The twists are important because they help cancel electrical noise that is inherent in electrical cables. The biggest differences between these cables and telephone cables is the quantity of copper in the cable (the more the better) and the twists between the individual wires. Although RJ-45 and RJ-11 connectors are generally not compatible, there may be occasions when you can convert a cable with RJ-45 connectors to an RJ-11 jack. If you need to use a length of cable with RJ-45 connectors in an RJ-11 application, you can purchase an adapter. In theory, telephony cable can be used to support 10/100 connections (not Gigabit) over short distances.

RJ45 connectors can support 10Gbps over Ethernet, provided the other equipment like network cables also support that speed. Connect both ends of the cable the same to an RJ45 JACK (do not crimp ends on the cable), essentially we are going to substitute color pairs of the existing cable for "standard" color codes in EIA/TIA 568B color code. I can tell you right now you’re gonna throw this idea out the window as soon as your video games start glitching in the heat of a battle. Slide all the wires as far as possible into the connector so the insulation is flush with the rear of the connector. RJ12 connectors can be used in place of RJ11 because RJ12 has all the connectors RJ11 needs (plus 4 extra).However, trying to convert an RJ-11 to an RJ-45 adapter is ill-advised, since there aren't enough wires and telephone wire isn't designed to accommodate the digital signals used in network cables. They are used to connect a phone line with the key telephone system, small exchange-like systems used by businesses to connect to the carrier on the outside and create a network of phones and extensions on the inside.

If you can find a telephony cable that is not cut and is a "home run" between the two points you need to connect, and it contains at least 4 conductors, it may be possible. In fact, the RJ45(S) jack — as defined in the standardized spec — is rarely used, but the RJ45 commonly refers to any 8P8C modular connector used in computer networking (Ethernet). RJ-45 connectors are usually attached to a CAT-5 or Cate-5e cable with eight wires, commonly used in computer networking. Untwist the four pairs of wires and arrange them from left to right starting with the white-and-green wire, followed by the white-and-orange wire, the solid blue wire, the white-and-blue wire, the solid orange wire and the solid green wire.Using 8 contacts allows for greater bandwidth so RJ45 is used for data-intensive applications like Ethernet and can support bandwidth up to 10Gbps. To achieve a delay free use of your PS4, you will need a proper ethernet network cable installation(CAT5e, CAT6 or CAT6a). I have random RJ11 wires in house which have been cut off as they were used for the master socket and the master socket was in an awkward place.

Carefully cut off the solid brown and the white-and-brown wires so they're flush with the outer insulation. A registered jack (RJ) is a standardized network interface for connecting voice and data telecommunications equipment. Making a cable for your DSL modem using both RJ-45 and RJ-11 connections allows you to save money and use as little or as much CAT5 cable as you need for your project.If you cable is Red/Green Yellow/Black, connect the green to Pin 1, the Red to pin 2, the black to pin 3 and the yellow to pin 6, do the same on both ends and connect with a standard patch cable to the router and computer. I am assuming you use it for gaming and video streaming and you would like to enjoy a delay free experience. All three jack types are used to connect phones—for one-, two-, and three-line service respectively. RJ14 is similar to RJ11 but is wired for two phone lines; it uses a 6P4C configuration where 4 connectors out of the 6 positions are used.
