Anritsu introduces optical spectrum analyzer MS9740B that improves time-to-market of high-speed optical devices

ALLEN, TX—Anritsu Company introduces the Optical Spectrum Analyzer (OSA) MS9740B that combines high-end measurement-sensitivity performance, expanded functionality, compact size, and high-speed measurement capability. With the MS9740B, design and manufacturing engineers can accurately verify and improve time-to-market of 100G/400G optical modules designed into 5G and Cloud communications systems. 

To improve measurement speed by 50%, Anritsu enhanced the optical receiver bandwidth settings of the MS9740B. This design approach significantly improves throughput while maintaining high performance. The benchtop OSA has wide dynamic range of >70 dB and maximum measurement processing time of 0.35s (sweeping 30-nm wavelength). Optical sensitivity is as low as -90 dBm. Accurate side mode suppression ratio (SMSR) measurements can be made at 45 dB or more, helping engineers have confidence in their designs.

The MS9740B is designed for high-throughput production environments. It supports multimode fiber input and is ideal for manufacturing and evaluating 850-nm band VCSEL modules. Its wide wavelength range of 600 nm to 1750 nm, however, makes the OSA well suited for evaluating all active optical devices. Nine application measurement modes—including LD-Module, DFB-LD, FP-LD, LED, PMD, WDM, Optical Amplifier (NF and Gain), and WDM Filter – are supported by the MS9740B, making it well suited for high-volume manufacturing.

Verifying high-speed optical devices is simplified with the MS9740B. All measurement modes can be easily accessed via intuitive menu screens. Further simplifying device verification is that the OSA supports all-at-once measurements of key evaluation items, such as optical center wavelength, level, OSNR, and spectrum line width, with results displayed on a single screen.
