It's crazy to me to think that I was hoping to move my home network to 10GbE in the next few years, around 2006-2007... Twenty years after most home networking is still at the 2005 level of a 30€Netgear GS108
10Gb/s Ethernet: switching to a Broadcom SFP+ module

Re: 10Gb/s Ethernet: switching to a Broadcom SFP+ module
#82I feel like we have moved into the era now where if you were putting cabling in the walls for networking you should be choosing fibre now. Not necessarily because we are definitely at the stage where the home needs it, but because the off ramp is clearly happening for ethernet at 10gbit/s and its really high consumption and heat. Switching to fibre after 2.5gbit/s seems like the thing to do now and plenty of us now h…
I don’t think we’ll ever see fiber ports in consumer devices. If we ever get beyond 10g connections in consumer devices, we’ll figure out how to run it over cat5e. I’ve got 10g running just fine over an 80 foot run of 20 year old cat5e that goes from my bedroom, up to the attic, across the house, down three floors to the basement, and across the house in the other direction. I bet you could get 25G over cat5e at these distances using FEC and some superhero-level codings that’ll be feasible by the time we need it.

#84Recommendations for 25Gbit next please!
Definitely DAC or fiber. There is a 25GBASE-T standard, but no actual products exist.

What for? Ethernet is what you ultimately need, because that is what devices such as PCs and WiFi access points use. I experimented with SFP for a while, but ultimately concluded that it isn't worth the effort to add SFP cards to PCs now that that low-power 10G Ethernet chips like the RTL8127 are available. High-end motherboards already have 10G Ethernet and soon lower-end models will too. 2.5G is practically standar…
> What for?

If you're putting stuff in the walls, then you should try to target something that will be adequate both today, and in 10 years from now. Increasingly…
> And yes, before you ask, there is a 25gbase-t standard. Maximum distance: 30m (100ft). 100ft from panel to panel in a house? Oof
Not to mention termination and interference considerations, etc. When I looked at it, I decided anything over 2.5g just wasnt worth all the extra hassle vs running fiber instead.

Yes, but 10G really is the limit. I'll eat my boiled boots if 25GbE copper becomes anything you could remotely consider "common".
We are pushing multiple gigabits over 100 year old phone lines so never say never.
Re: 10Gb/s Ethernet: switching to a Broadcom SFP+ module
#87Some time ago I was playing around with 10GbE using a Macbook Pro. At the time that meant a Thunderbolt adapter (and still does). Thing is, the one I got was essentially just a giant heatsink [1]. It was a beast and belied just how much of a problem heat distribution was. I'm not an EE so I'm not really sure why, other than by looking at what high bandwidth cables have done since. 10baseT (!0Mbps) came out in 1990 (t…
We never really got mass market 10GbE. The controllers were too expensive. The cable requirements were quite high. And heat was an issue.

What? Ethernet is a layer 2 protocol, SFP and RJ45 are both layer 1 (PHY). Ethernet runs fine over both SFP and RJ45.

There are probably still a lot of cases where you would want PoE though right? Cameras, WAPs, etc.
Waps are next to power, some even have SFP+ ports
But why...it doesn't solve a problem we currently face. We aren't even anywhere near 10Gbps in RF. And that's assuming you are maxing all three bands.

I did just that relatively recently in a house we bought. OS2 single mode duplex throughout the house, all converging to a trunk which is available in three locations for equipment. It's basically future proof, but also has its own well, things. You can't really plug into a duplex (I wish though), you have to put a small switch to it with SFP+ or 28 or whatever the speed you want. Higher speed switches are also a tad…
So tell me... how much did you spend? Is fiber doable without insane money.
Fiber optic cable itself isn't that expensive. You can easily get it for less than $0.20/foot.
It shouldn't be that much different in price to run fiber verse running cat6. The expensive part is the labor, not the cable.
