After approximately one second, the
Active
LED lights up on the fascia
to indicate that the source is active at the wavelength, at the output
power, and in the mode currently selected.

Setting the Source
Press
Mode
to toggle the source between tunable and ASE (amplified
spontaneous emission) operation.
In ASE mode, the laser cavity is appropriately modified so that the laser
operates in a non-coherent broadband mode, with a spectrum typical of a
non-flattened erbium-doped fiber source. In ASE mode, the FLS-2600
operates at 1550 nm with an output power over 4 dBm. The only
operations possible in this mode are source activation/deactivation and
mode selection.

Note:
Changing the source mode when the source is active will switch off the
source.
