Non-metallic, or NM, cable is the most typical type of wire used in homes. Romex cable, the most well-known brand name for this kind of electrical wire, is another name you might be familiar with.
Choose high-quality materials:
Electrical wires and cables are often made of copper and aluminum. However, while selecting wires for your property, you should only select copper cables. Moreover, choose multi-stranded wires as opposed to single-stranded wires.
Telephone cable that looks flat and is only used for telephones, fax machines, and some modems. It is made of copper wire strands that are twisted together in pairs of two. These cables, which are often grey, connect to phones and wall jacks using "RJ-11" connections (or the less common RJ-12, RJ-14, and RJ-25).
48 VDCIn certain nations, 50 VDC is used; in the United States, 48 VDC is applied to the line to drive the phone. Remember that a unique characteristic of telephones is that the signal line doubles as the power supply line.
It is possible to mistake telephone and Ethernet cables for one another due to their similar appearances. The size of the plastic connectors on the ends of the cable is the primary distinction between the two. While Ethernet utilizes an RJ45 connector, telephones use an RJ11/RJ12 connector. RJ45 has 8 pins, whereas RJ11/RJ12 only require 4-6 pins.
Cat 6 is usually more than sufficient for household use. You will receive 10 Gbps because the cable lengths will not readily exceed 37 meters. For your home network, the 250 Mhz bandwidth is more than sufficient.
The "RJ" in RJ45 refers to Registered Jack, a standard identification that dates back to the Bell System's Universal Service Ordering Code (USOC) protocol for telephone interfaces in the 1970s.
There are four distinct twisted pairs in CAT5 cable. For your phone connection, use the two wires in one of those pairs. The reason why 10/100 base T Ethernet employs the green and orange pairs is so that the blue and brown pairs can still be used for phones.

The device that links your internet service provider, or ISP, to your home network is called a modem. A router is a device that connects your wired and wireless devices to the internet simultaneously and enables direct communication between them.
