Hi guys, I am building new house and in next days cables and data cables will be installed. Which cable for good speed in future should I use? CAT6 or CAT7? Dont you know if I use CAT7 cables, is possible to use it with standard CAT6 connectors of todays devices? THANK YOU!

If you have the ££ then go for the best for future network bandwidth.

What do you mean "future". This is the same silly thing people did to put in cat6 rather than cat5e. Guess what the market went from 1g which runs fine on 5e directly to 10g which requires cat6a or cat7. All those people who thought they would "save" money in the future found out they wasted it. The now run 1g over their very expensive (at install time) cat6 cable and if they ever want to go faster will have to replace it just as if they had put in cat5e.

The question is do you really think that home machines will be able to actually use 10g even in the next 10yrs. If you look at what most people have even 1g is very much more than they can possibly use. You have to come up with very specialized conditions to even need more than 100m. Your average person likely uses less than 10m since all they to do is surf the internet.

So you need to be very good at predicting the future, by the time affordable 10g interface reach the consumer market and applications actually need to transfer that what other technology might exist that makes the current 10g methodology obsolete.

By "future" I mean quality 10Gbit connection between home servers. I dont want to have in my ultra modern multimedia house 1Gbps till my end of life.

Go for it then its your money. Just remember most people do not stay in the same house for more than 7 years.

You can never really predict technology who knows if ethernet will even be the optimum technology by then. It is highly likely something else will be used because of the limitations to throughput in ethernet. This is already seen in storage networks..and this really is the only area that comes close to needing huge data throughput.

7 years, hmm 4 houses in 42 years of life ?
Yes Cat6 more expensive, but better shielding, probably last longer and who knows what bandwidth we will have in 10 years.

I recently debated this whole thing and looked at this way. Your network can be 10gbps all you want, but even top of the line ssd raid setups will only be able to read/write at about half that speed.

Cat 5e is pretty much capable of cat6 speeds, cat 6a is capable of 10g, and is considerably cheaper then anything past that.

I went with cat 6a on my network with standard gigabit switches and interfaces. for a few reasons, mainly cost and availability. I can achieve 1gbps between a few of my machines, but the majority of my devices either run at 10/100 or have mechanical hard drives that cant even come close to fully utilizing the speed.

Unless you plan on updating every device in your house to the latest and greatest the moment it is available, you will not see even the full potential of 1gbps Ethernet for a long long time. I recommend you save yourself some time and a lot of money and go with the Cat6

With current SSD drives pushing past 500Mbytes which is around a 50% improvement in about a year and a half, 4k tv's needing around 10gbs because you never get max bandwidth, going to be throwing stuff about your house I would lean towards cat 7a if there is only a few hundred pounds diffrence. I can always use sub spec (ie cheaper cat) heads and easly change them later if I need to save cash.

If I can not afford cat 7a, then yes cat 5e would be my other choice. Only if I had issues with interference would I look to maybe use some better shielded cable, or some out door cable if I'm running it down to the bottom of my garden.

I an a big fan of high end structured cabling especially with the issues you can suffer from wi-fi networks when there is high density. I can quite happly upgrade my wi-fi routers from n to ac with 1gbs backplanes to my gig switch where my nas' s sit. Of course if I had 7a installed, I can keep upgrading my switchs and routers with the newest affordable tech upto 40gbs per cable before I need to get inventive.

If you have a large property you can of course just put in some strategic 7a and do the rest in 5e, although the cost per point will not be as good as having everything done in one cable type.

You sound like one of those people from the 1990s that thought 1GB of RAM was only going to be necessary in the year 2100.
