Good morning everyone,

A number of users owning an RB5009 are unable to connect to delta fiber networks using their existing sfp adapter (adapter and config are running fine with a HexS) so we are wondering whether the RB5009 would only work with sfp+ adapter? Is there anyone who can shed a light on this?

Did you tried to set the link speed manually?

Yes - no success unfortunately..

My RB5009UPr (should be identical in terms of SFP+ Port) is working fine wit a regular 10Gtek SFP RJ45 Module. However, as jookraw suggested, Auto negotiation did not work, had to set it to 1Gb/s manually.

Hello,

First make sure you are running / upgrade to latest RouterOS on the RB5009.

Do you mean "Delta Networks": French ISP hardware, Freebox Delta?
It is well-known that the Fiber cable in the SFP+ on theFreebox Delta side is too hot and is underpowered.
When the SFP+ fiber module gets too hot, it disconnect to cool down.

I own a Freebox Delta and SFP+ port on the Freebox Delta side does work very well.
You should use a 10Gtek Direct Attach Cable (DAC) and not a Fiber cable.
A direct attach cable consumes less that 1W and will stay cool.


Kind regards,
Kellogs

No, i am talking about the Dutch Delta Fiber network company - which owns Caiway. They also offer a 8GB fiber connection which will probably move up to 25Gbps on the long term - but for now i'm aimaing at 1Gbps

Anyway - i am using a generic FS.com adapter (this one: https://www.fs.com/de-en/products/75339.html - Generic Compatible 1000BASE-BX BiDi SFP 1310nm-TX/1550nm-RX 10km DOM Simplex LC SMF Transceiver Module - ) which works fine in a Mikrotik HexS - but simply refuses to work in the RB5009.

As for 10GB adapters - i have not found one yet with the correct wavelength yet (FS.com).

I'm tempted to open up the Delta router and retrieve the provided fsp and put this one into the RB5009 to see what happens...

Addition: there are at least three other users suffering from the same problem - and one these has successfully established a connection with another piece of his own hardware - effectively ruling out the possibility of a faulty RB5009 - the problem seems to located in the hardware compatiblity between (generic) sfp's and the RB5009.

I'm pretty sure this will be solved in the near future, but for now the RB5009 is being used as a very expensive paperweight....

I have a working generic 1G SFP module from fs.com (SFP1G-SX-85) in the RB5009 ROS 7.7rc2
The peer is a mikrotik CRS112 with the same sfp multimode module.

But it seems to be not 100% reliable.
During my tests with unplugging/plugging sometimes I needed to disable/enable the interface of the RB5009 to get it working again.

Thanks - i will try that one. I was considering a 10G sfp+ module but that is not available as a BiDi with the required wavelenghts. I also got confirmation that my existing 1G sfp is also EEE compliant so it all seems to point back to the RB5009 not accepting the my sfp. I will compare it to yours today and also load RouterOs 7.7rc2 today to see if that makes any difference.

so we are wondering whether the RB5009 would only work with sfp+ adapter?

@prmfeddema I only wanted to point out that the RB5009 will work with a sfp adapter (1G) ; no sfp+ adapter (10G) needed.
My test scenario was 2 identical 850nm 1G multimode adapters; you probably need 1310nm singlemode.

What I do not understand:
In your screenshot it says "running".
Rx Power says -9.759 dBm, so it seems to receive a signal from the other end.
Why do you think that the RB5009 does not accept your sfp module?

Just noticed your reponse - yes it's quite puzzling.. the DB values show something, but there is no data coming through (it seems to be sending though)...
Up to further investigation...

Hello prmfeddema,

Did you ever manage to solve this problem. I just got my rb5009 and i am facing almost the exact same problem. I have a SFP-GE-BX40 from fs.com and my isp is also Delta. I am seeing RX power on the sfp but there are no RX packets coming in. I have also tried the sfp module that Delta suplied me with (GENEXIS 99618002) but that one also shows the same problems.

I have the same problem on mine, and I have just gotten intel 10gb sfp+ but the idea that it is heat has made me get a platform fan to place underneath it.
But I have tried like 3 or 4 models of SFP+ and finally picking supported ones.

More to follow after I get the fan.

Hello Gnits,

I don't think it is the heat in my case. In the interface it shows the temperature of the sfp around 30 celcius while it shuts down at 95. Maybe it is worth checking this for you too.

No, it's not. The RB5009 is quite picky with SFP(+) modules. Many do not work, but do work on RB4011 (which also required many ROS upgrades to solve SFP problem back when it was new).
The most annoying thing is everything looks fine for not working SFPs: It is present and shows RX power, but here is no RX data moved.

MT should work with Marvell to finally get the 88E6393 SerDes config right. Or ask the guys who ported Openwrt to RB5009. Because they managed to get all of my SFPs working in the exact same RB5009 box.

Hi Luca - no the problem still persists - no solution yet (very very frustrating). In the meantime i am using the RB5009 as a paperweight and fiddling with my HexS and the hap AX3 - only to find out that the Capsman menu entry has disappeared on my HexS running ROS 7.7 ....

that's a pitty. I guess i will just order an media converter and use that untill the problem seems to be fixed.

