10Gb SFP+ RJ45 100m

[hellome]

My Wiitek UF-RJ45-10G-100 has arrived and I can confirm that it seems to work fine in my Solarflare SFN7322N card. What's more, it seems to run quite cool with just a 2m cable:

OK, I ordered two examples from AliExpress and will report back how they work (performance and temperatures):

• ZYOPM: https://www.aliexpress.com/item/1005006875162404.html (the 80 m variant), just because they are reasonably priced and reviewers tell, they are not running that hot. Also asked the seller about temperatures and chipset: should be cooler and have Broadcom chips - let's see. USD 25.55 after Blackfriday discounts
• NVOC: https://www.aliexpress.com/item/1005008119459901.html (100 m), this is the NVOC discussed above. USD 50.19

OK, I received both modules and with some preliminary testing, it looks good in my Mikrotik 309 - they both run approximately 50 °C idle - same as my fiber modules. When I should guess, the NVOC probably runs 1-2 °C cooler - but it fluctuates much more than the other, perhaps the reporting interval is higher on it.

It is probably a bit difficult to compare to your numbers, as we have different network gears and additionally I have mounted my Mikrotik switch vertically with all ports up (so heat is building up on front panel where all sfp transceivers are located). But I'm happy with both so far, when touching they feel warm but not overly hot - so I guess the ZYOPM with USD 25.55 is probably a good price/value.

I will do proper speed test in future and also try to place it on some other network gear I have (Mellanox-3 on my workstation and a BananaPi R4, which I use as a router).

I saw a post on reddit that said that these 80m and the 100m are the same chipset but they are just sorted for performance. It'd be nice to have that confirmed by someone else who knows about these things. If that's true I'd expect their temperature performance to be comparable at most short distances

Does the ZYOPM one negotiate at lower speeds such as 2.5gbps, 5gbps, and 1gpbs? I have a wiiktek broadcom one that does negotiate at 2.5gbps and wanted to see if the ZYOPM one does too before purchasing

interesting! The Amazon listing says it doesn’t but it did for me in my test (sample size of 1 to a 2.5gbs lan card in my docking station — chipset unknown)

Hello. I have been following this thread. I pulled the trigger on a couple of ZYOPM 80m this morning on Aliexpress.

Before the purchase, I tried talking with their support and I pressed them to figure out the the differences (they all sell 30m, 80m, 100m) variants.

What I got is that that
- 30m version uses AQR113
- 80m version uses BCM84891L
- 100m version uses BCM84891L but has a better PCB circuit and consumes even less power.

So there's that. It's hard to tell how much truth there is because sometimes you talk with sales people who don't understand or intentionally or intentionally misleading.

They all say that it doesn't support 2.5G/5G. Even though the Broadcom website says it does.

There's also BCM84891 (non-L). From what I gathered, I don't think it is older/newer than BCM84891L. It's just a different size/format of the same chip.

I have a few 10Gb SFP+ RJ45 Modules

ATS SFP-10G-T
30M Aquantia
10M 100M 1G 2.5G 5G 10G
Wol Works
Runs Hot but runs well

Xicom SFP+-10G-TE
80M BCM84891L
2.5G 5G 10G
Seems to link at lower speeds if forced but doesnt pass traffic
This is fine to link to another switch no good to link to a pc that needs wol
Runs cool

PACBTECH PAC-10G-T80
80M BCM84891L
10G
Seems to link at lower speeds if forced but doesnt pass traffic (only 10G works)

This one is useless
Cannot link slower to cool its self down in an emergency
if the PC goes into S3 and negotiates a slower speed
10M 100M 1G 2.5G 5G the pc thinks wol will work
but the module wont pass the traffic on

I returned the PACBTECH one and aliexpress tried not refunding me
PACBTECH said the return wasnt as described which it was
luckily i recorded the whole return process and took it up with paypal
When i tried to message them PACBTECH had blocked me as soon as i started the return process..

I managed to get the cost of the module refunded
but aliexpress refused to refund me the £4.30 return cost
stating lack of evidence
even though i provided photo + video documentation
including the receipt from royal mail with tracking and cost

avoid this one

The Xicom one is solid if you are fine with 2.5G 5G 10G only

The ATS one is very good but runs hot

Im tempted to stick with Aquantia until we get confirmed working at all speeds 80M/100M modules

After reading more on the subject, I think I have a better grasp on the why some speeds may not work.
To begin, there is no NBaseT in the SFP world. The manufactures use NbaseT PHY and try to make them appear as fiber optics ones.
To make different speeds work, there are two ways:
1. Always emulate 10Gbase-SR and inject an appropriate number of empty frames when connected at 5/2.5/1 etc.
2. Emulate 2.5Gbase-SX when 2.5G, Emulate 1.25Gbase-SX when 1G, and so on.

I believe 1 is the method employed by the 30m Aquantia based PHY.

It appears to be possible to program the 10GBASE-T SFP+ transceivers to appear in a way that at least ethtool identifies as "Extended: 10Gbase-T Short Reach". Most transceivers will fake being a fiber transceiver because that increases compatibility. For instance, some NICs refuse to work with 10GBASE-T transceivers unless they claim to be a fiber transceiver.

I wouldn't necessarily call it "emulation". It think it's mostly just spoofed EEPROM data.

What people say about the Aquantia ones is that they use pause frames for rate limiting. Whether that's true or not is not something I've confirmed personally.

Interesting. I've never heard of them either. One thing that isn't clear to me is if VAT is included in the price. My guess would be no, but they clearly change the currency based on location, so they could certainly be factoring that in. Would be useful to know for EU buyers.
