Ethernet optical isolation question

[davide256]

buy optical Ethernet  cable solution and you can put "cable wars" to rest for your Ethernet connections, best of all it works for distances you will never approach in your house. Now if only I could change all my interconnects to an optical solution....

i prefer to use optical isolation and i would like to know is there any ethernet opto-isolator?

That's a bit like asking if water can be made wetter... remember that we are talking about the use of optical in its intended mode as a data transmission medium using Ethernet protocols, which works at speeds up to 100gbps today with the right hardware

Hi,  I just bought these

https://www.amazon.co.uk/dp/B01MTUB926/ref=cm_sw_r_cp_awdb_ZGnczbKNM5WVV

and they work very well. I haven't tested for audio quality. They are Chinese made but use quality silicon. Qualcomm chipset in the adapter and ST power components in the smps. They take 5V DC so likely I'll modify another USB cable and power these from official apple chargers as they have been measured elsewhere being very clean. 

 

This model has a bidirectional optic so only needs ans single fibre connection. I couldn't find a 20m single as most are doubles so just bought one and will pull apart.  

tx/rx optic pairs should have a lower bit error rate than a full duplex single optics  solution
