TX Optical Power High Warning MSB (TXHIGHh)
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
28= 1Ch
Each LSB represents 25.6
W. This register is to be used in conjunction with TXHIGHl to yield a sixteen-bit value. The
values in TXHIGHh:TXHIGHl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXHIGHh is compared against TXOPh. Warning bit Wx is set if TXOPh > TXHIGHh.
TX Optical Power High Warning LSB (TXHIGHl)

D[4]
D[3]
D[2]
D[1]
D[0]
read/write
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
29= 1Dh
Each LSB represents 0.1
W. This register is to be used in conjunction with TXHIGHh to yield a sixteen-bit value. The
values in TXHIGHh:TXHIGHl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXHIGHh is compared against TXOPh. Warning bit Wx is set if TXOPh > TXHIGHh. 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 b.
TX Optical Power Low Warning MSB (TLOWh)
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
30 = 1Eh
Each LSB represents 25.6
W. This register is to be used in conjunction with TXLOWl to yield a sixteen-bit value. The
values in TXLOWh:TLOWl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXLOWh is compared against TXOPh. Warning bit Wx is set if TXOPh < TXLOWh.

read/write
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
31 = 1Fh
Each LSB represents 0.1
W. This register is to be used in conjunction with TXLOWh to yield a sixteen-bit value. The
values in TXLOWh:TXLOWl are in an unsigned binary format. The value in this register is uncalibrated. The value in
TXLOWh is compared against TXOPh. Warning bit Wx is set if TXOPh < TXLOWh. 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.
