Characteristics
Minimum and maximum values are testing requirements. Typical values are device characteristics and are results
of engineering evaluations; they are for information purposes only and are not part of the testing requirements. All
parameters are beginning of life, unless otherwise specified.
Table 2. D2587-Type Electrical Characteristics (at 25 °C laser temperature)
1. Standard operating condition is 5.0 V reverse bias.
2. The (relative) etalon slope is defined as the local slope (in GHz – 1) at the Agere-specified ITU operating point, divided by the R_R
3. Ratio of thermistor resistance at 0 °C to thermistor resistance at 50 °C.
