Display resolution (pm) 1

Effective spectral linewidth FWHM

(GHz) 1.3 (typical)

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.
