Notes
a. All specifications are typical with four seconds averaging time per point (where applicable), at a temperature of 23 ºC ± 1 ºC, with FC connectors and after
warmup time.
b. Displayed range. Values may be extrapolated.
c. Dynamic range is defined as the difference between the strongest signal and the weakest signal the receiver can detect. Extra averaging may be required.
Uncertainty (accuracy) is not guaranteed at limits of range.
d. C+L band.
e. Including EDFAs.
f. Additional gain setting time may be required prior to the first point of each band.
