Notes
a. Specifications are valid at 23 °C ± 1 °C after one-hour warmup time.
b. FWHM: full width at half maximum. The specification is valid at 1580 nm, where
it corresponds to 12 pm.
Given in HR mode.
Typical 700 MHz at 1610 nm and 2 GHz at 1520 nm.
Linewidth is Gaussian-like and produces a coherence length of about 15 cm
when propagating into SMF-28 fiber type.
c. Expressed as ± half the difference between the maximum and
minimum values measured.
d. User calibration may be required.
e. Operating in continuous sweep.

f. 1 nm step, one complete step through GPIB in manual mode with FLS-2600B.
g. In normal mode. Operating in high-resolution mode (HR) typically reduces power level
at extreme wavelengths, therefore shortening the tuning range by a few nanometers.
h. At connector output of the source.
i. In the 1515 nm to 1610 nm range.
SSE: source spontaneous emission
RBW: spectral resolution bandwidth
j. ALC: Automatic level (or power) control.
k. For 1 dB step 10 % to 90 % response time.
