Conección super estable

I used these for running fiber long distances in a new plant. Jump out to copper into a switch.No issues getting these working. Do not forget; The sender on one of a fiber line will be the receiver on the other end. They do not work well if your jumper cable has a tie block in the center as you will need to break one side and plug them in the other way.

Great product for when in a pinch with these new starlinks going up and your run fiber between network closets

I’m using these to get my internet out to my workshops. Dead easy to install and work as advertised. Will be buying a few more for the other shop.

Easy to use plug-n-play media converters. Worked perfectly in a 1Gb network. Not tested above 1Gb.

I've ordered four sets of these, and in three of them, at least one transceiver was DOA. If you have other transceivers you can swap them in, but if not it's better to just order a few and then return the ones that are defective. It's good value but the fact they don't always work/some are DOA makes it a bit janky

Units work well. Good throughput. Basically plug and play. AC line is very short (~8 inches). Build seems cheap but time will tell how long they last.By the way... it would have served the manufacturer well to have also read the user manual carefully (see picture).

It does what it's supposed to do, no setup issues. We had a switch have fiber uplink problems, used this to diagnose the problem, then fix it while we ordered a replacement switch. Good value.

I have a pretty high-end audio system. And taking a page out of my digital streamer's book which uses a higher quality of these units to convert copper to light, I felt compelled to see what these fairly inexpensive devices were capable of. So I installed one right after my (inexpensive) ethernet switch and another right near my Nvidia ShieldTV Pro (about 6-7' away). Bought a 3m run of optical patch cable and hooked everything up. To my surprise, the video was SHARP. Even a crappy feed from PlutoTV looked near 4k quality. But the biggest difference was in audio. Yes, it's lossy and even 2 channel PCM often but let me tell you, it is 100% improved. The 'chestiness' resonance/distortion when you turn up lossy DD+ on many programs is all but gone. It's clean and just goes louder and louder. Imaging/phasing is what is even more dramatic. In the morning, I like to get up early and have a cup of coffee. I watch PlutoTV and as anyone who frequents that app, they know how often you see the same commercials over and over and over again. The difference for me in the morning is, I only fire up my multi-channel amp which powers my center, surrounds and atmos speakers. My mains amp remains off since it sucks a lot of juice (Ayre Acoustics). I am normally browsing my phone or tablet for news, events or whatever is going on but today I actually was jarred by a simple commercial. The sound is usually crammed almost entirely into the center speaker and some dribble in the L/R surrounds. The on camera scene was in fact front and center. But his wife says something from the other room which normally just flows out from the center channel. Today, her voice was far, far behind me. Not a peep of her voice was in my center speaker and it really caught me off guard since I've heard this commercial soo many times before. She was not only JUST in the surrounds but also out of phase to make her sound like she was back behind me some 15'. It was erie to say the least! Last night with all speakers on, I watched some Dolby Atmos material and it was just as fabulous. My Atmos speakers were really loving the workout from streaming. Placement within the room was approaching that of my Oppo UDP-205 player with Atmos or a DTS:X movie playing.My NAS is almost complete and I'll be ripping my 500-600 blurays/4k movies to it. I can only imagine how lossless audio will benefit!Now for theories about why this made things better, I really don't have one. I am no scientist but when I bought the audio streamer and it took out all the hiss and distortion (usually in the form of loudness, bloat and harshness) from my copper ethernet in my home network, I knew I had to at least try fiber optic on my video streamer. My questions are, how does the fiber clean up a dirty (noisy) signal? It doesn't filter anything out that I'm aware of. Or maybe because fiber works at such a high frequency, could it shunt the RF or EMI out somehow with the conversion process? But then again, that's filtering. So I don't know... I have much to learn about but I know what I see and hear. And I had many, many hours on my equipment prior to adding in fiber optic ethernet. The difference is simply unmistakable. And there is nothing on this concept (using it in HT applications) on the internet that I could find. I say give it a try. If you don't see or hear a difference, simply return the items and move on.
