product from H!Fiber. These modules have some connection issues where the RJ45 plugs do not always snap into the socket on the module. There's no audible click, and the cables often won't engage and will *pull* out if you don't attach them properly. I've experienced the same thing with 2 other brands in the same price range (Ipolex and 10Gtek) and yes I've tried other ethernet cables - same result. They will not work with the Mikrotik CRS305 line of products. RouterOS reports these modules (and another brand in the same price range) as OEM SFP-GE-T devices. I tried them on RouterOS v7.1rc3 (testing) and v6.48.4 (stable). Same result. The only ones I haven't had any issues with are the QSFPTEK 10GBASE-T SFP+ modules, which is very unfortunate as I don't need a 10Gb RJ45 for my use case and at the time of writing it's around $44 per module . I will post this review on other devices that I have purchased and tested.
