Review: Easy way to extend high speed LAN in the home. Better than WIFI. - Needed to extend the fiber Ethernet connection from the router where in comes in from the service provider. WIFI 100 feet away in the home speed was much slower, like 75% slower.. With this pair of media converters and a single LC-LC fiber cable - 30 meters long does the job. Working bi-directional of a single fiber I get the same data rate as seen at the router, about 950 MBPS up and download with no data speed loss. Awesome technology. The transceivers transmit and receive on different wavelengths so it's full duplex.
Review: Surprising Difference with HT Streaming Setup - 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.

## Questions & Answers

**Q: Can this unit power over ethernet POE? or be used as rs422 serial through ethernet?**
A: Nope.  Psybridge made a product like that.

**Q: Can i use this to convert the fiber to a rj45  for my router?**
A: This converts rj45 to fiber and back again.

**Q: can you manually set to Full Duplex / speed?**
A: No

**Q: Can you recommend a 2 meter fiber patch cable will enable 1000Base transfers?**
A: Through the RJ45 gigabit cable transmission within 80 meters, can achieve gigabit rate;
1.For 2 meters of fiber transmission, the gigabit rate is directly determined by the fiber module and the fiber tran.sceiver. 
2The specification interface of the 2 meters of fiber jumper, FC-SC-LC-ST, is determined by the fiber module.
