07-06-2025Bought the wrong GBICs for a project, and then took a chance on these because I could get them delivered quickly. So far, theyre working well. Had them live for a month.

> 3 dayPurchased to connect my Google Fiber to my Ubiquiti UDM Pro to achieve 2Gbps down / 1Gbps up. I was able to get 2 down but up was limited to 380 Mbps. I replaced it with an SFP+ to Rj45 module from Ubiquiti and reached the full 1Gbps up. Obviously, this product is not truly compatible with Ubiquiti as advertised.

> 3 dayCisco 10GBase-T SFP+. Product does not work with Cisco 3850-24XS-S, never established a link. Buyer beware this is the same company as 10Gtek.

> 3 dayI have an Aruba S2500-48P switch that has 4 SFP+ interfaces that are noted as only supporting 1gig copper modules in the manual but on a whim i grabbed this thinking if it doesnt work no big deal, but sure enough right out of the package and loaded it into the powered on switch and it picked it up and saw it without issues or additional tricks like enabling unsupported transceivers etc.. Connected to my google router and full10g works perfect on a cat6 cable! Ordered 3 more now. I havent tested jumbo frames/mtu yet but I will update if any issues.

> 3 dayOrdered the 1.25/2.5/5/10GBase-T: 30m variant. Works in my Aruba S2500-24P switch, and negotiates 10gb/s when connected to my desktop PC that also has a 10gb/s network port. Also works in my Intel X520-SR2, after enabling unsupported SFP+ devices. Tested with Truenas Core (FreeBSD), while connected to a 1gb/s RJ45 port of the previously mentioned Aruba S2500. Yes, this particular SFP+ module negotiated down to 1000base-t (1gb/s), and seemed to function fine. The point of this test for me, is that it means I can use an Intel X520 card in my opnsense (freebsd) router, with this SFP+ module to connect to my ISPs Gigapoint 803G ONT (1gb/s RJ-45 port), and a 2nd fiber SFP+ module to feed my aruba switch / LAN.

> 3 dayThis transceiver functions well and negotiates to 10Gb/s on a MikroTik CRS309, but within SwitchOS the transceiver does not report temperature like the manufacturer MikroTik S+RJ10 transceivers do.

> 3 dayWhen using this to uplink from a Mikrotik switch to a 2.5Gig router when trying to push upload of 1Gig or more the link would keep dropping. When the module was replaced by a Mikrotik official SFP+, problem was resolved. How ever using these to 10Gig devices they are fine. They arent stable for below 10gig link speeds.
