4. Determine the laser pin config-uration from the laser diode data sheets and
install the Laser Diode into the socket as shown, according to the corresponding
Pin Code. Refer to Figure 4 on page 9.
5. The STYLE jumper on the back of the laser mounting PCB should be placed
according to the particular LD pin configuration being used. For pin codes A, B,
C, D, E, or H, set the STYLE jumper to the lower two pins. For pin code G, set
the jumper to the upper two pins.
6. The BYPASS jumper should be set only if the laser is modulated via the LD
DRIVER input on the LDM9LP. Please refer to the table below.
Operation Mode Bypass Jumper
Low noise, no modulation No (Removed)
RF Modulation via RF IN (BIAS-T) No (Removed)
Modulation via LD DRIVER input
2
Yes (Set)
2 If the LD driver being used has a noise reduction filter feature, the jumper may need to be removed to
ensure good performance.
