Fast Wavelength Meter 1250-1650nm (182-240THz)

With the growing demand for communication data, a larger capacity optical communication transmission system is needed, which has driven optical component and network equipment manufacturers to use coherent communication modules based on wavelength tunable lasers in transmission backbone networks. At present, the scope of use of wavelength tunable lasers and coherent modules will further sink to the metropolitan area network and even access network. A very important test for tunable lasers is accurate measurement and wavelength calibration. With the continuous increase in communication channels, from the initial 40 waves to the current highest 800 waves, fast and accurate wavelength testing is more critical than ever. Our fast wavelength meter is designed and developed to meet this new test demand. The product is based on Fizeau interferometer technology, combining temperature-controlled interferometers, multi-stage compound interferometer cavities and linear array CCD detectors. Unlike traditional ordinary wavelength meters based on Michelson interferometers, this product adopts a fully solid-state structure and non-mechanical moving parts optical design, which enables it to ensure very high measurement accuracy (1pm) while having an ultra-high-speed measurement rate (up to 1kHz wavelength refresh rate). Combined with external triggering and fast power detection functions, this product becomes the best choice for accurately observing synchronous transient changes in wavelength and power.

Product features：High wavelength accuracy: ±0.33ppm (typical value: ±0.5pm), can be used for wavelength calibration and measurement、 All-solid-state structure, optical design with no mechanical moving parts. Fast test speed: 1kHz refresh rate, suitable for transient wavelength and power testing, greatly reducing the test time of iTLA, DBR and coherent communication modules、 Support external triggering, and can be used with SMU precision source meter for synchronous testing、 Suitable for iTLA and tunable laser fast wavelength testing、 Support broadband mode, can test 25Gbps modulated optical signals、 Supports drift test and Max. Min. Value Display、 0.1pm/12.5MHz wavelength resolution.
