Different wavelengths for the forward and reverse ¡°lasers¡± (or LEDs).

Pretty common approach (DM8G Fiber uses the same concept; not sure if they¡¯re optically compatible) but also very common in IT/Telecom particularly over long distances [or when you¡¯re leasing fiber by the strand]. IIRC, there are options on the market that let you stack 5 or more full duplex 10Gb* links on a single strand by multiplexing a 10 wavelengths [5 forward, 5 reverse].

*- Last I looked which was a while ago. Seeing as Cisco now has 40Gb options in 1RU access/edge switches it wouldn¡¯t at all surprise me if this has moved up¡
