SWL-C波长扫描激光器测试报告

SWL-C Testing Data

OSO Technology Co.,Ltd.

The oscilloscope will show the profile of the C-band (1525nm-1570nm) output from SWL-C.

(2) Input laser beam to an Etalon (100GHz) and

a FBG (1527.975nm) wavelength marker:

(5) DC tuning Demo:

•Slide Control Switch to EXT. position in the front panel. •Input a 0 to +40Vdc tunable voltage to the EXT. IN at the real

panel.
