Use the LDMOUNT-CU Custom Butterfly Card with the LDMOUNT-5A laser diode mount if the standard butterfly wiring of Type 1 or Type 2 doesn’t match your laser diode. It allows you to configure the connections between any 14-pin butterfly package and the LDMOUNT D-sub connectors.
The Custom Butterfly Card requires you to hand solder connections with 22 AWG wire or smaller. As an example, the figure below shows a Custom Butterfly Card wired for a standard Type 1 Laser.
Working down the left (blue) column of connections:
- Therm- is connected to butterfly pin (BF) 5
- Therm+ is connected to BF 2
- BF 1 is connected to TEC+
- BF13 is connected to LDA
- BF10 is connected to LDA
- BF 14 is connected to TEC-
- PDA is connected to BF 3
- PDC is connected to BF4
Working down the right (red) column of connections, the only connection that hasn’t already been described is:
- BF 11 to LDC
These connections match exactly the schematic for the standard Type 1 laser diode. For any given pinout of a butterfly package, the Custom Butterfly Card can be wired to match.
