SFP/RG45 Adaptor

Not sure if this works, I think it will, but I'm sure those in the know will advise me otherwise

I am thinking of buying a Draytek 3912 which has a 10G SFP port

Would I be correct in thinking that I can take a CAT6 cable from the ONT and plug this into a SFP/RJ45 adaptor ?

Is there specific SFP/RJ45 adaptor that I will need ?
I have found this one here, which looks to be correct

Any help appreciated

Yes, it should be fine. Note: if teh port is 10Gbit it will be SFP+


What I don't like are the prices in your search! I use Ubiquiti and even their "expensive" equivalent is about £50-60. There are quite a few third party adapters around and I use them in my UI eqiupment to convert to Fibre. You may find someone who has successfully used a third party one on Draytek.

I also ask if you actually need 10G - what service do you have? And does the ONT support 10G too?

I'm completely confused as what you are trying to do here,

Firstly the draytek 3912 is a very expensive piece of networking equipment ...... i say that because it seems to be overpriced.

Secondly and more importantly, if you are staying on sky's fttp - at the most a 2.5gbit connection.

Thirdly why waste a 10gbe sfp+ port when theres 1gbe ports on the switch.

What is your reasoning to get this switch, because atm i can't see the need

No I don't need 10G, but that's what the router has
I am having the 1.8Gb service installed, so the ONT will only support up to 2.5Gb

I am assuming the SFP will adapt to to whatever the throughput is

I'm completely confused as what you are trying to do here

What I am attempting to do is use one of the SFP ports to free up one of the 2.5G ports

Maybe is overpriced, but there is not much to compare it with and I have always used Draytek
If you know of a comparable one, then I am open to ideas ( Fan less )

Thirdly why waste a 10gbe sfp+ port when there's 1gbe ports on the switch

Not staying on Sky, moving to a 1.8G service

The module Draytek list as being compatible with that router, and able to run at 2.5Gb, is this one

have you actually brought the draytek yet?

What features do you need ? I do understand that once you are in the Draytek club you kinda don't want to leave which is fair enough but from what you are saying the 3912 if not already brought may from the port issue alone be not suiteable.

If you have brought the said unit, and need further 2.5gbe connectivity, then a cheap 4 port 2.5gbe with a sfp+ port switch may be better and get a 10dbe sfp+ dac cable between the two switches then going the route you intend to go down with the sfp+ to rj45

Thers have questioned whether the Draytek is overkill? From what I can see £800 - is that right?

Have a look at teh UI UXG-max https://uk.store.ui.com/uk/en/pro/category/all-cloud... Under £200. It has both 2.5Gbit WAN and LAN


If you still need an SFP module - you need to ensure it will support the ONTs 2.5Gbit as some only do 1G or 10G.

No not yet purchased it yet, I have found it at a good price of £789 though
I love the build quality of Draytek routers and the interface I have got so used to, so yes I am in the club as you say
Still open to a comparable router with the same build quality/features though

I was going to put a 2.5Gb switch in the loft anyway, so its no problem at the end of the day, just thought it would be nice to have a spare 2.5Gb port available

as Mhc said, and i said in around about way, is this is overkill.🙈.

What is your current network map?

Also what services or servers are you running, as we can give suggestions with out that info, but it would help to provide with the right equipment.

From what you have said, at most is that you need switching not a router.

Something that is right for your setup and probably several hundreds of pounds cheaper!
