Analyzer measures true OSNR in ROADM networks

JDSU has improved the measurement analysis for the in-band optical spectrum analyzer used in its T-BERD/MTS-8000 test platform. The OSA-320 module measures the true optical signal-to-noise ratio (OSNR) in reconfigurable optical add/drop multiplexer (ROADM) networks. It employs an optical polarization splitting method for measuring OSNR inside the optical channel (in-band OSNR), providing an accurate, true measurement.
