Starting-up and Debugging
After finishing all above preparation works, electrical test can be processed.
Turn on the power switch on back panel, indicator shows red light, screen
lights up, it means the whole device is powered up normally.
Then turn on the key switch on front panel and adjust the button on it, select
necessary working status.
Output optical power tested by optical power meter should equal or higher
than nominal output power. Through the screen and buttons of system
controller, key parameters like output optical power, laser bias current, cooling
current and laser temperature of current unit can be viewed.
Attention: Without specialized equipment, we do not suggest user adjusting
modulation degree. Our devices are already adjusted modulation degree to the
groove before leaving factory.
10. Notes for Using
Optical transmitter is precise optoelectronic equipment, it is required to
strictly follow the requirements of operation specification when using, if it is
operated incorrectly, it might damage the transmitter and cause personal
injury.
During the process of working or testing of optical transmitter, it is not
allowed to directly watch optical output port and bare fiber, or else it will
damage retina and cause blindness accident.
To prevent laser damage from overdriving RF, it is seriously forbidden to
input signal that is more than 82dBuv, RF connector insertion and extraction
when working normally and incorrect power-up operation are forbidden as well,
Performance of optical connector has big influence on the performance of
