TX Optical Power High Alarm MSB (TXMAXh)
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
24 = 18h
Each LSB represents 25.6
W. This register is to be used in conjunction with TXOPl to yield a sixteen-bit value. The
values in TXOPh:TXOPl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXMAXh is compared against TXOPh. Alarm bit Ax is set if TXOPh > TXMAXh.
TX Optical Power High Alarm LSB (TXMAXl)
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
25 = 19h
Each LSB represents 0.1
W. This register is to be used in conjunction with TXMAXh to yield a sixteen-bit value. The
values in TXOPh:TXOPl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXMAXh is compared against TXOPh. Alarm bit Ax is set if TXOPh > TXMAXh. Since TXOPl 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.
TX Optical Power Low Alarm MSB (TXMINh)
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
26 = 1Ah
Each LSB represents 25.6
W. This register is to be used in conjunction with TXMINl to yield a sixteen-bit value. The
values in TXMINh:TMINl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXMINh is compared against TXOPh. Alarm bit Ax is set if TXOPh < TXMINh.
TX Optical Power Low Alarm LSB (TXMINl)
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
27 = 1Bh
Each LSB represents 0.1
W. This register is to be used in conjunction with TXMINh to yield a sixteen-bit value. The
values in TXOPh:TXOPl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXMINh is compared against TXOPh. Alarm bit Ax is set if TXOPh < TXMINh. Since TXOPl is always zero, it is
