What kind of cat 6 do I need?
Posted by: bazookaman
Date: November 06, 2018 08:49PM
Since they are basically going to tear off the top of my house to rebuild after the tree was removed< I figured I'd take this opportunity to run some ethernet down through my walls. The biggest advantage is that I'll have access to the ridge plate that will let me go from one side of the attic to the other. Something that was impossible before.

Anyway, I figured I'll need a couple hundred feet and I may as well run at least two lines to each drop since I'm going through the trouble. I'll probably run some to the corners of the house for some future security cameras. So I know I'm going to use Cat 6. Is there a particular brand or kind I need? Or just get the cheapest box of 500 feet? I guess Ideally, I'd get three boxes of 500 feet. So i could have three different colors. Just for my own OCD.

Unless it is going to be run in conduit or completely enclosed and protected from fire, get plenum rated cable. The jacket will be made of material that will not release large amounts of toxic gases if it burns.

I would say get the best CAT6 cable you can find. jdc will say meh, it's all WiFi anyway.

Plenum rated and get a good brand. I bought the cheap stuff once and regretted it. Doesn’t pull nice and the wires are thin and not flexible.

Also, no point in different color cable, you never see it. Could do different color jacks if you wanted but I don’t see the point in a house. In business if you have separate voice and data lines you use different colors. Or if you have runs that go from one location to another for a projector or something make those different colored jacks.

I've had good luck with [www.firefold.com] for Cat6 and keystone jacks/wall plates. I think they're somewhat in your neck of the woods, perhaps. Better total pricing for me compared with monoprice, so that's the route I've gone the past couple of times I've needed it.

I know to avoid Samsung appliances. I know I prefer Macs to PCs. Denon makes a great receiver. But I'll be the first to admit I don't know much about bulk ethernet brands. Something like this?

my guess is future proof. Also the bulk of the cost is installation (either your own labor, or pay someone else), not the materials.

I agree with getting good quality cat 6 cable, but am unclear why anyone would recommend plenum rated cable for a residential install.

It's much more expensive, and it's purpose is so that not give off noxious fumes if installed in a plenum/air return system. How is that applicable to a residential install?

Cat6 can support 1Gig over longer distances than Cat5e, and also provide for up to 10G in many instances. Cat6A does the same but over even longer runs.

If you think you need 500'. Purchase 750'.
Ehhhh... just get 1000' and be done with it.

You already have thousands of feet cable in the house that is NOT plenum rated. None of your electrical, phone or cable TV wiring would be. This goes along with all the other engineered wood, foam, fabric, plastic or glue products in the house that could potentially create fumes. I wouldn't be concerned about a few hundred feet of cat 6 cable.

Plenum rated cable is required for many commercial spaces because above the ceiling or chase spaces often double as a return air for hvac or air handling. Running Cat 6 or any type of wiring within the walls or attic space of a house is not the same type of installation and does not require plenum rating. Plenum rating adds about 2-3 times more to the cost.

Always. Four or our five cats are humane society adoptions. #5 just volunteered as tribute by showing up in our front yard as a scared and sickly kitten.

OK and the actual cable answer...
Design a 'Backbone' with at least two cables to run from one side of the attic to the other. Basic Cat 6 is good enough.

It may also be time to add a 115VAC circuit if you think you need it. NOT next to the Cat 6 cable, please. Or in a grounded EMT conduit run. Ground loops are nasty things... I once experienced a 10KV ground loop on an analog signal line buried under a high voltage transmission line. Fried the heck out of a serial port.. I had to put optoisolators in the circuit.

I have a closet upstairs where I was thinking of installing a switch. So all the upstairs would be homeruns to that closet. Then I'd have one cable running downstairs to my Harry Potter closet that houses my interweb connection as well as my main networking equipment.

That should do it. I once bought a punchdown block so I could 'wire my house up right'. Eh. too much work. I ended up with a daisy chain of gigabit switches on Cat5.

I will stress the idea.. ALWAYS have a spare line run. You may never use it, but if you need it , you'll be thankful it's there.

This is not entirely correct. Per ANSI/TIA 568, supported speeds across different cable types are:

- Cat 5e, Cat 6 and Cat 6A all support 1 Gbps across the entire 100 meter max permissible channel length.
- Cat 6 supports 10 Gbps only up to 55 meters channel length.
- Cat 6A supports 10 Gbps across the entire 100 meter max permissible channel length.

Running Cat 6 or any type of wiring within the walls or attic space of a house is not the same type of installation and does not require plenum rating.

This is technically correct. The spaces above the ceiling referred to by iamrfixit is called the plenum, hence the term "plenum-rated" in reference to cable approved for installation in such a space. Whether to use plenum-rated cable for this application comes down to how much peace of mind it will provide OP to do so.

Note that it is technically non-NEC compliant to run cables inside walls unless they are in conduit.

Thanks for the clarification!

My take-away is if you ever want to go 10Gbps in your average sized home, then get Cat6. Otherwise 5e should be fine.

You mentioned security cameras... lots of them use coax, or siamese BNC

Of course, Id just go wireless =)

Power to cameras, as opposed to batteries, would be a bigger concern for me. Of course, Ive seen wireless cameras rated at 4 months on a single battery charge... so impressive.

I'm thinking POE cameras.

Not anymore - most modern surveillance cameras are IP-based, either wired or wireless. If wired, they can be powered via Power over Ethernet (PoE).

Good to know. Last time I looked PoE cameras were severely limited -- 180p, B/W, slow to start, etc, etc. Wasnt pretty.

All these new wireless cameras with the 4+ month battery life seem like the way to go now days. No cables of any type.
