10GTEK SFP+ to RJ-45 10GBase-T Transceiver, 10Gbe Copper SFP+ to Ethernet Module for Intel E10GSFPT, TP-Link TL-SM5310-T and More, RJ-45 SFP+ CAT.6a, up to 30-Meter

My switch has 2 10 Gig ports I thought I would never be able to use, they were for connecting switches together. Now they are connecting my 2 servers to all of my other devices, with maximum throughput to all of my computers. All I did was add an inexpensive pcie card to the servers and away it all went. Plug and play. Amazon has a return policy, and you could buy them to

There's even HIGHER speeds nowadays, but to be frank, few of us can really use much more than a gigabyte of connection capacity as it is. If you DO need more, I found these to be an excellent option short of 40/100Gbe QSFP links and other crazy stuff like that.These were for my Mikrotik CSS326-24G-2S+RM switch, and my Arista '7050S' SFP switch. I've had no issues, and so far these transceivers work at a decent temperature for my uses. I haven't packed my 7050s full of these lasers to see how they get at high density, but so far they seem to run nice and cool. It even offered me 'laser strength and attenuation' options in my 7050s's 'advanced transceiver configuration options', but I didn't dare go messing with anything. THAT level of uber-tuning is beyond my needs, skill AND knowledge...but it DID offer laser strength options and stuff when I queried them once for my lulz.I've owned these for over a year now, and none of them have failed on me so far, for whatever that might be worth!

I installed this module in my Aruba 2920 switch, and it connected with an inexpensive thunderbolt 2.5gbps adapter with no issue (https://www.amazon.com/dp/B0C2H9HVH3). On the switch side, it shows to be coded as a SFP+SR transceiver. I reliably get 2.3Gbps using iperf.

Excellent service as usual.Attractive price, Quick delivery (ahead of Amazone estimation) , Product effective and compliant with Aruba model as advertised.

10Gtek is my default brand for transceivers on the cheap. They are reliable and compatible, which is what you should expect from such device. This one works well in my pfSense box with an uplink to ONT for a while now. Highly recommended.

I bought these for my Dell PowerEdge R630, which has an embedded X520/I350 network card with dual 1G Ethernet ports and dual 10G SPF+ slots (Intel 82599ES controller).I have bought many, many 10Gtek SFP+ transceivers over the past several years (primarily for MikroTik devices), and I have never had a single problem with them.However, this is the first time that I bought a pair of these that came in a nifty little tin. Completely unnecessary, but a nice touch nonetheless! The insides are removable, so you can use the tin for anything you want. Neat!

A few days ago, I received an email from 10Gtek asking if I could write a review for this item. Since I can login my CRS210-8G-2S+IN and retrieve the SFP+ info from this module, I'll write a quick review that confirms that this module shows up in my CRS as an actual S+85DLC03D using the console command "/interface ethernet monitor [f]". That will also show lots of other useful info, such as the sfp temperature, maximum link length (80m for 50um and 30m for 62um), and that your rx and tx powers that are within spec. This module typically runs about 1-2C warmer than the CRS itself (it is at 44C now) and has been running fine for several weeks with only passive cooling.I bought the Cisco 10Gtek module for my Netgear R9000 as well on a recommendation and figuring that I already had one 10Gtek module that I'd use them for both ends (since Mikrotik parts are typically sold through a 3rd party in the US anyway). I'd write a review of the Cisco equivalent module as well but since I can't yet login the R9000 until I put DD-WRT on that I'll hold off a bit. Just letting you know to give 10Gtek a try for your Mikroik if you're on the fence as for all practical purposes mine thinks it is a Mikrotik module. It works with both the stock (older firmware) and the latest 6.40.3 (stable).If anything changes here I'll update the review. Otherwise I still have a great 10GB link between upstairs and downstairs through 50m of OM3 MMF. :)I bought both SFP+ modules here on Amazon; none were provided for this review.
