Hello, new findings about that SFP problem !! Today finally some lucky situation haappened and my friend borowed me new L009UiGS-2HaxD-IN. And guess what happened, SFP on RB5009 stoped flapping and finally get stable data transfer. So finally i have at least some chance to resolve it by new router o...

Yes, 10G and 1 G DAC are confirmed that works. But i need connection for 180 meters.
Unfortunately DAC out of range here.

Hello, there is still no solution for the RB5009 <> RB962UiGS-5HacT2HnT 1g SFP connection even on the version 7.11.2 SFP flaping 2 times per second on the RB5009. Do someone have RB5009 some type of 1G SFP working ? Or does mikrotik team focus only to solve 10G request for the RB5009 and 1G is still...

It is 245 days after my workaround opti convertor installation while waiting to mikrotik resolve issue on the 1G sfp Still same problem and even original mikrotik sfp is not abble to comunicate and flaping in the RB5009.

New update: RB962UiGS-5HacT2HnT ROS 7.8 + same firmware RB5009UPr+S+ ROS 7.9 + firmware upgraded *) sfp - added log warning about failed auto-initialization on RB4011, RB5009 , CCR2004-1G-12S+2XS, CCR2004-16G-2S+, CCR2116-12G-4S+, CCR2216-1G-12XS-2XQ devices; *) sfp - allow modules that hold "T...

Update regarding to: ROS Release 7.8 *) sfp - fixed false link detection with S+RJ10 on RB5009; *) sfp - fixed reading of SFP EEPROM on single SFP port devices; *) sfp - improved optical modules SFP compatibility on CCR2004-16G-2S+, CCR2004-1G-12S+2XS, CCR2116-12G-4S+ devices; Tried all types of SFP...

Tried setting static speed/duplex and disable auto-nego?

Yes, not even going up without this setup. But RB5009 flapping cca 3 times per second

Hello, does anyone receive response from mikrotik ? I found that in 7.8beta2 *) sfp - fixed false link detection with S+RJ10 on RB5009; Release 7.7rc5 *) sfp - added 2.5G SFP module support for RB5009; But something like S-31DLC20D 1G single mode still not working :( it really bothers me, that it´s ...

Similar problem here with FS.com modules (which work fine in a HexS) - for now the R5009 is just a very expensive paper-weight.... If that problem would be just about the exotic type of SFPs like cisco I say nothing, but as this is the same even I bought MikroTik, that really annoying me. Even wors...

Hello, update on the case: I bought mikrotik sfps S-31DLC20D no any change, still port flaping on RB5009. I have a suspicion that devices really don´t like each other :shock: :lol: As I tried that TPLINK media converter. ETH1 RB5009 - media converter >>> fiber >>>> SFP1 RB962 - works no mather on sf...

Update: MaxLink ML-S31D-3 revision A just arrived. Manufacturing date: 21-11-22 so brand new SFPs and the same behavior. RB5009 flaps, RRB962UiGS no problem. https://i.ibb.co/nMLM3YC/SFPPICTURE.jpg Test with the same SFP and Media convertor TPLINK MC220L <> towards RRB962UiGS , link was up and worki...

Hi,
I am facing the same problem, did you resolve it ?

Or do you have any statement from Mikrotik support ?

Hello, I have SM optics line 138 m between RB5009UPr+S+ and RRB962UiGS-5HacT2HnT both ROS 7.6 / firmware upgraded. Both sides have manual ethernet 1 Gbit speed, a full duplex. I tried 2 x SFP CISCO GLC-LH-SMD which have these parameters on the line: RB5009 TX -7.135 dBm RX -7.309 dBm RRB962 TX -6.83...
