Amphenol Products from ShowMeCables
Amphenol, also called RJ21 or Cat3, is a type of telephone cable that can connect up to 25 telephone lines. These heavy-duty cables are used when setting up a telecom system, usually someplace like an office building. The amphenol cables are connected into another device, such as a Telco patch panel, which then accepts standard RJ11 lines for connecting directly to telephones. There is also a Cat5e version is that used the same way but for ethernet instead of phone lines.
