Default Value

Serial Address
A6h
Byte Address
7 = 07h
A valid OEM password is required for access to this register. This register is non-volatile and will be maintained through power
and reset cycles. A fault is generated if the bias current is higher than IBFLT value set in this register.

Byte Address
8 = 08h
A valid OEM password is required for access to this register. This register is non-volatile and will be maintained through power
and reset cycles. A fault is generated if the Transmit power is higher than TXFLT value set in this register.

9 = 09h
A valid OEM password is required for access to this register. This register is non-volatile and will be maintained through power
and reset cycles. A fault is generated if the received power is lower than LOSFLT value set in this register.

10 = 0Ah
Saturation faults are suppressed for a time, tFLTTMR, following laser turn-on. This avoids nuisance tripping while the APC loop
starts up. The length of this interval is (FLTTMRx 0.5ms), typical. A value of zero will result in no fault suppression. A valid
OEM password is required for access to this register. This register is non-volatile and will be maintained through power and
reset cycles.
