SC20, 20 km

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.

Works as expected

Got a pair of these t0 isolate my DAC from jitter on a Wi/Fi network by inserting a fiber optic segment. Plug and play no setup needed. Sound quality improved. Reasonably priced.

Use these all the time,,great product.

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.

Had a lightning strike destroy 2 computers, my ISP router and my personal router Lightning traveled through the Broadband connection through the router through the Cat5 connections to destroy 2 computers via Cat5 connectivity. Go figure. This should mitigate this threat from ever happening. I realized that my APC had and RJ-11 connection to protect against a surge like that but that's after the fact. I now have the broadband connection running into my APC. But I was committed in setting this up to see if it works. It does so beautifully. Refer to the diagram it should answer all your questions.

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.

Slow delivery

Transformer Plugs it came with were US, but handle 100-240v, so just needed a plug converter. Cable I used it with was an SC/SC 30m multimode cable if anyone is wondering what will work - there might be others as Im not an expert in this area, but this worked fine and 30m was only about $50 Australian. Make sure you take off the little white plastic bits on the end if you are new to these.

何の問題も無く使えています。 コスパ最高ですね。

I was fed up with bad wifi in my outbuilding so bought 100m of dual fibre and this pair of units. Although the fibre had to take some quite sharp bends in conduit once installed I'm easily getting more than 900mbps both ways reliably so very happy. Of course I stupidly bought fiber with the wrong connectors but some cheap adapters on this site fixed that.

I inserted these 2 units into my network, between the Cisco switch and my audio streamer. This broke the electrical connection and replaced it with a fibre optic one. This has the advantage of not transferring electrical noise from my server. I have powered the last optical receiver in this chain, not with the supplied power adapter, but with a spare 5v 1amp DC lead from my linear power supply. I'm very pleased with the affect on my hifi system.
