*
Where f is the Modulation Frequency in KHz.
Note 1: Typically there will be an
additional 0.004 UI rms when
using monitor gain.
Note 2: Typically there will be an
additional 0.004 UI rms when
using equalisation.
Note 3: Typically there will be an
additional 0.004 UI rms at
STM-1 optical with light
levels less than -22 dBm.
Note 4: Typically there will be an
additional 0.004 UI rms at
STM-4 with light levels less
than -16 dBm.
Note 5: Typically there will be an
additional 0.008 UI rms at
STM-4 with light levels less
than -22 dBm.
Note 6: Typically there will be an
additional 0.01 UI due to
temperature variation.
Values are RMS jitter in UI rms
measured with 12 kHz filter present.
