Abstract :
A generic 1.25-Gb/s burst-mode optical transmitter with an intelligent automatic power control has been developed and tested successfully. The chip quickly adjusts the optical power during initialization from safe preset values to the required high and low levels with a guaranteed extinction ratio, and accurately tracks level drifts during data transmission. The measured performance complies with the ITU-T gigabit passive optical network standards including the power leveling mechanism option.
