Introducing the FLS-2600B Tunable Laser Source

Tunable Laser Source 3

RS-232 Connector Pinout

The RS-232 connector (serial port) at the back of the FLS-2600B uses a DTE

pinout configuration.

The source has a medium coherence length that avoids problems such as

connector-induced interference and it is relatively immune to vibration. Its

linewidth is made up of several longitudinal modes that are present

simultaneously, resulting in no mode-hop-related measurement problems.

It also features a high-accuracy encoder for consistency in your results.

Your module may also feature the possibility to enable or disable the

automatic level control (ALC).

The FLS-2600B Tunable Laser Source supports local control (via its front

panel) and remote control (through GPIB or RS-232 using SCPI commands

or the provided LabVIEW drivers).
