Problem Solution
3 On power-up, the laser
displays “Initializing” for
longer than 2 minutes.
Re-initialize the laser:
• Switch off the laser using the key.
• Wait at least 30 seconds.
• Power on using the key.
If the laser does not initialize, contact the local JDS
Uniphase representative or call the service hotline.
4 When the Execute button is
pressed on the SOM, an
error message “increase
span” is displayed on the
SOM.
Check optical connections:
Verify that the green end of the PM fiber is
connected to the Optical Output port of the tunable
laser source.
Verify that the other end of the PM cable is
connected to the Laser In port of the source optics
module.
• Clean the fiber connectors.
• Reconnect and try again.
If the problem persists, check the parameters of the
source optics module:
• Verify that the start wavelength is 1519.5 nm for C-
band or 1540.8 nm for L-band.
• Verify that the stop wavelength is 1575 nm for C-
band or 1635 nm for L-band.
If the parameters are not as indicated, reset the
parameters and try again.
If the problem persists, check the power from the laser
power:
Use a power meter to measure the power from the
laser.
If the laser power is significantly (>3 dBm) lower
than the value displayed on the laser display, the
laser needs repair.
Contact the local JDS Uniphase representative or the
service hotline to arrange return of the laser to the
factory.
