Abstract:
In some embodiments, an apparatus includes an optical transceiver having a photo diode and a processor configured to be operatively coupled to the photo diode. The photo diode is configured to measure a set of receiver optical power (ROP) values at a set of baud rate values. The processor is configured to measure a set of bit error rate (BER) values of a digital modulated signal at the set of baud rate values. The processor is configured to determine an estimated optical signal noise ratio (OSNR) value at a baud rate value from the set of baud rate values based on the set of ROP values and the set of BER values. The processor is configured to send a signal indicating the estimated OSNR value at the baud rate value such that a planned route is selected to send data signals based on the estimated OSNR value.