This was indeed the case. I bought a cheap Media converter ( The TP-Link MC220L for anyone interested) and after plugging everything in everything worked as i expected. Thank you for everyone who shared their thoughts and ideas. Now lets hope the update that fixes this issue comes soon.

I just bought two Intel 10gb sfp+ modules using the part number right off of the supported list and they still flap.

I think you can rightfully conclude that this is unacceptable. Maybe we should return the RB5009's we bought so far.

I'll go the same route for now. Thanks for the tip.

Just waiting on a ticket response. Given and rif and everything.

maybe its not possible for RB5009 to work with sfp+ adapter....
because i searched a lot but didn't find anything helpful...
[/quote]

The RB5009 has an SFP+ port so therefore it should be able to work with SFP+ modules. The problem we are experiencing in this topic seems to have to do with ROS not working with some SFP( + and non +) modules. This will probably be fixed in an release down the line but for now it seems it is a bit of an gamble to get an SFP module working with the RB5009.

Guess the cheapest way forward is to adapt LuckyLuca solution - get a tp-link media adapter and have that one handle the spf adapter compatibilities. I am going the down the same route for now - Ordered my tp-link adapter from Amazon.de for around 21 euro's (incl shipping). I will use the media adapter for something else in the future (paired with the HexS, an addition sfp adapter that i wrongly ordered. Just need to buy some additional fiber & corresponding sfp adapter).

Hi - Can i ask for you part of the config where you connect the tp-media adapter? It will save some time (and potentially pissed off family because internet is not working for 10 mins... guess you know the drill). Or is just as easy as substituing the spf-plus port name for Ether8 (or similar) in the interface/bridge setup?

Update: no need for that anymore as i have up and running

Thanks in advance

For me it was just plug n play. I assigned the ether1 port that I connected to the tplink to wan in interface list. Then created a vlan with vlan Id 100 on ether1 for internet from Delta. Then requested dhcp on the vlan and it worked.

While MT indicated that they implementated some fixes in 7.8rc3 it still does not seem to work with my setup. Still sticking to the TP-Link media converter for now.

Same for me. Sadly still waiting on a working fix.

Hi,

Same issue here. Working fine now with the tp-link ML220 but this is not what i actually wanted when i bought the rb5009.

Hi,

I'm experiencing a similar issue with my CCR1009-7g-1c-1s+pc and a 1Gb SFP. There's an active link on the dedicated SFP+ port, but no traffic passes the interface (hard configured speed of 1Gb). When the transceiver is used on the combo port (SFP / eth0) a connection is build up with my ISP.

In my opinion the SFP module should work on the SFP+ port.

SFP: 1000BASE-BX BiDi SFP 1310nm-TX/1550nm-RX 20km DOM Simplex LC/SC SMF Transceiver Module

RB5009 connecting RB960 with single mode fiber , using S-3553LC20D

I have setup on rb5009
I have stup on rb960
On the rb5009 interface it's blinking when I open the sfp interface, link on, no link, link on, no link....

On the rb960 interface it's all ok, with link on...

however, nothing pass trough this interfaces!

I have the 2 Rb's updated with 7.14.3

Please help!!!

Hello folks,
I'm having the same problems as you all.
I am struggling to connect a RB5009 to my ftth via sfp+.

Two GBic modules, SFP-GE-BX, work fine with a HEXs and a RB4011.

I have tried several configurations and....when you (unbelievably) set the auto-negotiation to on, the PPPoE client is connected.
To check whether this configuration is performant, I rebooted the router.
The same error, the message: Peer is not responding appears.

I switch auto-negotiation off and on again and the connection is established.

The result is not nearly good enough.
As long as the SPF+ port is flapping, the RB4011 remains in first place, what a pity.

I will take these problems to the German Mikrotik forum and post the thread here.
Maybe someone there will have an idea.
See you soon.


Marco

...so...I have forwarded the question in the German Mikrotik forum.
There I was given the tip (quote) to only set the possible speed and duplex modes on the SFP+ interface that the module can physically support! Such an unclean setup can trigger such behavior. So either without autoneg and statically a fixed speed/duplex value.
After I have then set everything to 1G baseT full, the FTTH connection is performant.
Unfortunately, I can't contribute any more to the problem,
I hope it has helped.

I have an RB5009 working fine with an Ipolex SFP-10G-T (SFP+ to RJ45).

No flapping, auto-negotiated with zero issues. It's been up for 30 days now since I installed it. I have to use my ISPs ONT, so I haven't tested a fiber SFP module.

Just a point of reference to it working with a module. Granted, it's RJ45.

I have an RB5009 working fine with an Ipolex SFP-10G-T (SFP+ to RJ45).

Just out of curiosity, but how hot is this SFP running when you fully utilize it ?

Looks like a toasty 59~61C.

Shutdown temp is 95C.
