Pin-out
Circular connector Lumberg SV50 (male, IEC 61076-2-106) for power supply and external modulation (pins Uanalog and UTTL).
Cable shielding and casing are connected and are galvanically isolated from the laser diode and the electronics.

Modulation
The laser has two AND-wired modulation input channels, Uanalog and UTTL.
Connecting analog voltage
The input for analog modulation allows applying an analog voltage Uanalog in a range from 0 V to 2.5 V) which allows a linear control of the laser output power from Pmin (Pmin is on the order of < 1% of Po) up to the maximum power given by the potentiometer setting.
Timing diagram
The laser is OFF in case of an open modulation input. If only one modulation input channel is used, the other has to be set to +5 V.
