Hi, so to answer my question, its cat6 we are talking about not cat8. As a network engineer who has overseen some major cabling projects, I am totally aware of Cat8. Personally wrt to network services (rather than raw video material) I see no use for cat8.


Reason, .......... as you step into interface speeds greater than what cat6 can happily carry (ie 10/100/1G/2.5G/5G and 10G to around 50m) then there are better options, ie DAC in local cabinets, and fibre beyond that. In domestic or even enterprise outside of data centres, I still am not totally convinced of a need beyond cat6 in UTP cable requirements. I should also point out that 10G on copper has limitations that DAC and fibre do not, in essence latency and power consumption. The latter is getting better with new chips, but the latency cannot be resolved. And while it has minimal impact on client machine performance its impact on high access db type applications means its rarely if ever used in Server/DC applicaitons, DAC and fibre are used instead.


That said, at work we regularly use cat6a SFTP, but not for speed performance but security, again only in limited situations, more typically fibre is used to achieve both.

What @cyril7 said.

 

In most datacentres I have worked in they will always run fibre between racks and the only place copper is used these days is to wire up the servers to the top of the rack switch. And you can easily run 10GB if required on a sub 5 meter direct run.

 

For residential I am still struggling with wanting to pump HDMI around the house. Smart TVs have ethernet ports, or mount your preferred streaming device behind the TV and stream that way.

 

The only use case I could think of would be if you have an AMP you want to connect to be Streaming box -> AMP -HDMI over Ethernet-> TV. And have the Streaming box and AMP in another room. But if that is the situation I would use optical from the TV out and then an optical in TOSLINK into the AMP if it's under 5M or get TOSLINK to ethernet converter then you're good up to 150M

Reason I have HDMI around the place is to have the same thing on multiple screens. HDMI over TCP boxes seem to all be quite trash with compression and latency and frame drops/doubleups, HDMI over bare cat6 is much better but still has some problems with devices showing static when they cant sort out their edid or hdcp carryon.

 

For my output of my NVR which is only 1080p I have a HDMI to 3GSDI adapter, then a SDI splitter and a whole lot of BNC to F connector adapters and the old TV antenna coax. The only other place I need the one thing on multiple screens is handled with 7.5m HDMI cables and a repeater in the middle of it since 15m ones seem to be universally useless.

 

When I have the walls open next I will probably see about getting some fiber to put in, but realistically till terminiation become cheap and easy it will just sit unused.

I'm wiring up my house, not a datacentre.  I am quite happy to spend $100 extra to go from CAT6A to CAT7A to future proof the whole house but i certainly will not be paying to have a technician terminate fibre runs into every room. Copper is something the amateur can easily terminate themselves.

 

I'm gonna get some of the PDL319MKC and see how it goes, will report back when they come in. They seem hard to source i might have to ship from Oz where they are known as the Clipsal 40ADPKS-TN

Hi, if your in Auckland there seems plenty of stock.

 

 

By the way, probably cost you more than $100, its not so much the cable costs, but the connectors as they are shielded so the cost goes up, also be aware that using non UTP cables brings about a whole bunch of issues with regards to earthing, earth loops and if done wrong you end up in a way way worse situation than if you just went with UTP, believe me as we use cat7 (ie cat6a SFTP) at work and it can be a real bother.

The shielded CAT8 ones i got were NZ$60 delivered for 5.  And then looking at about $3 each for the iconic adapter, so about $15 per port, roughly double the PDL CAT6 one, but not too extortionate IMO.

I got some field termination plugs from them too to use for the WiFi access points in the ceiling, save having to use patch cables there.  I'm tempted just to use field termination plugs in the basement too, avoid the cost and hassle of a data cabinet.  Just have a bunch of wires coming out the wall and plugged straight into a switch.

 

Thanks for that Corys link, i'll pop to Mt Eden on the weekend.  Shame the city branch doesn't have stock (and shame you can't use their website without opening an account).

OK so the PDL319MKC works a treat.

 

Once you watch the installation video in the FAQs section and discover that you need to completely remove the retention clip, they clip in quite nicely.   This could be an issue if you want to install other mechs in a multigang plate and those other mechs require the retention clip.

 

And although everything is square, so you might think it would clip in rotated either of the four ways, it only clips in one particular way. So if you wanted the plate vertical, your lan cables would plug in vertical.

 

And it only cost NZ$6 for 10 at Corys.  Add in the US$70 for the keystones, and i'm looking at NZ$10.60 for each datapoint (plus whatever the iconic wallplates cost)

Awesome. Thanks for posting photos and confirming this. I will buy quite a few of those cable matters keystones too then.




Do whatever you want to do man.
