Notes

1. Connected directly to TX data input pins. AC coupling from pins into laser driver IC.

2. Or open circuit.

3. Into 100 ohms differential termination.

4. Unfiltered, 20 – 80 %

5. LOS is an open collector output. Should be pulled up with 4.7k – 10kohms on the host board. Normal

operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5V.

6. Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to

specified value applied through the recommended power supply filtering network.

7. If measured with TJ-free data input signal. In actual application, output TJ will be given by:
