I had 125' LC to LC fiber laying around that I wanted to put between my cable modem and router.I purchased two of the 1.25Gb/s SFP Module to 10/100/1000Base-Tx, with a 1.25G 850nm 550M SFP media converters and plugged one in on each side and connected the fiber. I removed my 50' ethernet cable and plugged a 3' one directly between the cable modem and media converter. I did the exact same thing on the other side and everything came up immediately. Lost a total of 5 pings, and my routers IP address did not change. (the cable modem has no idea these are in-between).As far as a performance test goes, my average ping time to my cable modems default gateway may have went up by about .25ms average over 100 packets, but that could just be the neighborhood I am in.I am more than pleased with this simple solution to protecting my network from a lighning strike on the cable lines around my house.Also - I purchased a 3rd one as well as a 10Gtek for Cisco GLC-SX-MMD/GLC-SX-MM/SFP-GE-S, Gigabit SFP SX Transceiver to plug directly into my network switch. I just trenched a 6-10" trench to my shed and will be placing the media converter in there along with an access point which is about 80' from the house plus about 35' of internal cable. I have already tested the 3rd one along with the SFP module in my switch and they connected right up. As long as I dont have any issues running the fiber, this is another great use for these to protect my internal network from both near lighning strikes as well as static differential between the buildings. While I cant take advantage of POE (Power Over Ethernet) to power the aceess point, I think the isolation definatly outweighs the benefits of POE.So far I have less than 30 minutes with these in use (2018-10-21). If you dont see an update from me, they are still working.

Great product, the included SFPs are worth about 3/4 of the product. Love that it is a direct wiring so there is no extra latency or conversion involved. Has been working great to convert my RJ45 wall keystone to fiber so I can run it next to power in the office without concern for interference

It does what it promises. I got about 930 Mbps through it, which is what I get over plain 1000BASE-T. I'm a big fan of the metal case. However, the price isn't the best. You can get one without an SFP transceiver and just buy your own transceiver off eBay. Cheap ones are plenty fast enough, and I found a 4Gbit one for less than $2 including shipping. The TP-Link alternative is about the same, metal case and all, but cheaper if you add your own transceiver.

Used in an audiophile system, the 10gtek, for me, was plug and play. Super cheap and easy to run long stretches of unobtrusive fiber. Transceiver compatibility might be an issue, so try and find component combinations that have worked for others.

Upgraded lower performance unit works well

I am using two of the media converters connected together with a short one meter fiber optic patch cable to provide Lightning isolation Protection to my local Intranet after sustaining several destructive Lightning events that came in over my under ground telephone/ DSL cable. The system is working well and I see no speed reduction.The 10Gtek converters are well made and impressive in their small size, zero configuration, and low cost. What more could I ask for. I would recommend them.Ken. KB6KKW

I have purchased 4 of these in the past, along with multiple 10 packs of their SFP+ Fiber connectors. Initially, the quality was great, and they worked like a charm. The last batch I ordered came with a more generic looking label on the SFP and Ethernet, fiber modules. The first two did not work at all, I swapped in my own Ethernet Modules and the unit would work, however, the Ethernet release mechanism on one unit didn't work (ended up breaking one of my own Ethernet SFP module levers. As a result I asked for a replacement return. I got the next two units, and while they do work, the Ethernet modules do not want to release like the first ones. If I was guessing, I would say they either cheaped on this, or switched manufacturers, sadly. I really was tickled with the product up to this point. I attempted to contact the company and got no response. So, I suppose it's time to shop for better quality product.

I ordered 4 of these devices as I needed 2 fiber runs joining in the middle with a switch. I was trying to address a bandwidth issue with my existing powerline adapters trying to play Blueray movies from my NAS. All my issues were resolved, and from the furthest point, I am getting less than 0.5ms response to the router. Very much plug and play, highly recommended!
