Wondering if anyone has tried this.

I had issues with ubiquity's transceivers. Meaning they would not work in 10G.
I wound up buying a full duplex auto negotiating transceiver from amazon. not I can get over 1G download speeds.
My PC has a 5GB ethernet port, so I got to thinking, and looking at 2.5 switches. (my modem only has 2.5G port or 1G ports on it)

So port 11 on the DMP looks to be an output port according to this. Which is the port under the 10G SPF port.

So main question is even without buying a 2.5G switch, would that #11 SPF port, OUTPUT with a auto negotiating SPF transceiver to the PC?

@ch33zw1z and or @aigomorla since I am almost certain you both have experience with the DMP or SE.

I am going to try it. Will lyk.

Port 11 with negotiate speeds to the other end, sure. Will it negotiate to speeds other than 1 or 10 gig, unlikely

What are you trying to setup a 10gig link between that didn’t work?

I was able to get a 2.5G link from modem to DMP with a negotiable SPF. Ubiquity's SPF to rj45 are 1G or 10G only.

If the incoming SPF I ordered which is same as one I'm using to get over 1G now will link to my PC at 2.5 or 5G then I will look at a higher rated switch.

Currently limited by my modem provisioning. Which is 1.2G and 60 upload. But our current system as is (HFC) has capacity for 2G and 175M upload.

I just kinda caught last night that port 11 may be an output SPF connection that is possibly for greater than 1G switching.
If the DMP CPU can handle the overhead of connecting it to a 2.5 or 10g switch. (If that makes sense)

I should be able to confirm tomorrow night if shipping isn't delayed.

EDIT: Forgot to hit enter on this post. So I will add to it below.

Yes it does work. Current modem provisioning is holding back but our rural system can get to 2.1G and 175M up in current state.

11 port with transceiver auto negotiated to 5G link speed of motherboard.
Port 10 SPF connects to modem which only has 2.5G port on it.

10Gig, or 1Gig, supported speeds. 2.5 isn't listed. Anything else is YMMV.

I am being limited by my modem provisioning, which is 1.2g d and 60M up. It only does that initial burst up sometimes past 100 but always settles at 60-65m ul.

This does confirm though, that I can go, 2.5G or 10G switch on the UA6 and 7, I believe the cameras are 1G, but my PC is really MY main point of concern. I do have a MOCA device with a 2.5G link but 100M worked fine also.


Here is the SPF to RJ45 I have, 1st one has been flawless since we last talked about DMP.

Ok, were all limited on the WAN side, that's not really what you're talking about though.

Whatever speeds you get you get. The UDM specs are the UDM specs. May the odds be ever in your favor :>

It will apparently auto negotiate if you have an auto negotiating SPF transceiver.

Which seems to be the case because the 10 gig I bought from ubiquiti and the one gig I bought from you big witty both had issues.

If u mean the cable from UI won’t negotiate other than 10Gig or 1Gig, then yea makes sense. Which cable PN?

Its the UI SPF to rj45 transceivers. Not a cable. Speaking of those I have a faulty termination in one, it's all got stuff under and against it to it's green light on the switch. I am using premade CAT6 for modem to DMP and DMP to my PC which was on the prior, it is also a CAT6 premade just shorter than 6 ft.

UI SPF to RJ45 would not do this. The right side of diagram. They are only 10 or 1.

EDIT: I didn't know that when I bought them. Thought everything auto negotiated then.

The SFP+ to Rj45 claims 10 / 5 / 2.5 / 1

SFP to RJ45 is just 1Gb

Well they didn't used to have them. UF=RJ45-10G

Must have been 2 or 4 year older ones. I was talking with you then,

sorry i came late to this..
No.. the SFP+ does not auto negotiate like a 10G RJ45 would.
Its either full boat 10G or 1G. thats it.... while as the a real 10g port would do 10/100/1G/5g/10g.

If you want 2.5gbe adoption which i did reciently.. you need to do this...

This guy needs to sit on top of your unifi system for the cheapest solution.

Then connect that guy to the unifi SFP+ port. That way the 2.5G switch talks to the unifi switch at 10G.
And then the 2.5G ports handle the 2.5G.

If your also wondering how fast 2.5g transfers are...

Its not bad... but im still keeping my main NAS's and servers tied on the 10G.

That is so weird... because every time i tried that it would default to 1G. The connection also would not be stable.
Honestly I would just sit a cheap 2.5gb switch on top which has a SFP+ port, like the one i linked...

Not too worried about everyone else's stuff. Just my PC, it has a 5G ethernet, and it says it's linked at 5g to DMP port 11 spf. Modem is 2.5G linked to DMP port 10 at 2.5G
So my PC will pull almost 1.2G down, limited by modem provisioning of 1.2G and 60M up.
My signal meter is provisioned for 2.4G down and 1.4G up and I can hit the 2G down, but our OFDMA is limited to about 175M upload due to 40/42mHz diplexers in the actives in the system. Meter can sustain about 125M up. depending on conditions since my port I am on is a 4 node port.
I swear I seen another employees modem provisioned for 144 upload. but still only the 1.2G down. Trying to figure how to get my modem upload reprovisioned higher. Corpo BS. They do offer a 100 upload in some areas. and 1G symmetrical in probably quad cities area.

But the Ubiquity SPFs I bought, early on, do not auto negotiate they are either 1G or 10G. Got some off amazon that will auto from 100-10G
I know I would need a 2.5 switch to increase the LAN, I was mainly talking of the WAN due to being hardwired to the DMP with new PC.

Just so anyone wondering in the future doesn't need to read between the lines, OP was using an older version of Ubiquiti's SFP+ to RJ45 transceiver that they no longer sell. The only options they sell now are only to GigE or can do 1/2/5/10GigE. There's some cheaper transceivers that work for multi-gig, but in my experience, they run much hotter than the UI versions (I'm running two -- one for WAN ingress and one from my Pro Max 16 PoE switch to my Flex 10G GbE switch.
