Santec's scanning test systems are designed to simplify photonics testing and provide a complete solution where high speed analysis, high resolution and high accuracy are key, Santec's tunable lasers (TSL-770, TSL-570, etc.) coupled with an optical power meter (MPM-210H), a polarization controller (PCU-110), and a customized version of the software make up a complete scanning The test system is optimized for WDL and PDL measurements and is suitable for both R&D and production environments. The system uses a real-time reference to simultaneously acquire the output power of the tunable laser and the optical power transmitted through the DUT, providing more accurate WDL and PDL analysis using the Mueller matrix method. Test data throughput is maximized by resampling and tuning algorithms while maintaining measurement integrity.Santec's MPM-210H power meter mainframe can also be used in conjunction with the 4-channel galvanometer module MPM-213. The combination of the scanning test system and the MPM-210H/MPM-213 is suitable for testing the performance of fiber optic components such as transceiver photodiodes (ROSA/Coherent receiver, etc.) or optical channel monitoring.

What is WDL and PDL? - WDL: Wavelength Depend Loss, is the degree to which the insertion loss of a device varies with wavelength. PDL: Polarization Depend Loss, is the maximum transmission difference of the device in different polarization states. These two indicators reflect the wavelength stability and polarization stability of the device, and have an important impact on the performance of the optical communication system. Generally speaking, the smaller the values of these two indicators, the better the performance of the device.

The Santec TSL-550 can be used for testing optical devices and modules such as tunable filters, interleavers, fiber gratings, couplers, separators, isolators, optical switches, etc. It can also be used to characterize silicon photonic materials, including microcavity ring resonators. It can also be used for characterization of silicon photonic materials, including microcavity ring resonators. In addition, it can be used in spectroscopy, interferometry and other fields.

The keysight 86100D oscilloscope is available with two user interfaces, the classic DCA user interface and the new FlexDCA user interface. The classic DCA user interface is fully compatible with the 86100C DCA-J oscilloscope and is very familiar to use. the FlexDCA user interface is vector-based and offers additional signal analysis features such as de-embedding/embedding, equalization, phase-locked loops, phase noise, customized analysis, and more. It is possible to switch between the two user interfaces according to your needs with the touch of a button on the screen.

800G slowdown 400G rebound, optical module is the core component in the optical communication system, and its performance and cost directly affect the development of optical communication. With the increasing demand for high-speed, low-power and low-cost optical modules in 5G, data centres and other fields, the optical module industry is facing new challenges and opportunities.

A wavelength meter is an instrument that measures the wavelength of radio or light waves using the phenomenon of resonance. It can accurately and rapidly measure the wavelength of microwave signals or optical signals, and is an important test tool in the field of optical communications and photonic technology.
