400nm low PDL all broadband light source development success
2012.11.25
ASE ultra broadband light source is a laser source with high stability, output optical power larger. ASE light source spectral width up to 410nm, covering 1240 ~ 1650nm. Power spectral density maximum can reach -25dBm/nm.ASE light source has very good low bias characteristics, it can be applied tooptical fiber passive devices (such as the production and testing of optical fiber coupler, an optical circulator, isolator, DWDM thin film filter, fiber grating, CWDM), can greatly improve the efficiency of the test fiber passive device. On the premise of the parameters of the test of IL, has been completely replaced SLED such high partial broadband light source.
