10Gtek [2 Pack 10Gb SFP+ RJ45 Copper Module 30-meter, 10GBase-T SFP+ Transceiver Compatible for Cisco SFP-10G-T-S, Ubiquiti UniFi UF-RJ45-10G, Netgear, Mikrotik S+RJ10, TP-Link, D-Link

Runs hot but I believe that's normal for these things, I'm using it for my Ubiquti DR7 to free up a LAN port.This 10gbe variant is no doubt overkill for an rj45 cable but, I figured it leaves lots of head room for future upgrades and getting 2.5gb down an ethernet cable in a few years probably won't be much of a stretch, I also figured if a 10gbe unit isn't running at 100% it would run cooler, but I'm not sure this logic panned out as it's very hot.But most importantly for this has added no noticeable latency to my connection, it around 8ms prior and checking the logs on my router now my ping for the past 24hrs has been 7-8ms... And researching transceivers seems to suggest it adds nanoseconds worth of latency which doesn't even register on an ms scale.So all in all, happy with my purchase and freeing up an ethernet port on my router in the process.

Product1 10Gtek 30M - This product is overheating like nothing I've ever seen. This module is reaching temperatures above 85 degree during idling. Returned and bought 10Gtek Sfp+ 10Gbe 80M Doesn’t overheat and works perfectly fine with my Unifi Cloud Fiber. Superb

These work great with Unifi gateways and switches

Just the job - runs much cooler than the 1.25/2.5/5/10GBase-T version that ran red hot! In my case, it's at the top of an unventilated cupboard and its reported temperature is ~52C in mid (warm) spring.Telemetry is reported by the Unifi device it's plugged into.Cable is approximately 50m of CAT 6 and holds a steady 10Gbe, no stability issues.

hadn't heard of this vendor before, but very happy with functionalityworks reliably in a unifi setup

I've used a lot of 10Gtek transceivers now but this one just misses the mark for me in a couple of areas. I needed to connect a 2.5GbE device to a Mikrotik CRS309 switch and although this transceiver is detected fine and works for 10GbE it simply won't negotiate at 2.5GbE regardless of what settings I tried. I also made sure I purchased the model that was suitable for Mikrotik devices, because some of them aren't.I purchased a Mikrotik S+RJ10 which is essentially Mikrotik's version of a 10GBase-T transceiver and was significantly cheaper than this 10GTek one. The Mikrotik S+RJ10 negotiates to 2.5GbE fine and it also has DDM which means it reports the temperature of the transceiver etc. back to the switch.It's worth noting that this transceiver works perfectly at 10GbE, and like other transceivers running at 10GbE it does get pretty toasty.Unfortunately this 10GTek doesn't work so well for me with Mikrotik devices which is a real shame.Pros:- Compatible with a large number of devices- Works perfectly at 10GbE.Cons:- More expensive than similar products from other manufacturers- Doesn't seem to negotiate 2.5GbE properly on Mikrotik devices- No DDM support (monitoring of transceiver temperature etc.)

Has been running reliably at 10G in a Mikrotik CRS309. Runs at a relatively cool ~53C (compared to Mikrotik S+RJ10 which runs at 95C+). The module reports temperature, voltage, tx bias current and tx/rx power correctly to RouterOS.The module reports its part number as SFP-10G-T with a manufacturing date of 2024-05-28 and vendor revision 02.I did not need to change any of the autonegotiation settings on either end - both set with autonegotiation enabled and a 10G link was negotiated automatically.

I got this SFP+ Module to be used on my MikroTik Router, sadly this is defective and any slight movement of the Ethernet Cable it drops link, the module still stays connected to the router, just the Link Connection is dropped.I have a 4 year old 10Gbit (only) SFP+ Module that works fine, I just wanted the 1/2.5/5Gbits Link Speeds.This points to a faulty RJ45 connector on the Module and will be contacting Amazon to return this item for either a replacement or a refund some time this week.There for due to I was unable to even test this module I give it a 1 Star.
