Abstract
Proposed is an optical data transmission device for an optical access network that comprises a laser transmission unit, which generates an optical transmission signal, and a driving unit, which controls the laser transmission unit for modulating the transmission signal. The device comprises an optical reception unit that converts the received optical signal into an electrical measurement signal. For this, the reception unit contains a photo-diode and an electrical amplifier. The optical reception unit is separate from the laser transmission unit. A control unit controls the laser transmission unit, such that the optical transmission signal is modulated in dependence on a measurement signal. The control unit measures multiple electrical measurement signals during a measurement interval and determines an averaged received electrical measurement signal. Even furthermore, the control unit controls the electrical amplifier, such that the electrical amplifier is turned off during a time interval prior to the measurement interval.
