ROHS-COMPLIANT 4.25 GBPS 850 NM ESFP TRANSCEIVERS;
EXTENDED/INDUSTRIAL TEMPERATURE & VOLTAGE
Transceiver Temperature in degrees Celsius: Internally measured. Represented
as a 16 bit signed two’s complement value in increments of 1/256°C from -40 to
+125°C with LSB equal to 1/256°C. Accuracy is ± 3°C over the specied operating
temperature and voltage range.
Vcc/Supply Voltage in Volts: Internally measured. Represented as a 16 bit un-
signed integer with the voltage dened as the full 16-bit value (0-65535) with LSB
equal to 100 V with a measurement range of 0 to +6.55V. Accuracy is ± 3% of
nominal value over the specied operating temperature and voltage ranges.
TX Bias Current in A: Represented as a 16 bit unsigned integer with current de-
ned as the full 16 bit value(0-65535) with LSB equal to 2 A with a measurement
range of 0 - 131 mA. Accuracy is ± 0.5 mA over the specied operating tempera-
ture and voltage ranges.
TX Output Power in mW: Represented as a 16-bit unsigned integer with the pow-
er dened as the full 16-bit value (0-65535) with LSB equal to 0.1 W. Accuracy is
± 2 dB over the specied temperature and voltage ranges over the permitted range
of 100 W to 800 W (-10 dBm to -1 dBm). Data is not valid when transmitter
is disabled.
RX Received Optical Power in mW: Represented as average power as a 16-bit un-
signed integer with the power dened as the full 16-bit value (0-65535) with LSB
equal to 0.1 W. Accuracy is ± 3 dB over the specied temperature and voltage
ranges over the power range of 30 W to 1000 W (-15 dBm to 0 dBm).
Reading the data
The information is accessed through the MOD_DEF(1), and MOD_DEF(2)
connector pins of the module. The specication for this EEPROM (ATMEL AT-
24CO1A family) contains all the timing and addressing information required for
accessing the data.
The device address used to read the Serial ID data is 1010000X(A0h) and the ad-
dress to read the diagnostic data is 1010001X(A2h). Any other device addresses
will be ignored. Refer to Table 4, Table 5, and Table 6 for information regarding
addresses and data eld descriptions
MOD_DEF(0), pin 6 on the transceiver, is connected to Logic 0 (Ground) on the
transceiver.
MOD_DEF(1), pin 5 on the transceiver, is connected to the SCL pin of the EEPROM.
MOD_DEF(2), pin 4 on the transceiver, is connected to the SDA pin of the EEPROM.
Decoding the data
The information stored in the EEPROM and the digital diagnostic information
including organization is dened in the Small Form-Factor document SFF-8472
draft rev 9.5, dated June 1, 2004.
