We have been using these for several years now and they have never failed us. Great product,arrived on time.

As of the first day of usage this seems to work properly. I’m using this with a 5m patch connector to protect my network from lightening related issues on my outdoor cameras.

We get lightning storms more frequently, so I wanted to change my long runs to reduce possible lightning related damage (living room to the attic to the bedrooms on the other side of the house - 25-30meter runs). These made it easy and work fine over 25m of fiber. Solid metal housing, good diagnostic leds, supplied with little 5v supply.

If you are using these to create an air gap for lightning protection MAKE SURE THE TWO ADAPTERS ARE PHYSICALLY SEPARATED! DO NOT MOUNT THEM AS PICTURED IN THE LISTING!I have a 300' run between my barn and my home. Put two of these at each end of the ethernet cable to isolate the line from lightning surges. Any long ungrounded outdoor cable can act as an antenna and will attract transient voltages (static emp) from nearby lightning storms.Wanting to save space at both ends of the run, I zip-tied the two boxes together. Since they are metal cases, and surge coming down the long ethernet cable simply jumped from one box to the other. It created small tack-weld spots on all four cases where the current jumped. It fried all four adapters, and a metric crap-ton of switches downstream on either side of the bridge. In all, I lost 7 switches and these four adapters.Interestingly, I had another set of adapters downstream of the failed ones, and they did not pass it on because I'd used thick 3M VHB tape between them, and there was no contact between the boxes.Lesson learned. Certainly not the fault of the his manufacture - but rather a rookie mistake.

Muy bueno aún los tengo y estoy usando

These work great. No lag and easy to set up They make a good air gap between a modem and router for electrical events.You can use them for longer distances but that was my use case.

Slow delivery

Exactly as described and very is to install. Basically plug and play. Remember to double check if you need single mode or multi mode equipment and double check what fiber jumper or fiber connections you need or currently have already to not delay your install. I screwed up and forgot to purchase ST to ST adapter.
