From your home to the operator, your connection goes through numerous cables and equipment. Whether by cable, DSL, fibre or even 4G, there is a part that can be at home (except for 4G and more) but also a part shared between several customers of the operator before arriving on his network.

In the case of a cable TV connection, your modem is first connected to a socket that can be fitted with an amplifier. It then passes through a so-called coaxial cable going either on the front or in a box on the street. This is often your responsibility. Even if it is placed by the operator, it is in your home and it is therefore up to you to keep it in good condition. However, if there are any concerns, this will be an item that can be checked by the operator.
Front connection from the guide first
However, you should know that the signal from a cable internet connection arrives at all the sockets connected to the same coaxial network. This also means that from this moment you share a certain bandwidth between the users of your building, your street or your neighbourhood depending on the number of subscribers in the said zone.
- The signal ends up reaching a device where it passes through optical fibres and is in the operator’s network to the devices allowing connection to the outside.
- We already find ourselves here with several places that could suffer from problems; the coaxial part, the equipment for switching from the coaxial to the fibre, the fibre and the operator’s equipment whether it is from a physical point of view but also quite simply of bandwidth available on one part of the journey.
You have 200 Mbit / s. There are 5 of you in your zone to have this speed. You are then connected to an optical fibre offering 1 Gbit / s. No problem; 5 times 200 = 1 Gbit / s. You then join a device where 10 fibres of 1 Gbit / s arrive. All 10 fibres have the same thing; 5 users. But towards the operator, there is only 5 Gbit / s. If all 50 users fully use their connections, this will not work. All users will then only have 100 Mbit / s. This problem will only concern those passing through this too small optical fibre. All the others of the operator will not be affected unless the same case occurs everywhere of course.
