Network cables, including Cat5, Cat5e, Cat6, Cat6a, etc., are twisted pair cables for carrying signals in structured cabling for computer networks such as Ethernet.
Can I use RJ11 for Ethernet?
First of all: Yes you can, but it won't make you happy. 10Mbit/s Ethernet uses 2 pairs and works quite well over short distances with the kind of cable shown, you just need to crimp an RJ45 plug on it (using the pairs 1/2 and 3/6).Jun 12, 2017
What is the difference between RJ11 and RJ45?
RJ45 is mostly used with Ethernet cables while RJ11 is connecting to telephone units. RJ45 has 8 wires inside while Rj11 has 4 wires. RJ45 is bigger in size than RJ11. You cannot plug-in the RJ45 cable connector into an RJ11 jack/interface/port/slot, however, you can do the opposite.Dec 8, 2020
What are the 4 wires in a phone line?
In a typical home, the telephone cables connecting your phones within you home contain four wires... red, green, yellow and black. They are used in pairs for each phone line you have. Repairmen in fact refer to the wires in terms of "pairs", so technically a standard four wire telephone line has two pairs.
What is difference between RJ11 and RJ12?
RJ11 is an older version of RJ12, and they are the same size. The difference is that RJ11 uses four internal wires (called conductors) while RJ12 uses six. RJ12 is backwards compatible with RJ11, but RJ11 will not work with RJ12.Dec 11, 2018
What is a telephone cord?

What is the difference between a straight and reverse cable?
Straight cables are used to send data, like a fax machine, while reverse cables are used for voice, like a telephone. On a straight cable, the wires will connect to the same metal pins on either side of the cable. Pin 1 to pin 1, pin 2 to pin 2, etc. On a reverse cable, the opposite is true.
How long is a 6 foot cord?
On average, 6 feet of uncoiled cord equals about 1 foot coiled. So if you order a phone cord labeled “6 feet” for length, it will be 1 foot coiled up all the way and stretch to about 3-4 feet. Coiled phone cords are generally made in four sizes: 6 feet (1 foot coiled; small), 12 feet (2 feet coiled; medium), 25 feet (4 feet coiled; long), ...
How many contacts does a RJ11 have?
On the inside, RJ11 will have four metal contacts for the internal wires inside the cable while RJ12 has six contacts. Since they are the same size, RJ12 is backwards compatible with RJ11. However, since RJ11 is the older of the two it is not compatible with RJ12.
Is a RJ22 the same as a RJ11?
RJ9 and RJ22 are two different names for the same thing. Being smaller than RJ11/RJ12, these connectors only have room for four metal contacts instead of six. The size of a coiled phone cord can be somewhat confusing. Most companies will list the size the cord would be if it was completely uncoiled.
What is a POTS cable?
Voice communication doesn’t require a lot of bandwidth, so the thin, flat phone cables you see in most homes are perfectly suited to what’s known in the telecommunications industry as POTS (which stands for “plain old telephone service”) connections. These cables normally contain stranded conductors made from 24AWG or 26AWG silver/satin or solid copper, which is more than enough to handle voice traffic and low-speed data like the signals sent to a fax machine. It’s an oversimplification, but as long as the cable comes from a quality manufacturer (like Cmple) all phone cable is generally the same.
Why are bulk phone cables not braided?
When you purchase bulk cable the wires are generally not twisted or braided, because there’s no real problem with signal loss at such low bandwidth. Some pre-made phone cables may have twisted pairs or shielding inside, although it’s usually not necessary. Phone cables are usually covered with a durable PVC jacket.
How many conductors are needed for a phone line?
Six conductors are needed for three phone lines, for some of the special features found on many modern phones, or for telephones connected in more elaborate powered phone systems. For those reasons, 6P4C and 6P6C modular connectors are used most often in the U.S., and they’re the most commonly-seen types of pre-made phone cables.
What does Ethernet cable look like?
Additionally, some Ethernet cables look exactly like phone cables and use similar connectors on each end; they’re very easy to confuse.
What does RJ stand for in phone?
There’s a long history to the abbreviation RJ (which stands for “registered jack”), and it’s really not correct to use the term to describe phone cables.
