Check out Rohit's main site article with the full guide that we will update if and when we get more modules tested. www.servethehome.com/sfp-to-1...
In this video, we discuss the results of testing the top 9 SFP+ to 10Gbase-T adapters that we found on Amazon. Note, most of these are coded for Cisco, but we are assuming using switches and network adapters (NICs) that do not enforce strict SFP module coding such as QCT, Edgecore, Celestica, Delta, and MikroTik switches and most Supermicro products.
We summarize the results of our power and performance testing while also uncovering some undocumented features such as testing Jumbo Frame support as well as 2.5GbE and 5GbE or 2.5Gbase-T and 5Gbase-T support.
We also look at why these may be called Cisco SFP-10G-T-S modules even though there is no current Cisco module with that title and how some of these units may not have all of the markings they should.

"Do they support jumbo frames?" - the only valid answer to that question is "No, they don't.". They also don't support VLANs or BGP or HTTP/2, because they are Layer 1 devices and don't care what the bits they transport actually mean.

@AlexForencich 3 года назад

That was my initial thought as well, however jumbo frames could potentially be an issue. These contain PHY chips that could potentially do some retiming and idle insertion/removal. Jumbo frames mean there are fewer opportunities to insert/delete idle control characters between frames as the frames are 6x longer than 1500 byte MTU frames, and as such jumbo frames could possibly cause some issues. As for the other stuff, that's just data in the frame, so it's irrelevant from the standpoint of the PHY chip. The bigger question is why is there any difference in speed at all, since these are physical layer devices.

@JasperJanssen 3 года назад

@@AlexForencich the fact that there is a speed difference means that in fact they’re *not* just PHY devices.

@AlexForencich 3 года назад

@@JasperJanssen They are PHY layer devices, SFI/XFI on one end and 10GBASE-T MDI on the other end. The interface on both sides of the device is physical layer, which must operate within around 100 ppm of the specified line rate, otherwise the link will not work at all. Unless this is injecting pause frames or something towards the switch (which they should not be, but it should be possible to rule this out), the only possible cause for a speed discrepancy is packet loss, either due to signal integrity or differences in the FEC decoding. 10GBASE-T uses an LDPC FEC, and it's possible that some of the modules do not implement the LDPC decoding correctly/completely, resulting in more bit errors and hence more dropped frames on some modules. What I would like to see is a dump of the switch packet counters (tx, rx, fcs error) from both ends of the link during these tests, that may shed some light on the discrepancy.

@jaytfo 4 года назад

The modules have only PHYs to covert typically XFI to xBaseT. The newer PHYs tend to support NBaseT, where the older ones did not. The newer PHYs 'should' also be slightly lower power. For performance, it's almost SOLELY based on cable performance, how well it can get the signals down the wire and reject CM. As for other things like Jumbo frames, typically PHYs don't discriminate anything over L1 (some exceptions apply). Going back to the host interface, another thing to look at is if the modules solely support XFI using flow control to support the lower speeds on the line interface, or if they support USXGMII, which is also a 10G interface (the same interface actually @ 10.3125Gbs & 64b/66b), but support the lower rates by multiplying the data (like how SGMII runs 100Mbs, still runs at 1.25Gbs, but duplicates 10x to slow it down). I would have been very interested in knowing which host interfaces these have, and for the future the same applies to switches with SFP+ (XFI only, or USXGMII). The final part you're missing is cable performance, you should try short and long cable, and also see what the limit is. Thanks & cheers

@scottxiong5844 4 года назад

@llynellyn 3 года назад

Worth noting that the reason the Mikrotik S+RJ10 use a little more power than the other adapters is because they are enhanced range adapters, if you have one at either end then the cable run can be up to 200m for 1GBe or 2.5GBe (instead of the regular 100m).

@shmayazuggot8558 Год назад

Great review, the only addition I would consider here is choose lower wattage over everything else, especially if the longer term goal is to populate most of the ports. 20x 10GBase-T ports at .4 watt more sure does add up in heat and power draw. Also for the more serious consumers, get fibre where possible as the power draw is considerably less. Also fibre has much lower latency than 10GBase-T 6x10Gbase-T ports has a latency of ~15 opposed to 0.6 with fibre. On my router 10GBase-T port reports ~54c and the 10GSFP SMF fibre reports 32c. that's a whooping 20+c per module difference, thankfully I only have two Base-T modules the rest are fibre.

@MikkoRantalainen 2 года назад

Great comparision! One thing you could have measured is latency over these adapters. If I've understood correctly, high quality SPF+ to 10GBase-T adapters should cause about 25 µs extra latency over fiber and it would be interesting to see if the cheapest models cause more.

