VIAVI offers a full range of OSAs tailored for spectral measurements in CWDM systems in the access network as well as DWDM systems in high-speed backbone networks with datarates up to 40Gbps or 100Gbps. The VIAVI OSA-500RS accurately validates optical performance under extreme conditions as networks are continually pushed to higher levels and ROADMs are added for uninterrupted service. The OSA-500RS delivers highly valuable benefits to operators and NEMs who commission, install, upgrade, or troubleshoot anywhere within the fiber network ecosystem.


  • OSA-500R/500RS with in-band OSNR method to measure the true in-band OSNR in ROADM-based systems

  • InBand OSNR measurement time is significantly reduced using a fast polarization controller

  • Internal online wavelength calibration guarantees highest wavelength accuracy and requires no recalibration, thus significantly reducing service costs

  • High filter selectivity and lab optical performance over the full band, from 1250 to 1650nm, in a field-modular design

  • Measurement of the true in-band OSNR in Agile Optical networks including ROADM testing and dispersion compensating modules

  • DWDM and CWDM system testing during installation, maintenance, and network upgrade

  • Automated DWDM passive and active component testing

  • System verification testing according to the customer's preset limits

  • Verification of ROADM configurations in Agile Optical Networks

  • Full-band optical spectrum analyzer for the ONT platform, MTS-8000 / T-BERD 8000, MTS-6000 / T-BERD 6000

  • Key Features

  • New Optical Polarization Splitting method (OPS-method, VIAVI pat pending) for measuring the true in-band OSNR in ROADM based networks

  • Future-proof design with a wide tuning range of 1250 to 1650 nm that is suitable for all optical DWDM and CWDM (Metro) networks up to 100GBps

  • Channel drop option for troubleshooting and fault location. lsolation of a single channel out of the entire spectrum for further in-depth signal analysis with BERT or a Q-factor meter

  • Software option for PMD testing based on the fixed analyzer PMD test method

  • Built-in optical component test applications for laser diodes, LEDs, and optical amplifiers
