Monitor Data Table 1
Internal Calibration
This transceiver contains internally calibrated values such that the values should be interpreted as follows:
Temperature: The temperature data is the internal transceiver temperature. The temperature is represented
as a 16-bit signed twos complement value in increments of 1/256 °C. This yields a value from -128 to +128 °C
but is only valid if within the operating specifications of the transceiver. Temperature accuracy is +/- 3 °C.
Voltage: The voltage data will be calibrated to the internally measured Transmit V
represented as a 16-bit unsigned integer with the voltage equal to the full 16-bit decimal value (0 to
65535)*100 μV. This yields a total range of 0 to 6.55 volts but is only valid if within the operating specifications
of the transceiver. Accuracy is +/-3% of nominal voltage (3.3 +/- 0.10 V)
TX Bias: The TX Bias data is calibrated to reflect the average current biasing the laser diode. The TX Bias is
represented as a 16-bit unsigned integer with the current value equal to the full 16-bit decimal value (0 to
65535)*2 μA. This yields a total range of 0 to 131mA but is only valid if within the operating specifications of
the transceiver. Accuracy is +/-10% of nominal value over specified operating temperature and voltage.
TX Power: The TX Power data is calibrated to reflect the average power coupled into a nominal fiber [7]. The
accuracy takes into account the fiber to fiber variation and also calibration test equipment accuracies. The TX
Power is represented as a 16-bit unsigned integer with the power value equal to the full 16-bit decimal value
(0 to 65535)*0.1 μW. This yields a total range of 0 to 6.55 mW but is only valid if within the operating specifi-
cations of the transceiver. Data is not valid when the transmitter is disabled. Accuracy is +/-2 dB over speci-
fied operating voltage and temperature.
RX Power: RX Power data is calibrated to reflect the average optical power exiting the ferrule of a nominal
fiber[7]. The accuracy takes into account the fiber to fiber variation and also calibration test equipment accu-
racies. The RX Power is represented as a 16-bit unsigned integer with the power value equal to the full 16-bit
decimal value (0 to 65535)*0.1 μW. This yields a total range of 0 to 6.55 mW but is only valid if within the
operating specifications of the transceiver. Accuracy is +/- 2dB over specified operating voltage and tempera-
ture.
