Note
1) Tx Fault is an open collector output that shall be pulled up with a 4.7k - 10kΩ resistor on the host board. Pull
up voltage between 2.0V and VccT+0.3V. When high, output indicates a laser fault of some kind. Low
indicates normal operation.
Tx Fault is asserted when bias current of laser exceeds the factory-calibrated threshold level.
2) Tx Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module
with a 4.7kΩ resistor.
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7k - 10kΩ resistor on
the host board. The pull-up voltage shall be VccT.
Mod-Def 0 indicates that the module is present
Mod-Def 1 is the clock line of two wire serial interface for serial ID
Mod-Def 2 is the data line of two wire serial interface for serial ID
4) LOS (Loss of Signal) is an open collector output that shall be pulled up with a 4.7k - 10kΩ resistor. Pull up
voltage between 2.0V and VccR+0.3V. Low indicates normal operation.
5) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should
be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and
is thus not required on the host board.
6) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the
host board.

Warning
Use the product with the rated voltage described in the specification. If the voltage exceeds the maximum rating, overheating or
fire may occur.
Caution
Do not store the product in the area where temperature exceeds the maximum rating, where there is too much moisture or
dampness, where there is acid gas or corrosive gas, or other extreme conditions. Otherwise, failure, overheating or fire may
occur.

Checksum Byte 95 contains the low order 8 bits of the sum at data
address bytes 0-94.
The values are interpreted differently depending upon the option bits set at address 92. If bit 5 "Internally Calibrated" is set, the values are calibrated absolute measurements which are denoted as (Int. Cal.) below. If bit 4
"Externally Calibrated" is set, the values are A/D counts, which are converted into real units per the subsequent
conversion equations denoted as (Ext. Cal.) below. Measured parameters are reported in 16 bit data fields, i.e.,
two concatenated bytes. The Externally Calibrated method is recommended in order to achieve the received
optical power monitoring for as low as the minimum sensitivity level.
Transceiver temperature: Temperature, T, is given by
T = TAD (Int.Cal.)
T = TSLOPE * TAD + T OFFSET (Ext.Cal.)
Where TAD is 16-bit signed 2's complement A/D value at bytes 96-97, T SLOPE is unsigned fixed-point value at
bytes 84-85 and TOFFSET is signed 2's complement value with LSB equal to 1/256 deg-C at bytes 86-87. The
result, T, is 16-bit signed 2's complement value with LSB equal to 1/256 deg-C.The monitored output is the
junction temperature of the diode inside the transceiver, hence, there is some discrepancy between the output
and transceiver case temperature of the point illustrated in section 3 mechanical dimension.

Supply voltage: Voltage, V, is given by
V = VAD (Int.Cal.)
V = VSLOPE * VAD + VOFFSET (Ext.Cal.)
Where VAD is 16-bit unsigned A/D value at bytes 98-99, VSLOPE is unsigned fixed-point value at bytes 88-89 and
VOFFSET is signed 2's complement value with LSB equal to 100 µV at bytes 90-91. The result, V, is 16-bit unsigned value with LSB equal to 100 µV.
Laser bias current: Current, I, is given by
I = IAD (Int.Cal.)
I = ISLOPE * IAD + I OFFSET (Ext.Cal.)
Where IAD is 16-bit unsigned A/D value at bytes 100-101, ISLOPE is unsigned fixed-point value at bytes 76-77 and
IOFFSET is signed 2's complement value with LSB equal to 2 µA at bytes 78-79. The result, I, is 16-bit unsigned
value with LSB equal to 2 µA.
Laser output power: Power, TP, is given by
TP = TPAD (Int.Cal.)
TP = TPSLOPE * TPAD + TPOFFSET (Ext.Cal.)
Where TPAD is 16-bit unsigned A/D value at bytes 102-103, TPSLOPE is unsigned fixed-point value at bytes 80-81
and TPOFFSET is signed 2's complement value with LSB equal to 0.1 µW atbytes 82-83. The result, TP, is 16-bit
unsigned value with LSB equal to 0.1 µW.
Received power: Power, RP, is given by
RP = RPAD (Int.Cal.)
RP = RP4 * RPAD4 + RP 3 * RPAD3+ RP2 * RPAD 2 + RP1 * RPAD + RP0 (Ext.Cal.)
Where RPAD is 16-bit unsigned A/D value at bytes 104-105 and RP4, RP3, RP2, RP1 and RP0 are single precision
floating-point values at bytes 56-75. The result, RP, is 16-bit unsigned value with LSB equal to 0.1 µW.
