Gigabit Multi-Mode LC Fiber to Ethernet Media Converter with A SFP SX Module, 1.25G Fiber to Copper RJ45 Media Converter, 1000Base-SX to 10/100/1000Base-TX, MMF, Transmission up to 550 meters/1804 ft

I need a lightning break between the cablemodem and my expensive router. Using this and a fiber switch I had lying around. Works fine.

We have a digital billboard outside the TV station I work for. Weve had issues in the past with lightning getting into the building (from the digital billboard or the 350ft tower outside). Unfortunately the computer went out for the digital billboard and when the repair man from the company that supplies/supports the digital billboard replaced the computer... he unintentionally broke the fiber line... like completely ripped one of the fiber lines from the connector. I ran cat5 to the billboard as a temporary patch to keep it up, as it generates roughly $1000-1500 in ad revenue every day. I had issues initially but had to tweak some settings on the cradle point modem/router to get it working. Once I was able to get the fiber line re-terminated I connected our TP-Link boxes (fiber to cat5 converter) but they wouldnt connect. I could unplug the cat5 cable from the cradle point modem/router and plug it into my laptop and it would connect over the fiber line without any issues... it just wouldnt communicate when connected to the cradle point modem/router. I checked the very few settings on the TP-Link boxes but got nothing. I believe a firmware update on the cradle point modem/router is what killed it (made it no longer work with the TP-Link fiber converters). I ordered a couple of these Gigabit fiber to cat5 converters on a hunch and they worked immediately.... no fuss or config changes needed. They just worked... After 6 weeks of back and forth between getting the computer replaced, running a temp cat5 line and getting the fiber re-terminated I was finally able to put this issue to bed. Shipping was very fast which is why I decided to order from my personal account w/prime (as anything I order through Amazon through procurement at work takes weeks). Got these in a couple days and got reimbursed for the out of pocket expenses. They just worked!!! and thats all that matters....

It works. But if you buy it for improved sound in your stereo system because you can remove copper ethernet, your mileage may vary. My system sounded worse and it’s supposed to do the opposite. If you already have a decent system with high-quality ethernet cables you may introduce noise with these converters. If you’re only using it for computer data connectivity, it’s an A+ best buy.

would recommend.

Its ok

We have 4 of these installed, working great.

Inexpensive and functional

Not much else I can say but that it works great. I have an array of these going to an aggregate switch in my network and so far so good.

Using these devices to extend POE security cameras. Less than 3 months of use and the power supply for one of the media converters has failed. Getting a replacement is rediculas. After 3 days of email exchanges, they want me to ship both media converters & pwr supplies back to get replacements. I have explained 3 x that I only need 1 pwr supply. Gave up & found a D-Link switch with the specs and used it with a modification. Good Luck

Used this for Cat6 to Fiber
