ROHS-COMPLIANT 2.125, 1.25 AND 1.063 GBPS 850 NM TRANSCEIVER
Transceiver Temperature in degrees Celsius: Internally measured. Represented
as a 16 bit signed two’s complement value in increments of 1/256 degrees Celsius
from -40 to +125 degree C with LSB equal to 1/256 degrees C. Accuracy is ± 3 de-
grees Celsius 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 100V 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
dened as the full 16 bit value(0-65535) with LSB equal to 2A with a measure-
ment range of 0 - 131mA. Accuracy is ± 10% of nominal value over the specied
operating temperature and voltage ranges.
TX Output Power in mW: Represented as a 16 bit unsigned integer with the power
dened as the full 16 bit value (0-65535) with LSB equal to 0.1W. Accuracy is ±
2dB over the specied temperature and voltage ranges over the range of 100W to
800W (-10dBm to -1dBm). 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 0.1W. Accuracy over the specied temperature and voltage ranges is ±
3dB from 30W to 1000W (-15dBm to 0dBm).
Reading the data
The information is accessed through the MOD_DEF(1), and MOD_DEF(2) con-
nector 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 3, Table 4, and Table 5 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.
The EEPROM WP pin is internally tied to ground with no external access, allowing
write access to the customer-writable eld(bytes 128-247 of address 1010001X).
Note: address bytes 0-127 are not write protected and may cause diagnostic mal-
functions if written over.
