Summary

  • Depending on where the telephone cable is to be laid, a distinction is made between underground cable, field cable, aerial cable and long-distance cable. Accordingly, telephone cables are laid in different ways.
  • The designation of the telephone socket or telephone plug shows you which telephone cable is compatible with your device. A TAE telephone socket, for example, is labelled NFF or NFN. This means that a telephone cable with the mark F is the right one for you.
  • Characteristics such as the number of wires or the materials used, such as copper or glass fibre, provide information about the performance of the telephone cable.

The Best Telephone Cable: Our Picks

Guide: Questions you should ask yourself before buying a telephone cable

What are the advantages and disadvantages of a telephone cable compared to a DSL connection?

DSL telephone connection cable

A DSL connection socket (TAE) bundles the connections for telephone, Internet and other devices, such as a modem or fax.

Advantages
  • Is available almost nationwide
  • Greater choice between several providers
Disadvantages
  • Speed is very much dependent on location

Telephone connection cable

The telephone connection cable is a multimedia socket connection. The cable network providers accordingly offer connections for television, internet with telephone and radio.

Advantages
  • High transmission rates possible
  • TV, radio, internet and telephone connections available
Disadvantages
  • The cable's performance may be reduced if several subscribers share the bandwidth
  • The binding depends on the local network providers.

As a rule, cable internet achieves higher speeds than DSL technology. The speed with a DSL connection becomes slower if the house connection is further away from the distributor. Nevertheless, the DSL connection can send data up to four times faster than the cable internet.

How does the telephone cable differ from a CAT cable?

When looking for the optimal cable connection for your telephone, speed is a decisive criterion. CAT cables are divided into CAT 5, 5e, 6, 6a and CAT7. The term CAT describes the performance class of network cables. The performance class also tells you which operating frequencies and transmission speeds the cable is suitable for.

CAT 5 and CAT 5e are the most commonly used. The CAT7 cable, however, offers extremely high speeds and is therefore also suitable for professional use. The disadvantage, however, is that it is very expensive and the performance depends on the hardware used.

The telephone connection cable connects the telephone to the telephone socket (TAE socket). The telephone line is laid from the house connection to the telephone socket. Usually only four wires are needed for this cable. However, if you want to install more telephone sockets in the house, you must also pay attention to the number of wires and how you have to connect them.

How do you lay a telephone cable?

If you are the owner of a house and you may have tenants, it is not advisable to ask the tenant to lay the cable. Instead, you can ask an electrician to do it. However, it is also advisable to commission a network operator (Telekom, Vodafon, Unitymedia, etc.) and have them lay the cable.

Did you know that the longest phone call in the world lasted exactly 40 hours?

Two people from Hamburg, together with Alice and Radio Hamburg, set the world record in 2010. As a thank-you, they were given a free telephone connection for as long as they wanted. This means that nothing will stand in the way of the two of them continuing to make phone calls in the future.

What does a telephone cable cost?

You can get a telephone cable for about ten euros. However, there are high-quality cables for over 20 euros.

Decision: What types of telephone cables are there and which is the right one for you?

You've probably bought a new telephone and only noticed when you get home that the telephone connection cable is missing, or you've moved into a new building and have to set up the telephone line again.

Before buying a telephone cable, the question quickly arises: What types of telephone cables are there? What do I have to consider for the cable? What is the difference between telephone cable and data cable?

On our website, we would like to help you in your decision-making process to buy a telephone cable and show you what you should look out for when buying. In the following, we will show you what types of telephone cables there are. Depending on where the cable is to be installed, there are the following types:

  • Underground cable
  • Aerial cable
  • Field cable

Underground cable

The underground cable has the advantage that it is laid underground and is therefore protected from the weather, which reduces major damage. However, it has the disadvantage of requiring a lot of maintenance due to the fact that it is usually more difficult to locate.

Aerial cable

Aerial cable, also called self-supporting cable (SETRA), is usually fixed to overhead line poles. A further distinction is made between aerial cable and suspension cable. The main difference lies in the strain relief. In aerial cables, the strain relief is integrated in a cable sheath in a round symmetrical way, whereas in suspension cables, the strain relief is integrated in the cable sheath as a single cable.

