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

The product availability, quality, pricing, and performance all met our needs. In comparison to other similar products this product is a good value.

Extended home network to garage. Works great.

The manufacturer will send you spam requests for reviews.

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.

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.

With two of these paired together, they worked just fine and I got full gigabit speeds. After a few weeks I had an issue where both SFP modules stopped working so I reached out to 10gTek at their Amazon seller address. Amy was great to work with and sent me out two new SFP modules so the units are now working well again.

Easy setup and its working correctly. Thanks,

It does what it promises. I got about 930 Mbps through it, which is what I get over plain 1000BASE-T. Im a big fan of the metal case. However, the price isnt 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.

My Company have use several of these. Have Never had a problem. They Just work every time

roon core⇄Dela S100⇄インタネットという接続の⇄のところに使っています。再生機器、NAS はDela S100に直接接続しています。 このようなオーディオ機器とインターネット、パソコンなどとのアイソレーションにはかなり有効です。音質は見違えるように良くなります。 また、SFPモジュールは付属のものから、パナソニック、ELECOM の業務用のものに変更し、デュアルモードで使っていますが、SFPモジュールによる音質差は大きいので、余裕が有れば交換をお勧めします。 再生機器とDela S100の間に使ってしまうと、この機器自体のノイズが再生機器に影響し、あまりいい結果は得られないと思いますので、そこはSonore等を使った方がいいと思います。
