OSA-610 High-Resolution OSA for 400 G Flex-Grid/Nyquist DWDM

The innovative VIAVI Solutions High-Resolution Optical Spectrum Analyzer (OSA-610) test solution for T-BERD/ MTS-8000 (V2) and -6000A mainframes can fully analyze the optical performance of current 10/40/100 G and future 400 G and higher optical transmission signals.

Based on coherent detection techniques, it provides unprecedented frequency resolution to precisely characterize optical signals (power level and frequency) and to analyze details never seen with previous field OSAs.

This is the industry’s first solution that brings lab-type performance to a field-form-factor for testing future high-speed DWDM systems.

Key Benefits

• Industry’s first field OSA that fully analyzes 400 G Nyquist WDM signals 
• It separates and analyzes narrow guard-bands in compressed super-channels enabling 400 G deployments 
• The smallest and lightest high-performance 400 G ready OSA available 
• From the lab to the field — True 400 G lab performance in a field-ready tester 

Key Features 

• Extended C-band acquisition range 
• Measures frequency, power level, and OSNR 
• Continuous and averaging test modes 
• Side-mode suppression ratio 

Applications 

• Qualify 10/40/100/400 G components and systems 
• Validate and deploy 100 G and 400 G Flex-Grid DWDM
