Notes:

3. Laser output disabled on TDIS > 2.0V or open, enabled on TDIS < 0.8V .
4. Should be pulled up with 4.7k -10k on host board to a voltage between 2.0V and 3.6V. MOD ABS pulls line low to indicate module is plugged in.
5. LOS is open collector output. Should be pulled up with 4.7k - 10k on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
