Gigabit Ethernet Media Converter, MultiMode Dual LC Fiber to Ethernet RJ45 Converter for 10/100/1000Base-Tx to 1000Base-SX(with a SFP MMF 850-nm Module), UL Certified, up to 550-m, Pack of 2

Excelent product and very fast install

I have two of them and they simply work well non-stop.

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.

In general this is a great helpful product if you don't want to have to program/pay for a managed switch, this is a cheaper way to get a fiber extension to your network. That being said, out of the 5 or 6 times I have used these, this is the first that arrived with a bad SFP module. Lucky I had another one at the site.

So awesome to have access to fiber technology at reasonable prices. Works like a charm!

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

Just received and installed these. Solid connection. Note that you need to cross the fibers over. A to BUnits run cool.

I live in the lightning capital - Florida. So I use these to fiber isolate parts of my network from electrical surges. (lost previous network to lightning strike that traveled over my Ethernet network). These work great, are easy to setup, and reliable.

Plug and play. Just works. Perfect.

ネットワークオーディオのために購入ネットワークがインターネットにつながっている場合は、Spotify再生である程度アイソレーション効果がありました。ただしスタンドアロンネットワークでローカルファイルを再生した場合は逆に音が悪くなりました。その程度の商品です、過度な期待はしないほうがいいと思います。電源は付属のアダプターではなく低ノイズ電源が必須。私はモバイルバッテリーを使ってます。プラグは5.5x2.5mmです。

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!

他の方の口コミを参考にして、導入してみましたが、効果はハッキリと音に表れています。音場の広がり、音の明瞭感もクッキリしました。併せて電源強化及びYouTubeでのケース交換を参考にしつつケース交換の代わりに、重しを載せる事で変化が感じられます。此方の製品を２段重ねにして、その上に重しを置いたのが、自分的には好みの音質となりました。

ネットワークオーディオでルーターとHUB・音楽再生用パソコンの間を光にしましたが、音が痩せるわけでもなく、綺麗で定位もよくなりました。ルーターからのノイズがこんなに多いと思いませんでした。値段の割に良い製品だと思います。
