C+L Band Broadband Light Source

S-103 - Notice

ASE broadband source slot module of FOTS system can offer special function that is able to change optical output spectral feature variously, which is change optical output spectral feature variously, which is followed by user’s driving embedded pump LD freely. The output power of each pump LD is controlled separately by the program that is set up by user. In the case optimum ASE source output features such as wide broadband (> 80 nm @ -10 dBm/nm) and stable output power (< 0.02 dB) is needed, it is made up so that the provided Default mode along with User mode can be chosen and set up. More stable application of ASE source is possible through the combination of monitoring of ASE output power, alarm status and pump LD status with real-time optimal feedback. The embedded FPGA processor makes high speed control possible and enables monitoring and feedback routine operated stably.
