True or false: A single fiber strand can support full-duplex communication.

Explanation:
Full-duplex means sending and receiving at the same time. A single fiber strand can support this by separating the two directions, typically using different wavelengths for each direction (one wavelength for upstream, another for downstream) or by bidirectional transceivers with a circulator. This arrangement lets signals travel in both directions simultaneously without interfering, so simultaneous two-way communication is possible on one fiber. Therefore, the statement is true.
