Flat phone cables are a type of charging cable that have a unique flat design, as opposed to the traditional round cables. These cables are available in a range of lengths and colours, and are compatible with most smartphones and other mobile devices. The flat design of these cables makes them more durable and less prone to tangling than traditional cables, making them a popular choice for those who are always on-the-go. Additionally, the flat design also makes them easier to store and less likely to get tangled in a drawer or dustbin.

Frequently Asked Questions (FAQs)

1. Are there different types of telephone cables?

Telephone wire comes in two gauges, 22 gauge and 24 gauge; 24 gauge is today's standard. There are two types of common modular plugs; the RJ-11 and RJ-14. The most common is the RJ-11, which uses only two of the telephone wires in a four (or more) strand wire.

2. Are all telephone line cables the same?

Here in the UK, BT has established a number of commonly used telephone cable specifications. These are known as the CW1308 standard. Cables 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.

3. What are regular telephone cables called?

One of the most common telephone cables is called the coaxial cable. It is called coaxial because it has one physical channel, which is an insulated layer that is a woven shield of copper.

4. What is the cable called from phone socket to router?

If you need an extension cable, use a good quality DSL cable (also known as ADSL cables) to connect your router to the phone master socket. Your SSE broadband pack includes one of these cables. Remember – using a longer extension cable may affect your broadband speed.
