The MS9740B maintains the same measurement and sensitivity ratio, functions, and size as its predecessor, the MS9740A, while reducing measurement processing times by 50%. This improves production line efficiency by optimizing the bandwidth settings of the optical receiver in the MS9740B spectrum analyzer, which is the most popular choice among customers. This performance improvement reduces inspection times for active optical devices and increases production line efficiency.
The deployment of 5G mobile services and next-generation cloud communications is expected to dramatically increase data traffic volumes. The networks supporting this infrastructure are experiencing a massive surge in traffic, requiring accelerated module production and shorter inspection times to enable on-time delivery, which is essential for the rapid expansion and adoption of optical modules with higher transmission speeds of 10G, 100G, and 400G bit.
The MS9740B benchtop optical spectrum analyzer is characterized by its wide dynamic range, high resolution, and fast scan speeds across a wavelength range of 600 to 1750 nm. The device supports multimode fiber input and is ideal for the fabrication and evaluation of VCSEL modules in the 850 nm band.
In addition to maintaining the same functions and performance as its predecessor, the MS9740B reduces measurement processing times by up to half (receiver bandwidth adjustment: 1 kHz or 200 Hz), while overcoming the problems of lower measurement sensitivity caused by the higher processing speed.
Furthermore, the MS9740B maintains the measurement menu displays for the active optical device (LD module, DFB-LD, FP-LD, LED, WDM, and optical amplifier (NF and gain)) for device evaluation. The device allows simultaneous measurements of all key evaluation elements, such as optical center wavelength, level, OSNR, spectrum width, etc., and displays these results on a single screen.
Main features of the MS9740B optical spectrum analyzer:
• Wide dynamic range and high measurement speed for the most commonly used optical receiver bandwidths in optical active device production lines
o SMSR measurement to a minimum of 45 dB
o Fastest measurement speed (sweep in Fast mode; total time required for wavelength sweep, analysis and data transfer to remote server) of 0.35 s (sweep with 30 nm wavelength)
• Same main functions and performance as its predecessor, for various production line environments
o Wide wavelength band (600 to 1750 nm) to evaluate all optical active devices
o Nine application menus for LD module, WDM, etc., and measurements.
