ipolexGigabit Single-Mode LC Fiber to Ethernet Media Converter (SFP LX Modules Included),1.25G Fiber Media Converter, 1000Base-LX to 10/100/1000Base-TX, 1310nm, SMF, Transmission up to 20KM, 2 Pack

As it looks like the reviews Amazon associates with this device are with 'similar' devices, thought I should chime in on how this particular device works.I plugged in a 'Cisco' rated 10GTek multimode, 550m range SFP transceiver into this, plugged the other identical SFP transceiver into my genuine Cisco SG300 series switch and strung up a 30m pre-made multi-mode fiber rated for outdoor use. The goal of this setup over copper is electrical isolation in case of lightning. It just works. At this it is by far the cheapest solution I have hit so far that just works.I tested performance between my laptop and main computer with iperf and performance was identical between directly plugging in laptop to my Cisco SG300 and through this media converter, near 1Gb/s speeds.With it being so quick, cheap, and easy to do fiber this way, one has to wonder why the fastest ISP I can get in the middle of a major, dense city only provides much crappier, unreliable, fails as soon as the power goes out, and slower service with much more expensive hardware so they can do it over coax and my only other option is antique, slow phone lines. Plus when I moved in they had to string up new lines and of course they chose copper, not fiber, which makes no sense to me. With a cheap single mode SFP transceiver and a cheap media converter they could provide me much faster service with lines running back to their central office where they could have UPSes and backup generators to make the service reliable and sell the service for more money because it would be worth it. At this the stuff wouldn't be going out / getting fried every time there was a lightning storm, which has become increasingly common and intense in recent years where I live. Also FiOS makes no sense to me either when I was in a FiOS neighborhood because they installed this gigantic box (ONT) in my closet that must of cost them a fortune while this cheap little box I am using does the same job except much faster at maybe 1/40th the price. So it's like I could provide awesome service that serves the customers' every need and do it well with a $25 box or I could do it badly with a $1,000 box. Of course telco logic is do it badly with the super expensive box that falls way short of the mark every time.

We have a digital billboard outside the TV station I work for. We've 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 wouldn't 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 wouldn't 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 that's all that matters....

I used this gigabit media converter to convert Single Mode Fiber for an internet circuit connected to an out-of-band management device that didn’t have an SFP port. The device worked perfectly without any issues. Just a heads-up—if you’re installing this in a data center, make sure to order a C14 to NEMA adapter for the power supply if your PDUs use that type of plug. Solid product and did exactly what I needed!

This was plug and play with no issues. Just a straight forward solution at the right price.

Just install a Fiber run from the house to my backyard office between my Unifi Switches (USW24 to Flex Mini) and needed to convert the Fiber run on the Mini-side to a copper RJ45 (8P8C) port. Works incredibly well, without getting errors!

Excellent quality, good performance.

I just want to confirm that this converter delivers at least 900Mbps up an down for Bell Fibe 1G in Ontario. It it very-very similar to the original Home Hub 3000 (I didn't run many tests so I assume there is no noticeable degradation in performance). I don't see why I can't go up to full 1G if you connection allows it.The long story:I've just ordered Bell Fibe 1G. I explicitly asked sales person if Bell could give me HH3000 (with proper removable SFP transceiver) instead of HH4000. The included SFP was "Nokia ONT SFP g-010s-a".I have Ubiquity Edge Router Lite. It was configured to work with Rogers modem in bridge mode, so the router used DHCP on eth0 port which is WAN port. I had to reconfigure it in the following way:1. On the main Dashboad screen eth0 interface -> Actions -> Config -> Set address to "No Address"2. On the main Dashboad screen Add Interface -> VLAN {VLANID:35, Interface:eth0, No Address, MTU:1500}3. On the main Dashboad screen Add Interface -> PPPoE {Interface:eth0.35 (the VLAN you just created), No Address, MTU:1492}4. Go to Port forwarding/NAT/Firewall/DNS tabs and change everything that points or uses eth0 from eth0 to pppoe0.Now you internet should start working but unreliably. Some sites/pages will open, but with many errors.Open EdgeRouter CLI and run the following command:"set firewall options mss-clamp interface-type pppoe""commit""save"This should fix MTU issues and internet should start working properly, but not at full speed if you have offloading disabled.Enable offloading by running the following commands (or by going to: "Config Tree > System > Offload > IP4 - Settings for IPv4 hardware offload" and set "enable" value ):"set system offload ipv4 pppoe enable""set system offload ipv4 vlan enable"You can also enable offloading for the following, but it's not that important:"set system offload ipv6""set system offload ipv4 disable-flow-flushing-upon-fib-changes""set system offload ipv4 bonding enable""set system offload ipv4 forwarding enable""set system offload ipv4 gre enable"Finally run:"commit""save"You should have speed close to 1G up and down.

good

The Adapter functions as desired though only contained a US power adapter so converters or an additional power adapter is required if you’re from outside the US
