VIAVI OSCA-710
OSCA-710
Measuring Optical Signal-to-Noise-Ratio (OSNR) in live Dense
Wavelength Division Multiplexing (DWDM) systems using polarization
multiplexed transmission (Pol-Mux) is an unsolved challenge. The
VIAVI Pol-Mux OSCA-710 is the first instrument to use a novel
spectral correlation technique (SCorM, VIAVI patent) to enable the
measurement of in-band OSNR, and per channel chromatic dispersion
of 40 Gb/s, 100 Gb/s, 200 Gb/s and 400 Gb/s coherent transmission
signals utilizing Pol-Mux in a live system, without shutting down the
network or individual channels.
Features:
- Industry’s first OSCA that measures
in-band OSNR on Pol-Mux signals - First instrument that measures
per channel CD - Characterize traffic without
shutting down the network or
individual channels - Supports PM-BPSK, PM-QPSK, and
PM-xQAM modulation formats - Tolerant of ROADM filtering and
of high CD and PMD
- Ultra-high resolution, coherent
OSCA for testing Nyquist- and
Super-Channels - WDM-Expert software for auto-
identification of symbol-rate in
mixed traffic pipes - Core and metro DWDM networks
with or without ROADMs - Undersea communication links
- Qualification of any fiber optic link
utilizing coherent detection
