Gigabit Ethernet Media Converter with a 1Gb SFP SX LC Multimode Module, 10/100/1000M RJ45 to 1000Base-SX, up to 550m, with a British Power Supply

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.

コンパクトで、LCコネクタを接続するコネクタが金属でできており、光ファイバケーブルの保護的な役割をもっているので、ケーブルの取り扱いが非常にしやすいです。 大手メーカーの1/4程の価格で、コストパフォーマンスも素晴らしいです。

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

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。

Great product, very easy to use
