Optical spectrum analyser

30 April 2019 Test & Measurement

Anritsu announced the sales launch of the new MS9740B spectrum analyser which has been developed for evaluating the output characteristics of optical active devices used by optical communications systems.

The MS9740B keeps the same measurement sensitivity performance, functions and size as its predecessor MS9740A while shortening measurement processing times by 50%, further improving production-line efficiency by optimising the optical receiver bandwidth settings most commonly used by customers.

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 10 Gbps, 100 Gbps and 400 Gbps.

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

The MS9740B retains the optical active device (LD-Module, DFB-LD, FP-LD, LED, WDM and optical amplifier) measurement menu screens as its predecessor for evaluating devices. It supports all-at-once measurements of key evaluation items, such as optical centre wavelength, level, OSNR, spectrum width, etc., and displays these results on one screen.
