The VIAVI Pol-Mux OSCA-710 is the first Optical Spectrum and Correlation Analyzer that can perform in-band OSNR measurement in high speed, ROADM based DWDM networks using polarization multiplexing transmission formats without shutting down optical channels. This module uses a novel, proprietary spectral correlation measurement technique (VIAVI pat.) along with an ultra-high resolution coherent receiver for complete signal characterization in amplitude, frequency, phase and polarization.


  • Characterize and diagnose 40G, 100G, 200G, and 400G traffic without shutting down the network or individual channels
  • Only analyzer to incorporate spectral correlation technique
  • First instrument that measures in-service, in-band OSNR on pol-mux signals
  • First instrument that measures per channel, in-service, chromatic dispersion
  • Supports legacy traffic as well as upcoming modulation and optical spectrum management schemes


  • Installation, commissioning and maintenance testing in Core and metro DWDM networks with or without ROADMs
  • Testing undersea communication links
  • Qualification of any fiber optic link utilizing coherent detection
  • Service activation, optical launch power optimization and in-service Generalized Optical Signal to Noise Ratio (G-OSNR) validation for Submarine Cable Networks

Key Features

  • Power, wavelength, and in-band OSNR measurement for  any kind of data rates and modulation schemes, including polarization-multiplexed signals
  • Spectral correlation measurement (SCorM) technique 
  • Supports PM-BPSK, PM-QPSK, and PM-xQAM modulation formats used in 100, 200, and 400G systems
  • Tolerant of high chromatic dispersion (CD) and polarization mode dispersion (PMD)
  • Measures per channel  in-service CD
  • Coherent OSA design with ultra-high resolution bandwidth for testing Nyquist- and Super-Channels
  • WDM-Expert software for automatic identification of signal type (data rate) in mixed traffic pipes
