Inexpensive and functional

I need a lightning break between the cablemodem and my expensive router. Using this and a fiber switch I had lying around. Works fine.

These units burn down easily. I bought 8 pieces lasted for a month got over heated and died. Replaced it with TPLINK expensive but worth every penny.

These make a tremendous difference in an audio system. Depending on the quality of your system, you will be more than a little impressed. It is probably a bigger bang the better your audio system is and I cant compare to my older more midfi type audio systems but thats my gut. People are deploying very sophisticated and quite expensive alternatives but all I can say is this more than meets the threshold to matter so if you have any interest or doubt; give it a try.

Worked great, one unit quit after year and a half. Bought another along with Amazon extended warranty

This does exactly as expected. I have had them running for almost a year now and had no issues.

Im just using this for a short distance for lightning isolation, no where near the distance it is supposed to be able to support so I cant speak to that, however in my application these converters work well, are painless to set up, and just work.

I have purchased Numerous 10GTek Devices. Mainly SFP Modules for both Single Mode and Multimode Fiber Optic Cable. I have never been disappointed in any of their products.

I purchased a pair of these to run single mode fiber to my barn. 100meters of fiber in plastic conduit with these linking at Full Duplex, I am pleased. I do plan to purchase a spare base and SFP insert in case of lightning damage or some other induced failure.
