100M sfp will work only in devices that support 100M. Also 10Gb modules.
Yeah, I'm aware of that, but there is also something called Dual Rate SFP Slot that supports both, 100 and 1000 mbit SFPs as well as 10 Gig SFP+ Slots that support 1000mbit SFPs. I just wanna know if the RB2011 has one of those Dual Rate Slots (100 and 1000) or Gig only and I'm asking that question for very a long time now, WITHOUT A REAL ANSWER!!!!
My e-mail to the MikroTik Support more than half a year ago said it is Dual Rate. Many people in the forum asked the same question. Normally there was no answer (like at http://forum.mikrotik.com/viewtopic.php?f=3&t=49891
Question 5) or something like "if the SFP meets SFF..." Now I have some RB2011LS-INs, plug in an SFF conform 100mbit SFP and it DOES NOT WORK! A copper SFP that works with both, 100 and 1000 mbit also won't work if I set the speed to 100 (which works on capable devices) so it really seems that RB2011LS'slot is GIG ONLY!?!
Another funny fact is that the Wiki is mentioning RB SFP5602D-53 and RB SFP5602D-35 SFPs that are supposed to work on RB2011LS-IN with the range from 155 mbit to 2.63 Gig where 155 should be 100mbit Ethernet i suppose (or what else, OC3 *G*).
Are those MikroTik SFPs of that (normally) rare kind which are connected to the device with gigabit but the optical interface is just 100 mbit? I used such SFPs a few times, but I 'm sure that it would have been a much better choice if it would be a just Dual Rate Slot!!! We are all looking forward to replace existing installation or CPEs and not just new deployment. This won't be possible for existing 100mbit FTTH networks without a Dual Rate Slot...
(or only with buying new (MikroTik) SFPs and throwing away the old ones)
On almost any RB2011 topic here this has been discussed with no clear answer ever, except the time when Normis was talking about the 1,25 Gig SFPs for the first time a couple of posts ago and that's why I came up with the question (again) to finally get an answer but I still don't know if it's a software issue or the hardware slot itself why nobody's 100mbit SFPs are working (see http://forum.mikrotik.com/viewtopic.php ... =0#p316721
It's pointless to try to use everything you find in the toilet and then fill the forum about that.
Who the f*&% is talking about anything from the toilet? I just wanna know if the RB2011LS-IN has a Dual Rate Slot or not! Damn easy question but no answer ever. I don't wanna year anything about SFF or whatever, I wanna know if standard 100mbit SFPs are supported or not!!!! Many people mentioned 100mbit SFPs to Normis question @ http://forum.mikrotik.com/viewtopic.php ... 08&start=0
but nobody from MikroTik ever warned somebody about missing 100mbit support and I'm not talking about cheap 100mbit toilet SFPs, I'm talking about the good stuff!!!
