Ultra-broadband ASE source:U-ASE-G01-FiberPro


The U-ASE-G01-FiberPro is a continous wave (CW) ultra-broadband light source designed for wavelength-dependent characteristics measurement of special optical fibers(Yb, Er, Tm, etc.) and devices.

This wide-band, highly stable light source, has very long lifetime(typically>100,000 hours), provides highly reliable non-polarized, CW ASE light.
