Viavi OSA-500R Optical Spectrum Analyzer

Overview

Viavi's OSA-500R is a full-range optical spectrum analyzer designed for spectral measurements in CWDM, DWDM, and ROADM systems with datarates up to 100 Gbps. It features VIAVI's proprietary Optical Polarization Splitting (OPS) method for measuring true in-band OSNR in ROADM-based networks, with wavelength coverage from 1250 to 1650 nm. The modular design combines laboratory optical performance with field portability for installation, maintenance, and network upgrade testing.