@blendonator 4 года назад

I would be curious to know what transceivers work fully on Cisco switches, namely in terms of if it can check temperatures and other various stats, properly

@SomeRandomPerson 3 года назад

Just FYI - I got some of the Wiitek 10G-BaseT SFP+ modules today, they've got an apparent manufacturing/configuration date of 2021-03-30, and come with country of origin (Made in China) markings on the box and module. As for temperature, after a few minutes they're as warm as the 10G-BaseT SFP+ modules I got from FS - reporting about 50-54C in my Mikrotik CRS309-1G-8S+

@FlaxTheSeedOne 4 года назад

Also a nice information i figured out the hard way. They are Hard capped at 30M wire length if the other device on the other end is a low power device like the Asus U2008 10g Switch. If you use an INTEL NIC on the other end with a 100M power output capacity it works fa some longer ranges about 40-50M. But that is one thing to consider when using these module with other low power devices on the other end that you may not be able to wire through your entire home. I would like to see some more imperial testing on your end if you could, i can just speak for one or two runs i made through my home which exceeded 30m.

@ServeTheHomeVideo 4 года назад

We did testing in the reviews of longer cable lengths, however, these are all rated at 30m. Going beyond that there are a lot more variables.

@Ballebek01 4 года назад

My own tests show 45 meter is the maximum (with Cat5e cables). My longest Cat5e cable here in my house is 30 meters and works perfect with 10Gbase-T. Off course when you are a little less Scrooge, you can use Cat6a.

@jaytfo 4 года назад

The generation of PHYs used within these modules, would draw too much power from the cage if they supported over ~30M. We should start to see that change in the coming future.

@stonent 4 года назад

We were recently troubleshooting an issue in a Cisco switch and we noticed one of our modules was throwing an overheat warning in the logs. We focused on that module and it turned out we had inadvertently installed a cheap module that came with some other hardware in the Cisco switch. There ended up being nothing wrong with the module, other than it did not support temperature reporting to the switch, so it was making a lot of log entries that were distracting. So that's another feature you need to be on the lookout for, is will it report temperature to a switch that wants temperature information.

@Dycell 2 года назад

The reason they note the ‘Cisco’ model number on their advertising is because allot of Cisco switches won’t accept ‘non-Cisco’ SFP modules. They just refuse to ‘enable’. After some protest by (home) users they developed a config option to make them work. They still generate warning and error logs in the device. At least, that’s what was happening 5 years ago (when I did networking). We even had a supplier that flashed specific Cisco firmware on the SFP to avoid warranty discussions or deployment issues.

@cdoan82 4 года назад

Food for thought, if you plug a Cisco compatible "10GbaseT" SFP+ into a Cisco switch and run "show inventory" or "show interface status" it will come up as a SFP-10G-SR= module, a multimode LC fiber transceiver. Yeah it's spoofing the switch with another model and probably won't matter in the home but if run in the enterprise environment, it's not technically "supported" but I doubt Cisco TAC will even find out.

@jfbeam 3 года назад

They will when you give them the "show tech" output. (if they look, and their scripts do.) At worst, they'll tell you to put "genuine" cisco optics in it. (which is of course bunk, as Cisco doesn't make optics... they have manufacturers add the required signature to the flash. And there are 64 possible signing keys -- the code's been known for a long time.)

A transceiver works at the physical layer (Layer 1 OSI model) and frame size (hence jumbo frames) is a property of datalink layer (Layer 2 OSI model), right? If that is the case, I cannot imagine how any transceiver could be capable of not supporting jumbo frames.

@mdocod 4 года назад

In my estimation, the difference in power dissipation was probably more to do with variances in component tolerances. Keep in mind that many of these "cheap" off-brand SFP+ units are likely built using the reject IC's from an assembly line that supplies IC's for a major brand name like Cisco/HP/Etc, so while they are still functional, some are over certain thresholds to go into the good bin. With regards to the fact that they appeared to be grouped up as 6 and 3 with similar functionality, I'd be willing to be that this test of "9" SFP+ modules was really a test of 2 modules with 9 different brands slapped on them.

@ServeTheHomeVideo 4 года назад

As mentioned in an earlier comment, that was something that we thought at the outset. It turns out all nine modules had different PCB/ markings near the exposed part by the SFP+ connector. The chipsets may be similar, but at least the PCBs are different.

The 3 slower ones are probably based on BCM chips, while the faster ones are AQC. The AQC chips are faster because they do less DSP and hence has shorter latency, while the BCM ones do more DSP and introduce more latency. The BCM chips do more DSP not for no reasons. The BCM chips are rated for 80 meters over CAT6A, while the AQC chips are rated for 30 meters. Test with longer cables and see if this is the case.

@btudrus Год назад

what about the power consumption? can it be that lower latency leads to higher power consumption?

