SONET/SDH TRANSMITTER & RECEIVER

NOTE6: Data and Clock relationship

NOTE7: Signal Detect Response time: Decreasing Light Input / Increasing Light Input

NOTE8: Photo current monitor method

The photocurrent will be calculated based on the voltage drop across on external resistor connected between the

monitoring pin and +5V.
