Notes
Temperature is measured internal to the transceiver.
Valid from = -10°C to 85°C case temperature.
Supply voltage is measured internal to the transceiver
and can, with less accuracy, be correlated to
voltage at the SFP Vcc pin. Valid over 3.3 V ± 10%.

Coupled into single-mode fiber. Valid from
100 µW to 500 µW, avg.
