Optical Spectrum Analyzer (OSA)

The benchtop Anritsu Optical Spectrum Analyzer MS9740B features wide dynamic range, high resolution, and fast sweep speeds over a wavelength range of 600 nm 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^*1 while overcoming problems of decreased measurement sensitivity caused by increased processing speed.

Moreover, it retains optical active device (LD-Module, DF-LD, FP-LD, LED, PMD, WDM, Opt Amp, and WDM Filter) measurement menu screens for evaluating devices. It supports all-at-once measurements of key evaluation items, such as optical center wavelength, level, OSNR, spectrum width, etc., and displays these results at one screen.

Key Features of Optical Spectrum Analyzer MS9740B

• Wide dynamic range and high-speed measurement at optical receiver bandwidths used commonly by customers within production lines for optical active devices
  • SMSR measurement at 45 dB minimum
  • Maximum measurement processing time^*1 of 0.35s (sweeping 30-nm wavelength)
• Facilitates Stable Production of High-output LDs
  • ±1.4 dB SMSR reproducibility^*2
• Same key functions and performance as predecessor, supporting various production-line environments
  • Wide wavelength band (600 nm to 1750 nm) for evaluating all optical active devices
  • Nine application menus for LD-module, WDM, etc., measurements

Nine customized modes for solving typical tasks

Each type of measured optical device has its own spectrum features and, as a result, the set of parameters that need to be measured is different. Depending on the task to be solved, you can select Anritsu MS9740B from the analyzer menu any of nine pre-configured modes to measure what you need for a specific type of equipment.

These nine modes are designed to measure:
- DFB-LD (Distributed Feedback Laser - laser with distributed feedback)
- FP-LD (Fabry-Perot Laser Diode - Fabry-Perot laser diode)
- LED (Light Emitting Diode - LED)
- Laser Diode Module (Optical-transceiver - optical transceiver)
- PMD (Polarization Mode Dispersion - polarization mode dispersion (PMD))
- Optical Amplifier (optical amplifier)
- Optical Amplifier WDM (amplifier in wavelength division multiplexing mode)
- WDM Signal (Wavelength Division Multiplexed Signal)
- WDM Filter (optical filter for wavelength division multiplexing systems)

Each of these modes is configured in such a way that all important indicators of the measured device are conveniently displayed on one screen. This is very practical and saves a lot of time both in scientific research and in high-speed automatic testing during production.
