Abstract
In an optical network unit, an optical-intensity monitor monitors the received optical intensity of a received light beam input thereto, and a controller uses the received optical intensity to produce an intensity control signal, in response to which a semiconductor optical amplifier selectively amplifies or attenuates the optical intensity of the received light to produce an intensity-adjusted light beam, which a receiver can receive within its receivable-intensity range.
