> We ended up using a circulator, and used a single fiber for full-duplex without issues. Great hack. BTW, I always want to see if a circulator can be used as a Wi-Fi booster. A typical Wi-Fi chipset has a noise figure around 6 dB, in principle, if a high-performance LNA is used, connected via a circulator (so the Wi-Fi doesn't transmit into the amplifier), 3 or 5 dB improvement for RX should be possible (and without violating any radio regulation!). But I don't have to tolerate the horrible campus network since then, I don't have any motivation to try it anymore... > Take home message, if you have enough SNR (the media converter bridges are designed for 15 km) you can get away with all sorts of hacks. It's said that all communication accomplishments are ultimately a problem of adding a bunch of positive and negative numbers in your link budget. ;-)
