When my dad built our house a few years ago, he acquired this beefy network cable from some place that i do not know. It is grey and it has more shielding inside than normal cat5 cable. It infact has too much sheilding for it to fit into an rj45 connector. We dont use it for patch cables so that isnt a problem. My question is, what is it? Is it cat5? We use it as the wire for inside our walls and use normal patch cables to connect to computers.
