9.6.2LED driver signals

Fault and Active LED signals are located in the FC-SCA connector (J1). See Table 29 for the output character- istics of the LED drive signals.

Table 29: LED drive signal

State	Current drive available	Output voltage

LED off, high	0 < IOH < 100µA

LED on, low	IOL < -30 mA	0 < VOL < 0.8V

9.6.3FC Differential output

The serial output signal voltage characteristics are provided in Table 30. The outputs are not AC coupled in order to deliver maximum signal without rise and fall time degradation. You must AC couple the receiver to iso- late potentially different DC characteristics of the outputs and the receiver.
