Notes:
9. Time from rising edge of Tx Disable to when the optical output falls below 10% of nominal.
10. Time from falling edge of Tx Disable to when the modulated optical output rises above 90% of nominal.
11. From power on or negation of Tx Fault using Tx Disable.
12. Time from fault to Tx fault on.
13. Time Tx Disable must be held high to reset Tx_fault.
14. Time from LOS state to Rx LOS assert.
15. Time from non-LOS state to RX LOS deassert.

Note:
In order to meet the link power budget the transmitter can trade off OMA, spectral width and center wavelength as shown in Figure 3.
