Abstract
The present invention provides apparatuses and methods for measurement and control of a laser in a passive optical network. In particular, prior to receiving a transmission grant, the laser is pre-driven at a current below a predetermined threshold to “pre-charge” the laser. Also, during the zero level measurement interval, the laser is driven at a non-zero level and the required zero level current is calculated.
