Abstract

An optical network unit (ONU) for optical transmission in a burst mode includes an electro-absorption modulated laser (EML) transmitter including a laser diode (LD) and configured to transmit an uplink optical signal through the LD, an electro-absorption modulator (EAM) driver integrated circuit (IC) (EAM driver IC) configured to amplify an uplink data signal and provide the amplified data signal to the EML transmitter, an LD burst-mode driving circuit configured to control an operation of turning on or off the LD based on a burst-enable signal, and a media access control (MAC) configured to transmit the data signal to the EAM driver IC and transmit the burst-enable signal to the LD burst-mode driving circuit.
