ᐅ General: Network, TV cable, bus system

Hello dear community,

we are planning to buy a house, preferably an energy-efficient House 55. To be clear, we are still searching and currently have nothing fixed.

However, I am already thinking a lot about topics such as the home network, home bus system, and TV wiring. I have searched a lot online, but many questions remain. I now have some questions and hope you can help me with your experience:

Home Network
  • Which cables should I install, considering future-proofing? Cat 6 or Cat 7?
  • How does it work with the cables? They are bought, for example, on a 100 or 200 meter (328 or 656 feet) roll. Do connectors need to be attached afterward?
  • How are the cables connected to flush-mounted sockets?
  • The central point should be the basement. Everything should come together here. Do you use a patch panel (which I have never heard of before) or a router with switches? Internet will be provided by a cable provider. Would the installation then be as follows? Wall socket in the basement --> cable provider’s modem --> router --> patch panel --> flush-mounted sockets?
  • How are the network cables actually routed? One cable from the patch panel to each flush-mounted socket? The sockets should each have 2 ports. Or do you have to run 2 cables per socket? IMPORTANT: At least gigabit is required everywhere, preferably 10 Gb! If you assume one cable per port, that will result in a lot of cables.
Home Bus System
  • Our house should also be future-proof. I keep reading about KNX/EIB bus systems for homes. Can you recommend them? I am thinking, for example, of programming lights and monitoring and controlling the heating and ventilation system.
  • What do you think of the company GIRA (KNX system, sockets, etc.)?
  • For security reasons, I do not want the home bus system to be connected to the Internet. I do not need to control the heating via the Internet, etc. Is something like this possible (a private home network)?
TV Wiring
  • TV wiring is actually related to my questions about network installation. What kind of cables are used here?
  • Is one cable installed per socket?
  • How is this implemented if you have a satellite dish with one LNB? Can the signal be distributed throughout the house? Can everyone watch what they want? Or is additional equipment needed?
Sorry for the many questions, but I need to close my knowledge gaps step by step.

Thank you very much for your help.

Hi @Steffen80, we are also having fiber optic installed in our new build, but I want to use CAT7 cables to network the house.
I believe CAT7 supports 100Gb.
According to the telecom company, the fiber optic connection is 100 Mbit.

So CAT7 should be more than enough, or am I mixing things up?
And how much did you pay for your fiber optic cables? I thought they were much more expensive than CAT7 cables.

Mycraft, are you of Polish or Italian descent? At least when I look at the Hotbird satellite, it doesn’t make sense to me otherwise, unless you understand one of those two languages

Neither, but since I’m not completely clueless linguistically, I can at least read and understand both languages...

But back to the topic, Astra 19.2 and Hotbird are the usual combination that can be received here without much effort. Astra 2 is more for the US and UK.

I have 16 cables from the 4 LNBs to the multiswitch, and from there 8 cables to the satellite outlets in the rooms.

The multiswitch then distributes all signals to the correct receiver at the right time.

You just need to aim the dish at any one satellite... the others are found just to the left and right... they’re all above the horizon anyway...

Cat7 is, I think, 100Gb.
Fiber optic according to the telecom provider is 100 Mbit.

You are mixing everything up.

You are talking about the internet connection TO the house. Cat7 is copper cable, and it has its limits (where exactly, I don’t know... but 100 Gb is doubtful). Fiber optic is fiber optic and is currently almost unlimited... it should easily handle a petabyte.

I am talking about the wiring INSIDE the house, not to the house. Consider yourself lucky if you get FTTH (fiber to the home)... I am getting it too. With an additional payment of 31,000 EUR. Welcome to Germany (third world when it comes to internet). We are building in a NEW BUILD area, and the idiots from the telecom company installed copper cables instead of fiber... well... now they can charge me a fortune!

In our new development area, fiber optic cables are being installed directly to the house right from the start.

How much did the fiber optic cable cost that you installed inside your house yourself?

@Steffen80 what kind of interfaces are you using for fiber optic?
In the end, even you fail to achieve 1 gigabit with Cat6 and 10 gigabit with Cat7 on most interfaces. As mentioned elsewhere, most TVs nowadays only support 100 Mbit.

None so far. I simply installed InLine fiber optic duplex cables. The cost per meter should be around 1 EUR.
