Swept Test System (Tunable Laser Test System)

 
■ The Santec Swept Test System (Tunable Laser Test System) has been developed to streamline photonic testing, providing a complete solution where high-speed analysis, high resolution and accuracy are key. Combining one of Santec’s tunable lasers (TSL-710, TSL-550 or TSL-510) with a Santec optical power meter (MPM-210), a polarization control unit (PCU-100) and custom software, the complete Swept Test System optimizes WDL and PDL measurement for use in both R&D and production environments. Using real-time referencing, while simultaneously acquiring output power from the tunable laser and the transmitted optical power through the DUT, the system provides high accuracy in WDL and PDL analysis using the Muller Matrix Method.
 
■ A simplified system is available by combining a Santec Swept Processing Unit (SPU-100) and any basic power meter or photodetector; the resulting Swept Test System variant can be used for WDL measurements. Over-sampling and rescaling algorithms are used to maximize testing throughput while maintaining measurement integrity. The system is particularly suited to transmission spectra characterization such as those required for DWDM components and High Q photonic devices. Rapid sweep and accurate measurement saves time and ensures the integrity and validity of your device characterization.
