The Future of Home Networking: SFP+ vs. Ethernet
Вставка
- Опубліковано 1 жов 2024
- As technology advances, so does the way we connect to the internet and other devices. In this video, we look at the two leading technologies for home networking - SFP+ and Ethernet - and discuss the pros and cons of each. We'll also explore why SFP+ is becoming more popular in home networking
and look at the cost considerations.

Power consumption should be included in the list of considerations. A 10GbE port draws 8-10W _continuously_ - even when there is no traffic. This is about 10x that of SFP+. The 802.11az standard will address this but widespread availability seems to be quite distant. Depending on local electricity prices, the operating costs (including cooling) of a 10GbE home network could be enough to tip the balance in favour of SFP+.
should wire your house up in fiber, cuz you won't have to replace it. just switch out the hardware as tech changes
Fiber is the best choice if you can run in the walls, and terminate it to a wall socket, or similar. But from the wall (to a switch) then to devices is where you need to bring out the ethernet.
Agreed that Fiber is the best long term choice, if you want an easier and cheaper setup ethernet might be the way to go, especially for People renting. I think 10gb will also last the home user for a good while.
@BuzStringer, currently, my fiber comes out of the wall and goes straight to switches. I need to add the LC sockets... but since they don't exist, I need to design something to accomodate LC couplers and 3D print them. I've used 50m OM3 cables, even when I only needed 12m. After STRUGGLING, literally sweating buckets, and getting glass fiber in every orifice, I've managed to get the cables through... although I still need to repair all my drywall/ceiling, and the cables came out pretty mangled but still work.
@@raydioz They do exist, though. You can buy LC keystone jacks and put them into any standard keystone wall plate. Which is exactly what I did when I wanted to run fiber between two rooms: put an LC keystone jack in the wall plate in each room and run a short OM3 cable (needed short boot ones) between them. Total process took me maybe five minutes, though I was just going between an existing cable run. Not sure why you needed to use 50 meter cables for 12 meter runs either, OM3 cables are available in any length you could want them.
A counter argument would be that fiberoptics is still very uncommon.. I can easily picture an electrician tugging at one because it's in the way and by this single action destroy your network. I'd always go redundant - fiber and ethernet in the wall happily following the same path. If the fiber gets snapped you're not stranded
SSDs and their speed pretty much blasted the door wide open for faster home networking. Where a fast home network used to be a waste of money aside from the richest lf homelabbers among us, it now is a necessity for most tinkerers as the bottlenecking is quite severe (gigabit doesn't mean 1000 mo/s after all... So far from it). Why spend all that money and time on a NAS when gigabit network speeds mean that it wont be all that practical to use? Why build a NAS in the first place when users are going to overload the network as soon as they start streaming something heavy from the NAS? Gigabit is meh, 2.5G is "reasonable" for most users, 10G for the enthusiast and 25G for the enthusiast with deep pockets.
We need someone to come along and create a new protocol.. it was never meant to be pushed this hard in a consummer's environment.
I picked up a couple of 6 port 2.5G switches for like $35 each. They each have 2 10G capable SFP ports.
I figure I can use the 10G lines as a backhaul and then have all the clients on 2.5G, that's plenty for now.
SFP vs ethernet isn't a thing, because ethernet can be run ON SFPs (as is stated in the video). What this video should be really is ethernet vs fiber.
It's still Ethernet if you use fiber. Should be called CAT vs fiber or copper vs fiber
@@janludwig7286That was a typo on my part.
Agree, I was confused by the title since sfp IS the transceiver for both copper wire and optic fibre. 😅
I find this video very, very help full , I was looking for good sfp+ transceivers for tl-sx3008f 8port sfp+ switch
Glad it helped
The highest speed of an absolutely modern, perfect NVMe M.2 device is 242 gigabit, though you'd probably be closer to 50 gigabit with commercially readily available (and affordable) devices. Or about the speed of a current, top-of-the-line SFP+ device.
And, since you can send SCSI over a network, you can just use a network server ... as a hard drive ... without sacrificing performance.
And that's without mentioning QSFP.
You make it sound like a remote bootable drive is a new thing that hasn't been around since mainframes were the main way people consumed computing resources.
When many of current motherboards come with a 2.5GBase-T ethernet port or more, keeping other network gears like switch and router with only 1gb capability is imho wasting. And these days local file transfer in 1gb LAN network feels very very slow. If you have NAS with 1gb ports, you may not want to utilise it much any more at least for video editing. I am going to upgrade my local network within a month period. The gears are now inexpensive if you know where to look.
Are there ways to convert an RJ45 socket to SFP+ fiber?
You can add SFP+ network card to your computer.
For connecting a 10 gig SFP+ transceiver to a 10 gig RJ45 port, you'd need a media converter, which go for $60-120 USD. For connecting an 10 gig RJ45 cable to a 10 gig SFP+ port, you'd need an RJ45 SFP+ module, which cost around $40 for short-range (30 meter) modules, but be warned that they run very hot, hot enough to burn you if you touch them. Of course doing all this with regular SFP (1 gig) is a bunch cheaper.
It's much cheaper/simpler/easier to just add an SFP+ network card to your computer as Sasoon2006 mentioned.
2.5 GB Ethernet will prevail for home use.
It will be cheaper.
Most Ethernet cables can still be used.
Only SPF is required, not SFP+ 10GB.
Everyone knows about it.
And it's enough for a 1GB glass fiber internet connection.
1 gig home internet would be a bottleneck in many places. Multi-gig home internet connections are pretty widespread now. 2.5 gigs is probably enough for most people, though it'd bottleneck you on the highest speed tiers, like Bell Canada's symmetrical 3 gig service.
RJ45 at 40Gbps is already extremely cheaply available (cat8 cable).
Copper will stay the main choice for the majority of home applications.
The cabling? Sure, yes, but that's the easy part. The transceivers are where the trouble lies. You can go out today and buy a 40 gigabit network card and a QSFP+ module for around $90 USD combined brand new, but you can't even buy a 25 gig RJ45 network card. You can buy a 10 gig RJ45 network card, but their cost only very recently dropped below that same $90 USD mark. 10 gig RJ45 ports in switches still have a big price premium over SFP+ ports, even when you take the the cost of the SFP+ module into account.
I suspect that where we'll end up is the same place we're at today: enterprise and enthusiast home users will adopt fiber ethernet standards, and eventually, years later, non-enthusiast consumers will get similar speeds over copper when the costs drop far enough.
