In passive optical networks using a time-division multiple access (TDMA) scheme, signal bursts from different remote transmitters are interleaved towards a common headend receiver in the upstream direction. We describe a receiver concept allowing correct detection of consecutive signal bursts which exhibit high nonuniformity of amplitude and offset. The time constant of the ac-coupled receiver is controlled by the digital circuitry of the headend station. During reception of the synchronization preambles, it is switched to a low value to allow fast settling of the receiver. Additionally, a power-control system with improved dynamic performance, which can also compensate for fluctuations of optical attenuation, is discussed. The structure of the transmitter and the receiver are described, and the results of simulations and experiments are presented.
