Works as expected in my Cisco C2900XL switch

This review is for the Gigabit SFP to RJ45 Copper SFP Transceiver, 1000Base-T Mini GBIC, 1.25G SFP-T Copper... product from Ipolex. As one other user review noted, these modules have some connector issues where the RJ45 male connectors do not always click into the female receptacle on the module. No audible click either and the cables often do not seat and *will* pull out if you don’t wiggle them into place. I experienced the same thing on 2 other brands in the same price point as well (H!Fiber and 10Gtek) and yes, I tried other Ethernet cables - same result. They do not work on the Mikrotik CRS305 product line. RouterOS reports these modules (and another brand in the same price point) as OEM SFP-GE-T devices. I tried them on RouterOS v7.1rc3(testing) and on v6.48.4 (stable). Same result. The only ones I have had zero issues with are QSFPTEK 10GBASE-T SFP+ modules which is unfortunate because I dont need 10Gb RJ45 for my use case and they are about $44/module at the time of writing this. I am going to cross post this review on the other devices I purchased and tested as well. I am disappointed in Ipolex (and 10Gtek for that matter) because I have used them in the past and they have worked fine.

This worked perfectly in my Cisco 3850 switch. Nice

Cables worked as advertised.

Needed a couple of these to extend network with a downlink between two UniFi switches. Excellent price and received them quick. Link has been up for about 2 weeks now with no problems!

Works very well, wil;l buy more.

Good price and works as advertised. Tested links at 1, 2.5 and 10G

Worked great in my ubiquiti unifi 48 port switch in the sfp+ port. Used to get 10g speed to my dell servers 10gig copper ethernet port

Great price for a 10G SFP+ RJ45. Works just fine in a Zyxel XGS1250-12 switch. I have my Mac Studio plugged into it and Im getting a rock steady10 Gbps link.

Used in a Netgear GS316EP…works as expected.
