworks.com/content/application-note-copper-clad-aluminum-cables |title=APPLICATION NOTE Copper Clad Aluminum(CCA) Cables |date=26 December 2013 |publisher=Fluke Networks |access-date=2021-04-07}}</ref> This has exposed the manufacturers and installers of such fake cable to legal liabilities.<ref>{{cite web|url=https://cccassoc.org/2012/10/26/potential-legal-liabilities-for-manufacturers-and-installers-of-category-communications-cables-made-with-copper-clad-aluminum-conductors/ |title=Potential Legal Liabilities for Manufacturers and Installers of Category Communications Cables Made with Copper Clad Aluminum Conductors |publisher= Communications Cable and Connectivity Association, Inc.