Field cable

The field cable was used by the German Armed Forces for a long time, but they have already switched to fibre optic cables. However, the field cable is still used in civil defence and disaster control, but also by the German Federal Agency for Technical Relief. The three types are subordinated to the term local cable. In addition to the local cable, there is also the long-distance cable.

Long-distance cable

The long-distance cable differs from the local cable mainly in the handling of message traffic, which takes place between different exchanges.

What should I look for when buying a telephone cable?

When buying a telephone cable, it is important to know whether your telephone is analogue or ISDN. You can then choose the right cable accordingly. When buying an analogue telephone, make sure that you do not mix it up with other accessories, such as fax or answering machine cables.

The TAE telephone socket is usually marked NFF or NFN. This means that you need an F-coded cable. Therefore, look for the F symbol when buying the telephone cable.

Purchase criteria: You can use these factors to compare and evaluate telephone cables

In the following, we would like to show you which factors you can use to compare and evaluate telephone cables. This will make it easier for you to decide whether a certain product is suitable for you or not. The criteria you can use to compare telephone cables include:

  • Thickness of the cores
  • Number of cores
  • Shielding of the telephone cable
  • Copper or fibre optic cable
  • Signal attenuation
  • Different types of telephone (connection) cable

In the following paragraphs, we will explain what is important in each criterion to help you make your purchase decision.

Thickness of the wires

The longer the cable, the thicker and wider the wires should be to ensure the best possible transmission quality.

Number of cores

Basically, the more cores the cable has, the better the performance. Some cables have up to eight cores. For an analogue telephone, however, two wires are sufficient. For an ISDN connection, however, at least four cores are necessary. However, it makes sense to use four cores for the analogue telephone.

Shielding the telephone cable

The shielding protects the cable from damage and sources of interference. You can tell which type of shielding is used by the designation of the telephone cable. In principle, a distinction is made between J-Y(St)Y and J-YY cables.

  • J-Y(St)Y: Is a reliable type of shielding and can therefore be laid closer to interfering lines.
  • J-YY cable: This cable has no shielding and must therefore be laid far away from interfering lines or sources of interference. However, the cable offers you good voice quality.

When buying a telephone cable, make sure that it has good shielding. Materials such as PVC (polyvinyl chloride) are mainly used for shielding.

Copper or fibre optic cable

You can buy telephone cable as copper cable or fibre optic cable. The copper cable is cheaper than the fibre optic cable, but has a limited data rate. With fibre optic cable, the shielding is more reliable and the data rate is higher. If you want to buy a long telephone cable, the fibre optic cable is more suitable. The type of wiring enables you to transmit larger data packets. The data is therefore transmitted without interference.

Signal attenuation

The disadvantage of the telephone cable is that the longer it is, the greater the signal loss. The longer the cable, the more likely it is that the signal transmission will be reduced. This is also called signal attenuation. The person you are talking to cannot hear you properly when you are on the phone. For this reason, you should consider what length of cable is appropriate for your home or office before buying.

Diversity of telephone (connection) cables

When buying, you should keep in mind that the type and use of telephone cables varies from country to country.

Facts worth knowing about the topic of telephone cables

What is a telephone cable?

The telephone cable is a cable for the telephone line and is also called the telecommunications cable or main cable .

Did you know that horses don't eat cucumber salad?

The curious statement "The horse does not eat cucumber salad" was, along with "The sun is made of copper", the first sentence spoken by Philipp Reis on 26.10.1861 in his invention, the "telephone".

How can you extend a telephone cable?

You can buy a TAE extension cable, for example. When buying one, look at the name of the cable and the labelling of the telephone socket to find the right extension cable.

Why do telephone cables get tangled?

Perhaps you mean telephone cord synonymously with a telephone cord. For example, you pick up the handset with your right hand and reach over to dial. During the call, you hold the handset alternately with your right and left hand. The cord twists in the process.
