Abstract: An optical amplifier with improved transient performance has two amplifier stages and a dispersion compensating fiber inserted between the amplifier stages. A control unit generates a pump control signal for a common pump source pumping both amplifier stages via a power splitter. The pump control signal has a feedforward component with a delayed reaction. A feedforward delay time is adjusted to minimize gain variations resulting from input power drops. In a preferred embodiment, the splitting ratio of the power splitter is adjustable to achieve, for instance, either optimum steady-state performance or optimum transient performance.

Abstract: Bidirectional data signals are exchanged between a central unit and a plurality of network terminals. The optical carrier frequencies of the downstream and upstream signals are chosen so that reflections do not interfere with the selected signal at the optical network unit and not with the received upstream signals at the central unit. The optical network units select their associated downstream signal and generate an associated upstream signal.

Abstract: Disclosed herein is a transponder comprising a transmitter and a receiver. The transponder further comprises a receiver input amplifier, a bypass line, and a control unit configured for determining the performance of the transponder in relation to an OSNR related parameter, by controlling the transponder to generate a noise signal to be received by the receiver. The receiver input amplifier is operated to thereby cause ASE in the receiver input amplifier to facilitate the determination. A test signal is generated at the transmitter Said noise signal and said test signal, and/or one or more respective replicas thereof, are superimposed to form a combined signal to be received by said receiver to further facilitate determination of said performance related parameter based on said combined signal, wherein for generating said combined signal, said test signal is fed from the transmitter to the receiver by means of said bypass line.