@bskull3232 Год назад

@@btudrus No. Processing costs something, in this case, silicon area and power consumption. First (AQC10x) gen AQC is hot because they used an older process node due to lack of funding, just like many startups. The second (AQC11x) generation should be better in this regard.

It'a a common knowledge that those "cisco" or other claims on listings are ment to says for what vendor it can be encoded. It's actually a good thing, it makes it easier to find whatever you want. So there is no myth, it's common knowledge ;-] From all of the people you should know that.

Would have liked to see a price graph in there as well so i dont have to click every link to get the price.. or maybe that was your intention ;)

@ServeTheHomeVideo 4 года назад

We thought about that. The problem we saw while doing this series was that there were modules we purchased at $35 then they would be $55 two weeks later, $48 when we did the review and so forth. They moved so much we stopped putting that information in reviews. That is why we recommend just searching whenever you need them.

4:19 This is even weirder question and answer them previous one Your results are pointing to bottleneck at either CPU or RAM or NIC/CNA level Assuming 9000b jumbo frame you should get 1184MB/s, not 800MB/s Use faster glorified calculator for benchmark next time. SFP have no influence over performance (speed wise)

@tomkeuper7784 4 года назад

Latency?

@WizardNumberNext 4 года назад

SFP have nothing to do with Layer 2 or Layer 3. It is up to NIC / CNA to support Jumbo Frames. Your question was asked in wrong way. Effectively you are asking if specific Optical Fibre Cable or UTP/STP/SFTP cable supports Jumbo Frames. This rather weird question. Especially taking in account that you can use your OM4 cable to transmit Fibre Channel only. Does it support Jumbo Frames? No, even though it is physically possible to transmit Jumbo Frames over OM4 cable. Does OM4 cable support NVME-over-Fibre-Channel? This as wrong question as yours

Hi, where can I buy this modules for 30,40,50$?

@mikkelbreiler3846 3 года назад

I don't need one but I watched the whole thing. I blame Patrick. And RU-vid. And myself too.

@omfgbunder2008 2 года назад

The mikrotik one only does jumbo frames at 10gbit

@lowfat32 3 года назад

To anyone looking @ using these for 2.5G/5G. I'm not sure I'd buy any except the Mikrotik one. With the Ipolex and likely the other Marvell-based ones, you'll get a 2.5/5G link but the module only broadcasts 10G and real world RX performance is pretty bad.

They don't market cisco part replacements but they market cisco compatible firmware / deviceid,

All power consumption of 10Gbase-t SFP+ are greater than 2W that MSA required. They could cause hotter.

How did you miss 10GTek?

We did that as well www.servethehome.com/10gtek-asf-10g-t-10gbase-tx-sfp-to-10gbase-t-module-review/

The Transceiver market has been experiencing a long deserved correction for the past couple of years. The pinnacle of this development is what Flexoptix has been doing. Sure, in an enterprise setting, it's most of the time not feasible because you can easily lose support for the whole solution just because you're running third party transceivers. But in a small business setting, or in a homelab, they're a total gamechanger. I've installed at least 200+ transceivers, DACs and AOCs from Flexoptix for dozens of customers at this point, and they've always worked flawlessly. The programmability is key. But in most devices, they also work out of the box. Which is very fortunate, because the FlexBox programmer that is used to program transceivers, DACs and AOCs cost an absolute fortune. If you've got it, though, you can install thousands of transceivers for each about 1/10th of the cost of the original product (for 10G SFP+ SR transceivers).

I'm super confused... I just don't understand why I would need these adapters. I'm considering the purchase of a 10 gb Ethernet switch or a 2.5x8 + 2 gb Ethernet switch. These adapters just muddy the in my case.

The Wiitek actually has a China Export symbol on it.

@bradleygibson1137 3 года назад

I was really surprised that it seems you didn't end up with a few that just ended up as re-badged from one manufacturer , are your really saying that ALL the 9x units were of unique design and manufacture and that none of them were actually idenical ?

@ServeTheHomeVideo 3 года назад

There are a few rebadges as the data set has grown. For example, the Ubiquiti UF-RJ45-10G units seem to be very similar in components (yet different markings) to the older designs from a number of lower-cost 6COM, QSFPTEK, ADOP, FlyFiber, and Wiitek units. See www.servethehome.com/ubiquiti-uf-rj45-10g-sfp-to-10gbase-t-module-review/ - The general sense is that we are seeing two different generations of chips inside with the newer ones supporting 2.5/5G as well.

@craighames6282 3 года назад

No response from Cisco? If some manufacturer was using MY trade-name to advocate use of a particular product (presumably without permission), I'd be a bit perturbed!

@whatevah666 3 года назад

Yeah the tricky part about sfp(+) modules is that it's hard to know if the switch itself will accpet it, at least i know that some older (cisco) switches were damned picky about what they accepted, perhaps the situation nowdays is better overall across brands ?
