Abstract:
1. A digital optical receiving module to monitor a signal quality of a transmitted and modulated optical signal, the digital optical receiving module comprising: an optical input; a first digital electrical output; an optoelectronic transducer device configured to convert a modulated optical signal to an analog electrical signal; a decision-making device electrically connected to the transducer device, the decision-making device configured to convert the analog electrical signal to a digital signal and to pass the digital signal to the first digital electrical output; a quality recording device electrically connected to the transducer device, the quality recording device configured to determine a quality of the analog electrical signal before it is converted to the digital signal by the decision-making device and to produce an information signal as a function of the quality of the analog electrical signal; and a signal improvement device electrically connected between the transducer device and the decision-making device, the signal improvement device configured to improve the quality of the analog electrical signal when the quality of the analog electrical signal indicated by the information signal is below a threshold and to be turned off when the quality of the analog electrical signal indicated by the information signal is above the threshold.
