摘要： An optical fiber amplifier has a length of active optical fiber into which pump light from a pump laser is injected. The pump laser is locally controlled by a laser monitor diode, the pump laser and the laser monitor forming a pump laser module. The overall amplification of the amplifier is controlled by two control loops: a feed forward loop and a feed back loop. These two control loops also control the pump laser. The feed forward loop gives a fast response and receives an input signal from an input monitoring diode. The feed back loop gives a slower response and sets the overall gain of the amplifier. The feed back loop receives an input signal from an output monitoring diode. In the feed forward loop, the input power level is biased and controlled by a set offset values from sources to provide a signal corresponding to a pump power reference level which maintains the desired gain. The offsets of characteristic curves indicating an overall behavior of the optical amplifier. The pump power reference level is further modified in accordance with the pump monitor signal locally controlling the pump laser. This gives a very fast and accurate control in spite of the non-linear behavior of the optical fiber amplifier.

摘要： A sampling unit (110) receives an input clock signal (CLKin) having a varying period time, and samples the input clock signal (CLKin) based on a sampling clock signal (CLKsmpl) that has a frequency being substantially higher than an average frequency of the input clock signal (CLKin). The sampling unit (110) produces a respective period length value (PL) for each period of the input clock signal (CLKin). An averaging unit (120) receives a number of period length values (PL) from the sampling unit (110), and based thereon produces an average period length value (PLavg) representing an average period time for the input clock signal (CLKin) over an averaging interval including a number of periods equivalent to said number of period length values (PL). An output unit (151) produces a stabilized output clock signal (CLKout) based on the average period length value (PLavg) and the sampling clock signal (CLKsmpl).

摘要： The phase difference of two periodic input signals having essentially the same frequency are measured in, for example, a communication system, in an accurate way with a high resolution and utilizing digital components. A high resolution digital phase detector which can be included in a phase locked loop comprises an oscillator providing a clock signal having a high frequency that is not an integer multiple of the frequency of the input signals. The clock signal is provided to a clock signal input of a counter, and the periodic signals are fed to the start and stop terminals of the counter. Output terminals of the counter are directly connected to inputs of a digital low-pass filter in which an average value calculation is carried out of the integer values of the output of the counter. Because of the small frequency deviation from the integer multiple value, a slow sliding of the oscillator phase compared to the phase of the input signals is achieved, such that all possible integer values on the output of the counter are run through. A very accurate calculation of the phase position is achieved by the average value calculation of these integer values in the low-pass filter. In a complete phase-locked loop, a voltage controlled oscillator provides one of the input signals to the counter through a divider circuit.

摘要： In a data transmission system, a first node receives at least two sets of input data signals including at least two signals being based on different synchronization sources. The first node extracts a respective clock signal representing the embedded clock signals from the sources, samples and formats these signals for transmission according to a TDM structure. The TDM formatted signals are transmitted as at least one bit stream over a transmission medium to at least one second node, where the bit stream is demultiplexed into at least two sets of output data signals respective demultiplexed clock signals representing the sampled clock signals. A jitter attenuating mechanism reduces an amount of frequency jitter to below a predefined level to produce a respective clock signal having a synchronization quality superior to that of the demultiplexed clock signals. An interface module recombines each data signal with its associated clock signal.
