![]() This is designed solely for outdoor use, with reinforced armoured models suitable for use below ground.Having got the cable I ordered, one of the first things I wanted to do was to make up a good ~6m cable for my 1-Wire AAG/Dallas weather station. The CW1128 is an additional BT telephone cable specification. This resists not only weather but also UV (ultraviolet) light. LSOH insulation will emit neither fumes nor halogen in the event of a fireĪ variation of the standard, the CW1308B, has reinforced insulation for use both outdoors and indoors. If mixed with water it will form hydrochloric acid. It can cause breathing difficulties and lung damage if inhaled or skin burns if touched. Hydrogen chloride - a halogen, or salt-producing chemical element - is another dangerous gas emitted by some types of PVC when it burns or melts. LSOH or LSZH (low smoke zero halogen).Conventional PVC emits thick black smoke and hazardous (Halogens) fumes when it burns or is exposed to high temperatures and this can interfere with attempts to escape in the early stages of a fire. This refers to the insulation’s resistance to fire. The insulating sheath is normally PVC, but you may also see: These are known as the CW1308 standard.Ĭables made to the BT specification typically feature paired 0.5mm insulated copper conductors, but the number can vary hugely, from as little as 2 to as many as 200. Here in the UK, BT has established a number of commonly used telephone cable specifications. These heavy-duty cables are mounted on utility poles and are especially popular in North and South America ![]() Overhead telephone cabling is used outdoors for voice, data and even TV signals.It is used in domestic and commercial settings in the UK and around the world The RJ11 telephone cable is an international standard and the best option for connecting single telephone lines to single devices.Straight cords feature an exactly duplicated arrangement of wires to pin connections on either side of the cable, while in reverse cables, the order of connections is mirrored i.e. The first type is principally used for data, while reverse cords are for voice services. It can be longer than it appears - for example, a one-foot length of coiled cabling might be six feet in length when uncoiled Coiled cable uses a separate connector to the main phone line, typically a smaller RJ9 or RJ22. The former connects telephones to wall sockets while the latter is the familiar coiled cabling used to connect receivers to a landline handset. Internal/external cabling is the most versatile option and can be used both indoors and outdoors. Telephone cabling designed for external use is thicker and designed to be weatherproof, while internal cabling is more flexible and can be used in a variety of locations. There are three broad types - internal, external, and internal/external. You can even hook up an ethernet cable to a phone jack, provided that the modem is connected to a wall socket using an actual ethernet cable. Ethernet cables, which provide high-speed data connections between PCs, are a modified form of telephone cabling with a high capacity RJ45 connector.Įthernet cables are used to create LANs (Local Area Networks). ADSL is used to provide internet access to business and domestic consumers.Īlthough wireless networking technology is now largely familiar, wired networking still has its place in office environments or locations where Wi-Fi reception is poor, for example. This stands for asynchronous digital subscriber line, meaning the upload speed is slower than the download speed. ![]() It can be delivered alongside standard landline telephony because DSL operates at a higher frequency. These include:ĭSL is used to transmit data along telephone lines. What is phone cable used for? You might think the answer is straightforward - telephones! Of course, they are central, but this type of cabling also has other uses.
