Optical spectrum analyzer halves evaluation times
Increasing the production line efficiency of optical active devices for 5G mobile and cloud services, the MS9740B spectrum analyser from Anritsu was developed for evaluating the output characteristics of optical active devices used by optical communications systems.

This latest analyzer MS9740B keeps the same measurement-sensitivity performance, functions, and size as the predecessor MS9740A while shortening measurement processing times by 50 percent, slashing  optical active device inspection times and increases mass production-line efficiency. Production-line efficiency is increased by optimizing the most commonly used optical receiver bandwidth settings.

The spread of next-generation 5G mobile and Cloud communications services is expected to increase data traffic volumes massively. Networks supporting this infrastructure are experiencing explosive jumps in network traffic, which demands both increased module production and shorter inspection times to allow in-time delivery required for the rapid expansion and adoption of faster rate optical modules at 10G, 100G, and 400G bit.

The benchtop MS9740B features wide dynamic range, high resolution, and fast sweep speeds over a wavelength range of 600 to 1750 nm. It supports multimode fiber input and is ideal for manufacturing and evaluating 850-nm band VCSEL modules.

As well as keeping the same functions and performance as its predecessor, the MS9740B slashes measurement processing times by up to half (Rx bandwidth setting: 1 kHz or 200 Hz) while overcoming problems of decreased measurement sensitivity caused by increased processing speed.
