Category 3 cable, commonly known as Cat 3 or station wire, and less commonly known as VG or voice-grade (as, for example, in 100BaseVG), is an unshielded twisted pair (UTP) cable used in telephone wiring. It is part of a family of standards defined jointly by the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA) and published in TIA/EIA-568-B.
Although designed to reliably carry data up to 10 Mbit/s, modern data networks run at much higher speeds, and Cat 5e or better cable is generally used for new installations.

I have FiOS internet (200 Mbps up/down service), via an Ethernet cable entering my house from one of their ONT boxes outside. I would love to have it available at each of the wall plates in my house. When the Verizon tech did the install, he looked behind one of the wall plates and said "your hou...
I got this cable with a homeplug AV 200 device - its labelled cat 5e
But looking at the plug end has me rather dubious about it.
(There's only 4 strands there, not the standard 8 - and missing pins, so I suspect these cables are designed to do so. The wire jacket is also surprisingly loose)....
Category 1 cable, also known as Cat 1, Level 1, or voice-grade copper, is a grade of unshielded twisted pair cabling designed for telephone communications, and at one time was the most common on-premises wiring. The maximum frequency suitable for transmission over Cat 1 cable is 1 MHz, but Cat 1 is not currently considered adequate for data transmission (though it was at one time used for that purpose on the Apple Macintosh starting in the late 1980s in the form of Farallon Computing's//NetTopia's PhoneNet, an implementation of Apple's LocalTalk networking hardware standard).Although not an official...
