10. RECOMMENDED METHOD OF FIXATION
(1) QLD0593-xxxx-11 (with mounting plate option)
Apply 4-#2 or M2 screw with each torque of <0.1N.m.
(2) QLD0593-xxxx (Discrete module)
UV curable epoxy or heat curable epoxy are applicable to fix the module onto a heat sink.
Please contact QD Laser for further information.
11. OPTICAL POWER ADJUSTMENT PROCEDURE
With measuring optical power,
(1) Adjust DFB (and Heater) current so that the optical power becomes the maximum.
(2) Adjust SOA current to obtain the required power within the maximum rating.
(3) If needed, repeat the procedure of (1) to (2).
12. NOTICE
