Circular connector Lumberg SV70 (IEC 61076-2-106) for power supply and external modulation (pins Uanalog and UTTL) as well as RS232 interface.
Cable shielding and casing are connected and are galvanically isolated from the laser diode and the electronics.
|red||2||+ 5 V|
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.
