I put in fiber between the house (where the internet comes in) and the workshop (where my home office and servers are) years ago when 1mBit was the best our ISP could offer. The fiber was 62.5/125 OM1 multimode. By the time I realized that for the same price I could have gone with something better the fiber was already buried and I thought I was doomed to 100mBit forever. Recently I started to look again and found 1000Base-LX and and mode conditioning cables. I went down that path, but through a series of wrong parts shipped didn't get a fully set of hardware yet. Meanwhile I found these guys and thought I would give them a try. They worked perfectly on my existing setup. According to iPerf benchmark I get 950mBit over my 1000ft of 62.5/125 to a couple to another 350ft to the shop. I couldn't be happier with this product.

It just worked for me, as is, out of the box. Powered it up, plugged in ethernet cable to switch, the 2 (Tx/RX) fiber leads, and instantly kicked in at 1gbps speeds. Simple instructions are included if you needed them, as well.

They were a good price and I just plugged them in at both sides of the fiber and they worked perfectly. I didn't have to adjust anything or reset dip switches. they just worked.

Let me be totally transparent, I had to return this item due to the fiber being damaged, replacing the media connection was the least of my worries.The item is easy to connect and worked perfectly on my fiber jumpers.

Would be 5 stars if the power adapter cord is a bit longer.

Worked as advertised. Contacted support and they were engaging, quick to respond, and went the extra step to make sure I got what I needed and understood why.
