英文摘要	A system suitable for burst communication comprising selection circuitry 610 which during a transmission period selects a data input value and during an extension period after the transmission period selects either a logical high or a logical low value, drive circuitry applies current to a laser value so that the diode 101 provides an optical output, the current corresponds to the value selected by the selection circuitry, an optical sensor module 102 providing an output corresponding to the observed optical output and the logical high or logical low values and a controller 607 receiving desired minimum and maximum optical outputs and receiving the output from the optical sensor module and comparing this information to provide control output values to the drive circuitry. The modulation index of the optical output of the laser diode may be controlled. The optical sensor may be a photodiode. A trans-impedance amplifier may provide the sensor module output.
