Hello Guys,  I[ve purchased at ebay two EDFA`s one DC another AC. DC seems workfine, i can have correct

information with my power meter. But AC version is giving me a very bad headeache..

See, how this is crazy :

edfa > status

Try use DC only power supply. AC's power sources current surges affect the intensity of the laser. Or use AC power normalization devices with batteries.
