Agere Systems Inc.
Characteristics
(continued)
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.
* Standard operating condition is 5.0 V reverse bias.
Ratio of thermistor resistance at 0 °C to thermistor resistance at 50 °C.
* Custom wavelengths available.
The ST errule key is not aligned to slow axis of fiber. Connector is intended for testing purposes only.
