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)

We are using NDI PTZ cameras for a studio set-up that use POE. These converters worked well to extend the range in for a longer run and provide additional options instead of a full managed switch .

Bought these to extend Ethernet to another building but it wasnt exactly what I was looking for. These media converters use a single strand of fiber rather than the typical pair, so TX and RX are combined over that single strand. In the end I picked up a pair of Cisco switches that had 10G LR SFP modules with the LC connectors Im used to and am using them instead. Not knocking these CQENPR converters, they work but they just werent what I was looking for.

I have only tested these on the bench, but they seem to work just fine. I was concerned from other reviews that I may have only gotten a 10/100MHZ unit, but these are 10/100/1000MB units. I do want to test them in the field and check the range and actual throughput. I connected them to a regular 802.3af/802.3AT POE switch and after a quick boot up they worked just fine. Really handy idea, it saves having to use a regular media converter with SFP, another power adaper and etc. They really are just plug and play. Great Idea, and really nice product. I will update this review if my field testing turns up any problems.

This converter arrives in a very nondescript package but works well. I was able to extend some POE devices all the way back to my PoE switch 10 floors down the building. Nothing really to it! Plug them in on a functioning fiber path and youll be good to go. Im writing this review with them in use for less than 24 hours. Ill circle back if anything changes but, so far, so good!

They are small, unobtrusive, and they provide plenty of power. I needed it for an access point that I put in my house and love it. Much easer than trying to deal with either external power, or the expense of a POE switch. . . Will work with security cameras too as long as they support POE (which a lot of home consumer cameras dont, so make sure yours does befor you go buying the wrong stuff). Great little device!

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.

I just installed my first POE security camera. I got these over a potential concern of the distance I might need to run between the camera and router. These units allow you to substitute Ethernet cable with optical fiber, which handles greater distances and at faster speeds. The initial installation was using Ethernet and the overall quality was acceptable. Then I switched the setup utilizing these converters and optical fiber, anticipating an improvement. Unfortunately... I did not notice any. In all fairness, that could be due to the camera. Now, that being said, I suspect it was due to my not encountering the great distance I anticipated when installing the camera. In other words... I dont think I really needed these converters after all. Still, my installing them did show how simple they are to use and they didnt hurt anything. There are other POE cameras I plan to install, a few of which will for sure require long runs. Having already used these converters without a hitch, I will certainly try them again.

I am using this to optically isolate the ethernet connection between two buildings. This device works with PoE or power supply which provides great flexibility.

Good quality, full speeds, very useful. Ive been meaning to run a 150 ethernet cable out to the garage- yet, I didnt want to run a POE cable to a cam out there. The longer the cable, the more strain on the switch, and switches arent cheap. With these adapters used as a pair, all that cable length is replaced by a simple fiber optic cable. Much easier to run through the house and tight places. So, attach ethernet adapter in house. Attach SC single mode cable to adapter one, and run the 150 to the second adapter in garage. There were several ways to power this; either with POE in the house, and a special POE injector at the far end, -OR - forget the POE altogether, and use a 12 volt adapter on each end plugged into the adapter. I have a POE switch, but liked the idea of using simple 12 volt adapters on either end. In the photos, you can see the adapters I used (easy to get pretty much anywhere) that I dug out of my old parts box. Youll see the converters ethernet light up with either the Blue POE wire in one picture, or with unpowered ethernet (a black connector) and a 12 v/2 amp power supply plugged into the converter. Works the same way on both ends. Run the SC single mode optical cable from converter A to B (it doesnt matter which order you put them in) and youre done. This is a simple, elegant solution that saves strain by eliminating LONG POE cable runs. To boot, you can make that optical cable, literally, miles long. In my mind, this is the right stuff!

These are really basic fiber to ethernet convertor/transceivers. They are PoE, however, if you do not have a PoE switch, you can pick up a couple of 12v 3a dc power adapters and inject power that way. I was able to get a pretty long long run with these and throughput was decent, however since its single mode and single channel bidirectional traffic will be impacted due to this. I did notice significant latency, however based on the simplicity & the purpose of the setup its completely acceptable. I dont see this as a detractor in the least. I however wish these were the 1GBE version to maximize the potential bandwidth available to the source & target. But they still function as prescribed so I wont be taking any points away for this. If you need a good solution like this, pick up a pair of these, a couple of power adapters as described, and a SC/APC to SC/APC cable in whatever length you need.
