Anritsu launches MS9740B Optical Spectrum Analyser to halve evaluation times

Technologies and Products

Anritsu has launched its new Spectrum Analyser MS9740B, 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 the predecessor (MS9740A) while shortening measurement processing times by 50%. The MS9740B also improves production-line efficiency by optimising the optical receiver bandwidth settings, most commonly used by customers. Anritsu says this performance upgrade “slashes optical active device inspection times and increases mass production-line efficiency.”

The company says that 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 Optical Spectrum Analyser 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.

As well as keeping the same functions and performance as its predecessor, the MS9740B reduces 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.

Moreover, the MS9740B retains optical active device measurement menu screens for evaluating devices, such as LD-Module, DFB-LD, FP-LD, LED, WDM and Optical Amplifier NF and Gain. The device also 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.

The tester offers a wide dynamic range and high-speed measurement at optical receiver bandwidths used commonly by customers within production lines for optical active devices, with SMSR measurement at 45 dB minimum.

It is specified to offer what Anritsu calls “the fastest measurement speed available”, sweeping in fast mode, with a total time required for wavelength sweep, analysis, and data transfer to remote server of 0.35s (sweeping 30-nm wavelength).
