[Halken]

Lots of other brands use them now. Pretty much all the 80 and 100 meter ones use it, with the 100 meter ones supposedly using slightly less power than the 80 meter ones despite using the same chip (seemingly binning).

Yes, the 30 meter ones draw significantly more power than the 80 and 100 meter ones. Unless you need the Aquantia based transceivers for some reason, I personally don't think anyone should buy 30 meter rated 10GBASE-T transceivers anymore now that the price from Chinese manufacturers has dropped so much. I managed to pick up the ZYOPM 100 meter model for $25 including 25% VAT, although that seems to have been an unusually good deal. $35-40 including VAT seems to be pretty standard though.

The thread below includes a number of other examples:

Your Chinese switch very likely doesn't care. For Intel NICs, you very likely need the transceiver to fake being a fiber transceiver, which many of them do. My XICOM 80 meter transceiver came like that by default. ZYOPM asked me what brand of equipment I intended to use it with and programmed it accordingly. Have you unlocked your Intel NICs btw.? They can be vendor locked by default.

I will be returning the 30m trans to Amz then.
I just got the E810-DA2s, and only got around to update the firmware as they run with DACs right now.

The Ali link does not show anything, and I have even trouble seeing a login page. I'll have to see what is wrong.
I can get some from Wiitek via Amz US, but that 100$ likely plus VAT. I am looking for some in Europe.

Which AliExpress link?

https://www.aliexpress.com/item/1005008504978560.html

https://www.aliexpress.com/item/1005005961638364.html (need to select 80 meter)

What if you try to find the ZYOPM one through their store? They might have multiple listings. If you still can't find it, they might not sell to your country.

Have you tried searching for the Wiitek ones in different Amazon regions that might sell to your country without massive shipping fees? Using the ASIN when searching might help.

Now it works with Ali. It did not like my DNS.

Can you post a direct link to Wiiteks 100m type on Ali? I can see the Zyopm just fine using the direct links, but their search is not so good. Thx.
The Zyopm are 84 for 2 100m incl VAT & shipping. Not bad.

 

[Halken]

So are there 2 in the mail of Zyopm SFP-10G-T 100m. Incl VAT its 85$. Not bad.
Thx for your help.

EDIT
I canceled it again as the module is 10gb only. I need one that will also do .1/1/2.5/5/10 instead.

I don't know if the Wiitek one is available on AliExpress.

The ZYOPM one seems to be eligible for their Back to School sale so you should be able to get an extra $10 off with the appropriate coupon if you click on the red line "US $10 off on US $69". If you have coins, those should give you another 5% off. If you have the same 25% VAT as me, it should end up being $68.57 for 2 after coins and coupon.

Another AliExpress tip is browse for the products you want and then check the "For you" section on the Coins page. Sometimes you come across items that are 20-60% off with coins, but only if you go to the listing through that page. I just picked up a 2 meter SFP+ DAC cable from ONTi that way for $3.12 including shipping and 25% VAT, down from the usual $10-15 that I usually seem them for.

EDIT: Oh, you needed the lower speeds too. Then the Wiitek might be your best bet, unless there was another one available in that other thread. What you could do is contact Wiitek through Amazon and ask them if they have a more local listing for you.

I've also seen someone else find a listing for an item from Amazon.com on Amazon.co.uk where they weren't charged for the shipping from the US, despite the item being shipped from there. Sure, you'd still have to add VAT on top when buying from the UK, but it might be cheaper.

Pretty good priceyou got.
I wait a couple of months and see if it does not appear on this side of the water as well.

I would've contacted Wiitek, but that's just me.

I tested the Ubiquiti UACC-CM-RJ45-MG in a QNAP QSW-M7308R-4X and didn't see any of the cold boot issues that were present in the Mikrotik CRS309-1G-8S+IN.

So my guess is that the SFP+ spec neither requires the port to be disabled during bootup, nor does it disallow TX_Disable pin from being directly connected to the PHY. These parts of the spec have probably been worded broadly enough to allow different interpretations.

Yes, it's possible that the spec isn't worded explicitly enough in that area. The fact that the transceiver in question has compatibility issues that other ones don't have is undeniable though. I therefore still consider it a hardware design issue on Ubiquiti's part, or the OEM/ODM they use of it wasn't designed in-house. They deserve credit for being the first to reduce the price of these transceivers though.

Good idea. I have written to Wiitek.

I have been testing the Wiitek SFP-10G-T-100 that I bought from Amazon one week ago. More specifically, I have been using it in a Mikrotik CCR2116 for WAN connection to the 2.5G port of an ONT with 2.5G down + 1.25G up internet connection. Flow control is enabled for TX and RX. Desktop has 10G connection to the network.

I seem to lose internet access once in a while in the upload portion of a Speedtest, despite the router never losing connectivity on the SFP side, and the ONT always reporting active connection (LED) on the RJ45 side. When internet access is lost, ping to www.google.com times out in 2/4 attempts, with the remaining 2/4 having latency of 900ms. Temperature of the module hovers between 55C - 60C. I have to either replug the module or turn off/on the ONT to get internet access working again.

Prior to the Wiitek module, I have been using an Aquantia AQS-107-CX-1 (Supermicro AOM-AQS-107-B0C2-CX) for the past two years and never experienced this issue. RouterOS reports the Aquantia module having alot of RX Pause during the upload portion of a Speedtest compared to zero on the Wiitek, so I wonder if this is a symptom of the issue. I believe the Aquantia module was one of the first to properly handle NBaseT via Pause frames.

I tested the Ubiquiti UACC-CM-RJ45-MG in the WAN connection a few minutes ago, and like the Aquantia, saw alot of RX Pause during the upload part of the Speedtest. I'll see if I experience any issues like the Wiitek over the next few days.

 

[nereith]

Following up on my previous post, I have not faced any issues with the Ubiquiti UACC-CM-RJ45-MG in the WAN SFP+ port.

My conclusion is that the Wiitek SFP-10G-T-100 is probably fine for a 10G connection, but I can't recommend it for NBaseT due to lack of support for Pause frames.

Looks like someone else is seeing a similar issue with the same Wiitek module.

Does it show up as a 2.5G connection on the Mikrotik? I've found that only the first party 6 speed modules auto negotiate correctly and I have to manually set 2.5G for third party transceivers to get them to work correctly.

Mikrotik detects the module as 10G. Download portion of the speedtest hits 2.3Gbps, so that implies the link to the ONT has been negotiated to 2.5G. Forcing the SFP+ interface to 2500BaseT or 2500BaseX makes the module undetectable.
