TV over CAT 7 cable?

[lilman]

Is it possible to use CAT7 to distribute TV/ satellite signals etc? I've been asked to finish a rewire off (builders disappeared), and customer has CAT7 cable run throughout property - there's no co-ax/ TV outlets. Some guidance as to what is possible would be much appreciated. Also - anyone know any useful sources of info on this kind of subject?

yes,

Im not big up on it but I use 5e and wifi to stream TV from my computer, also done a few places where we installed fibre optic and cat6 for TV/video etc,

not sure how your customer is intending to do it but it is doable.

Cheers - I think he wants to use the CAT7 in place of sat/ co-ax cable for freeview as well as data/ phone etc - not necessarily just to stream TV from a PC.

What's he wanting doing???

Wire TV / BT / network all back to a patch panel??

I presume that's the idea - I won't see the property 'til tomorrow afternoon - just general discussion on phone earlier.

I would assume he will need a converter of some sort somewhere in the system, bit like trying to go from 230v AC on 2.5 T&E to bell wire, doable if you convert it somewhere.

its not just a simple splice.

NOZ is your man here, so I'll keep my nose out.........

Like buggery I am....

can't be that hard though... different patch panel/switch for eace service and hook up as required,, just use the right adaptors

but in all honesty I have not installed anything like this myself... I wouldn't mind a stab at it though!

Oh.. and from what I've gathered install 2 x catX cables to each point

totally,

I never install a data cable on its own, always in pairs.

You'll need GG45 connectors for cat7, the standard RJ45 will not fit.

Nexans are the manufacturers & I belive Edmundsons are an outlet for them.

would a normal domestic even know the difference between cat 7 and 5e .?

just a question mind,

Ive just been under the impression that everything else in mind you wouldnt ever know.

That would depend on what you're distributing internally wouldn't it??

Isn't Cat5 100Mbps? so even if you had 20Mbps broadband then your external internet connection would be the slowest part of the system..

however if you had a media server distributing HD video then I think Cat 5 would be hard pushed,,, wouldn't it???

I think the quoted figures are what the manuf are guaranteeing at the lengths,

who is going to have 100m of catXX in their house,

also, who actually has proper HD .?

but I understand where this is coming from,

over-engineering comes to mind in this somehow,

this is going to cost a fortune to achieve very little. IMO

physicaly cat7 is slightly larger csa, each conductor is single core (thats all I've seen anyway),Each pair are screened & are more twists per meter, all pairs are then screened with a twisted earth braid.

If you are going to use cat7 dont untwist all the pairs at once when terminating, the white of each pair isnt traced with a colour.

I have a job sometime this week of trying to use a 300 meter length of cat7 & we are wanting to see if PoE works at that distance to a remote node of a mesh network.

Cat 5e will do 1000Mb/s

Cat 6a will do 10Gb/s

Cat 7 will do 10Gb/s

Considering that 5e will push through 100MB/s its not really a problem of how much data you can push.

Cat 7a can be certified up to 1000MHz though which means it can be used to transmit CATV signals (at about 850MHz-ish?)

Personally I'd have just run co-ax for the TV and Cat 5e for the data as (last time I looked,) Cat 7 is mentally expencive.

But yeah it should be able to cope with the TV signals no problem at all.

Try Scneider delta 8 system - distributes data / tv / telephone all on single cable - think its compatible with cat 5 cable

Cat7 seem rather OTT for domestic, particularly if you see what can be done with HDBaseT on a single Cat5e

I've use these passive baluns http://www.madnat.com/prodtype.asp?s=nyiufx117373&strParents=136&CAT_ID=332&numRecordPosition=1 provided the runs are not too long it work surprisingly well, however coax with Cat5e/6 would have made more sense
