Hi, all. Recently, I am going to buy 10G SFP+ copper transceiver or 10G SFP+ DAC cable for my CRS226-24G-2S+RM. When I was looking through the webpages, and I occasionally found this https://mikrotik.com/product/s_rj10. It only needs $65. Comparing to the C2G, FS.COM, Amazon, which are around $300, that really saved a lot. And check on that link, u would find it supports distance up to 200m. That's so fantastic. How can a copper transceiver arrive a distance up to 200m?

And how can the copper transceiver arrive so long? Is it reliable to buy?

Any idea would be great appreciated.

According to the product spec, S+RJ10 can operate over 10 Mbps, 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, 10 Gbps up to 200m. I wonder, it is possible to support up to 200m in 10G copper network? After all the 10GBASE-T modules from Amazon, C2G, FS.COM can only operate up to 30m over 10G Twianx cables.

Stop questioning

I suppose you can only buy and try it out. The other Mikrotik SFP's work great, though we buy all our SFP's from FS as it is much cheaper in bulk than our local suppliers.

Open the brochure, there is a distance table inside. You can see what speed you can expect for some distances:

Does anybody know when we will have US availability of these? Can't seem to find them anywhere.

200m between a pair of these at 1Gbps, or at 2.5G using STP cable. They do 10G only up to 30m so be mindful of where you want to use them.
They seem really nice though, and for that price it's really good if you want a 200m link using copper.

They was just announced a few days back,

You should start seeing them at the suppliers in the coming weeks.

I'm actually very exited about this product.

We have an issue at one of our sites where there are a few wireless providers on the building and they like to "accidentally" damage one or 2 of our up links going to the core.

10G over copper @30m will be way more durable then even armored fiber cables.

It doesn't support jumbo frames. That's 100$ cut from price. And improperly autonegotiates to non-10G speeds. That's remaining 35$ from price and voila - from 200$ to 65$

Plus it probably has 'meh' compatibility. Other MikroTik SFP+ modules I use didn't work with Intel X710-DA4 network card for example while other manufacturers make more universal modules.

3.Is it possible to use CAT.5E cable to link with 10GBASE-T?
A: No. The standard bandwidth of CAT.5E is 100MHz, and CAT.5E is designed to transmit signals below 90M. 10 Gigabit signal transmission requires a CAT.6A patch cable.

10GBase-T will work even with Cat5e as long as the distances are short.

Transmitting signals successfully always is a combination of cable quality and distance.
