10Gtek 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

この製品の良い所は安く手軽に光アイソレーションを試せる位しか役に立たちません。 が、やらないよりはマシになる程度です。

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 purchased 2 of these. No issues at all. Using 1 gig fiber SFPs connected to cisco switchs. They just work. Products were well packed, no damage. Very simple.ple plug and play.

I was worried that it wouldnt work with our AT&T fiber circuit, but we had no issues getting it setup and working. Throughput is amazing.

Got this to run fibre from my home office to the front room so the smart TV didnt keep buffering over wifi, so easy to use just plug and play with one at each of the fibre cable and all my buffering problems have gone.

I bought this fiber media converter to create an ethernet connection between an underwater remotely operated vehicle (ROV) and the land station controller. The fiber solved some issues for me that UTP was causing. 3 camera signals and the control connection are carried over the fiber. I selected this media converter because it was inexpensive and had the LC connectors that I was looking for. The small size was also critically important. I removed the case so that I could more easily squezee the media converter in with the mini switch.

These 10gTek media converters are missing two key features as far as I am concerned- the ability to select auto-negotiation or force duplex settings, and they do not propagate link state from copper to fiber and vice versa. Like it or not- a lot of providers force the speed and duplex settings on their connections. Without the ability to force these settings- these converters would not work with my service providers. If you are just connecting two of these devices together to traverse a distance- then youre probably fine- but if you want to work with other devices- you could run into problems. The second issue is far more serious in my opinion. 10GTek seems to have implemented these converters as a simple 2 port switch. What that means is that you can plug a cable into the RJ45 connector and you will get a link even if there fiber is down (or disconnected entirely). If you want to track interface status for something like HSRP, or if you want BGP to fail over immediately because the link went down- youre out luck. Your BGP session will have to time out before it fails over which is less than ideal- and interface tracking wont work at all. As an alternative you should consider the TRENDnet TFC-1000MGA or TFC-1000MGB instead. Both of these devices correctly relay link state from copper to fiber and vice versa. If the fiber is down- the copper interface will be down. If the copper is down- the fiber interface will be down. You can also force speed and duplex settings or leave it to auto-negotiate.

Works awesome

Quality item. Im happy i got it. exactly what I was looking for

Not an Ethernet to fiber media converter. Fiber media has a different connection to a TV, receiver, or even a Blu-ray player.
