Question about TP-Link Tl-Sm321b

Yes, a tutorial from 02/2021 (in German) shows the procedure for fibre with an EdgeRouter: https://www.mybetacube.de/forum...

Hello,

For this to work, the FO must be single mode and the Transceiver on the other side must be an A model (TL-SM321A) as these transceiver models operate bi-directionally on a single FO.

I don't think so, even though I don't have that material.
