Hello

My purpose is to isolate the WiFi antenna from my provider's modem, so that the audio network is isolated from the WiFi antenna.

The solution I'm thinking of is the one shown in the image below:

I am thinking of using either TL-FC311 B-2 and TL-FC311 A-2 or two MC-220L as converters.

Any suggestions on which of the above?

In the first case the cable used is SC/UPC 9/125 μm single-mode fiber at both ends but it is difficult to find in the market. Most have cables marked SC/SC and I don't know if they are compatible.

In the second case I don't know which SFP Modules I should use. The distances will be very short, 1 to 2 meters between the two converters.

Any help welcome.
