Notes:
1. At 23 °C ± 1 °C and 1550 nm with FC/PC connector unless otherwise specified.
2. Resolution, uncertainty and linearity are functions of input power; uncertainty is
valid at calibration conditions.
3. Traceable to NIST; up to 20 dBm for GeX.
4. Power of > –45 dBm for Ge, > –30 dBm for GeX and > –57 dBm for InGaAs.
5. In high-power mode.
6. As defined by Telcordia TR-TSY-000887, rms for lasers and at -3 dB for LEDs;
typical values for LEDs.
7. After a warm-up time of 6 minutes.
8. Typical value, at 1550 nm for SM and 850 nm for MM.
9. Typical value.
10. For fiber length ≤ 120 km.
