RX Optical Power High Alarm Threshold MSB (RXMAXh)
D[7]
D[6]
D[5]
D[4]
D[3]
D[2]
D[1]
D[0]
read/write
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
32 = 20h
Each LSB represents 25.6
W. This register is to be used in conjunction with RXMAXl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in RXMAXh is compared against RXOPh. Alarm bit Ax is set if RXOPh
> RXMAXh.
RX Optical Power High Alarm Threshold LSB (RXMAXl)

D[2]
D[1]
D[0]
read/write
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
33 = 21h
Each LSB represents 0.1
W. This register is to be used in conjunction with RXMAXh to yield a sixteen-bit value. The
values in RXMAXh:RXMAXl are in an unsigned binary format. The value in this register is uncalibrated. The value in
RXMAXh is compared against RXOPh. Alarm bit Ax is set if RXOPh > RXMAXh. Since RXOPl is always zero, it is
recommended that this register always be programmed to zero. This register is provided for compliance with SFF-
8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or warning bits.
RX Optical Power Low Alarm Threshold MSB (RMINh)
D[7]
D[6]
D[5]
D[4]
D[3]
D[2]
D[1]
D[0]
read/write
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
34 = 22h
Each LSB represents 25.6
W. This register is to be used in conjunction with RXMINl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in RXMINh is compared against RXOPh. Alarm bit Ax is set if RXOPh <
RXMINh.

read/write
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
35 = 23h
Each LSB represents 0.1
W. This register is to be used in conjunction with RXMINh to yield a sixteen-bit value. The
values in RXMINh:RXMINl are in an unsigned binary format. The value in this register is uncalibrated. The value in
RXMINh is compared against RXOPh. Alarm bit Ax is set if RXOPh < RXMINh. Since RXOPl is always zero, it is
recommended that this register always be programmed to zero. This register is provided for compliance with SFF-
8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or warning bits.
