ipolex 1000Base-LX/LH SFP Transceiver, 1.25G SFP LC Fiber Module, Gigabit Single Mode Mini GBIC, 1310nm SMF, up to 20km, for Cisco GLC-LH-SMD, Ubiquiti UF-SM-1G, Meraki, TP-Link TL-SM311LS and More

I have a few Linksys managed switches and a few "smart" switches (similar to a managed switch with no layer 3 functions or console port). They primarily use traditional copper ethernet cables, but they each have two SFP ports for fiber. In theory these can be used for any purpose, but in practice they're best saved for when copper cannot cut it. I use them for 30-40 meter runs in my home that get snaked through the garage and end up under baseboards. Fiber is really thin, so it can fit under the baseboard. Fiber is immune to crosstalk, so the various runs being right atop each other won't interfere. Of course another use for be extremely long runs or runs through an industrial area with loads of magnetic interference or other issues. Lastly, fiber doesn't conduct electricity, so it won't spread havoc if a connect device gets struck by lightning.Anyway, these SFP modules just plug in and work. I used Monoprice LC to LC fiber and these on both ends (in Linksys switches). Works great.

Needed these fast for an installation and they worked fine and arrived quickly and much less price vs OEM

This was almost a plug and play device; I did have to install the Marvel 10g driver but once that was done this was recognized immediately and performs exactly as desired in a BPI-R4. It is a little warm but not outrageous, I put a heat sink on top of the SFP port and after a couple hours uptime measured it at a not worrisome 36C.

Bought these for an Aruba 1930 Poe 8 port switch. My 10gb transceivers wouldn’t work in the sfp port, these did the trick.

I ordered the ipolex Gigabit SFP Copper RJ45 1000Base-T model and this works with my MikroTik. I had to make some changes on the OS for it to communicate with the device. If you have issues with it just seeing activity you may need to turn off the auto-negotiation feature on the port and set the speed to 1GB for it to start working. This is what I needed to do. After this it started working without any issues.So far everything is working as described and getting the full speeds listed.

I'm using these SFP plugs to go from my basement (networking room) to my study on my 1Gb system and they work well.

Plug and play. We use these with Cisco SG300-10P and SG350-10P switches.Have not had any problems with them.

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 don't 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.
