CQENPR A Pair of Ethernet PoE Media Converter, Single Mode SC Single Core, Fiber PoE Converter, 10/100Mbps, Transmission Distance 20KM, IEEE802.3u, Plug and Play (1000Mbps)

I needed to move my PoE camera away from the router and converter made it possible. Works great and you dont need to worry about running Ethernet cable and going beyond the signal reach. Power adapter uses 5.5 connector, you would also need Fiber cable to use the converter (not included in the set).

These are hi-tech and marvellously robust as well as compact for all the features they have. A specialised product but if you need these theyre great as they do all one needs from them. A great product. :)

I had some trouble figuring it out, only because I basically know nothing about optical fiber networking, the ins or outs. But I figured it out. I am reading my speeds at 1000mps. Very happy:)

This review seems to apply to both the T-Base 1000, as well as the T-Base 10/100 model, as I wrote a review of that one previously and when I opened this one to review it the other review populated the form. So, I will edit it to cover both models, The comments concerning the CQENPR Ethernet PoE Media Converters included in this pair being in nice looking very durable metal cases applies to both, as the cases are identical. If they are used with PoE on each end they are extremely compact. They are also very light weight. So, they can unobtrusively be installed almost anywhere. The status lights are utilitarian and provide the needed information. These now have both been tested with a full 100-meter cable. I did not use PoE, but external 12V DC power cubes for this test. They can accept up to 48V. They perform flawlessly and to specification. My suspicion is they will run cooler with the lower voltage. But I have not confirmed this. As the circuitry and laser are physically in this unit the voltage must likely be stepped down from 48V internally to drive the circuitry, which would produce more heat. If driving via PoE and the converter is a significant distance away from the PoE injector more voltage will be warranted to assure at least something approaching 12 volts reaches the converter. My intended application is actually to use these along with a 100-meter fiber cable to electrically isolate a computer from remote sensors and control circuits in an area which is susceptible to frequent lightning strikes. I do not need a high-speed connection there as minimal data will be passed. I was initially going to use the 10/100 model. But now, as it will give me extra overhead I will upgrade to the T-Base1000 model. Running a standard ethernet cable this long requires much more complexity. Also, because we are on top of a mountain, but also generally speaking, making a copper connection between the two locations will create a surge and electrical grounding problem. You do not need a direct lightning strike to create serious problems. Nearby lightning strikes, sometimes even over a mile away, can give rise to in-rush situations and very significant potential differences between two widely separated locations. This can easily damage sensitive computer switching equipment, and even the computers themselves. In short, if using copper, no matter how I do it I will run a risk of having component damage. Overall, these units do what they are supposed to do over the tested distance. The T-1000 model is the better value as compared with competing manufacturers similar units. The T-10/100 is a little pricy for the feature set. Both are quite compact, which can be an added bonus in many cases. Collectively, I can easily award five stars. If you need a compact PoE, or powered, single mode media converter either model can be a good choice.
