II. Pin Descriptions

 Notes:

1.Circuit ground is internally isolated from chassis ground.

2.TFAULT is an open collector/drain output,which is pulled up with a 4.7kΩ–10kΩ resistor on the host board,but is grounded inside the SFP cable plug.

3.Laser output disabled on TDIS>2.0V or open,enabled on TDIS<0.8V.

4.Should be pulled up with 4.7kΩ–10kΩ on host board to a voltage between 2.0V and 3.6V. MOD_ABS pull line low to indicate module is plugged in.

5.LOS is open collector output. Should be pulled up with 4.7kΩ–10kΩ on host board to a   voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

V. ElectricalCharacteristics(TOP=0°Cto70°C,VCC=3.3±5%Volts)

Notes:

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

2.Into 100Ω differential termination.

3. Loss Of Signal is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
