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

Works great. No complaints.

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.

As advertised

私は無線LANルーターとDELA、S100というオーディオ用スイッチングハブの間に光アイソレーションの為に使っています。大満足です。接続は問題なく直ぐできますし、DELAのS100だけではまだ残っていた金気くささが完全に消え、空間描写が深くなり、静かになりました。安いと思います。

The converter didnt work, but the included gbic did. The unit caused me some embarrasment when I connected it to fiber internet in front of my boss and nothing happened (copper link light came up but fiber didnt). The support was not very useful as they only asked for my Amazon order id and I have not heard from them since. On the other hand having a working sfp module really saved me today. I plugged it in tp link converter and it just worked.

In general this is a great helpful product if you dont 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.

Extended home network to garage. Works great.

Easy setup and its working correctly. Thanks,

Items delivered on time and worked with 1 GB SM SFP Modules I already had.

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
