Optical Pol-Mux Spectrum Analyzer

Optical Pol-Mux Spectrum Analyzer from Viavi

Viavi’s Pol-Mux OSA-710 is the first Optical Spectrum 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.

Highlights:

• Characterize and diagnose 40G, 100G, 200G, and 400G traffic without shutting down the network or individual channels
• 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

Applications:

• 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

Key Features:

• Power, wavelength, and in-band OSNR measurement for  any kind of data rates and modulation schemes, including polarization-multiplexed signals
• 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
