JDSU has introduced improved measurement analysis for its in-band optical spectrum analyser (OSA) for the T-BERD/MTS-8000. The OSA-320 module, a high-performance optical spectrum analyser, incorporates a unique and highly accurate method for measuring the 'true' optical signal-to-noise ratio (OSNR) in reconfigurable optical add/drop multiplexer (ROADM) networks.
The OSA-320 module is designed to test optical performance in the agile optical network (AON), a dynamically reconfigurable DWDM network that is designed to accelerate triple-play service deployment, simplify network management, and enable advanced wavelength applications at significantly reduced costs. In the AON, multiple ROADMs with different ‘filtering’ technologies can be cascaded in a link, creating OSNR measurement problems for conventional OSA devices that employ out-of-band methods. Even the most recent OSA devices using the 'shoulder method' may not provide accurate OSNR results for different ROADM filter shapes at high data rates. With JDSU’s improved measurement analysis it is possible to accurately measure the ‘true’ OSNR in all deployment scenarios of ROADM networks (from 10 G to 40 G), regardless of the filter type integrated into the ROADM.
In ROADM networks, each channel may traverse different routes, optical amplifiers, and add-drop filters, resulting in different OSNR for each channel. Conventional OSA measurements are unreliable, as they indicate OSNR values that are too high – up to 10 dB above the true OSNR. JDSU’s OSA-320 follows an optical polarisation splitting (OPS) method for measuring OSNR inside the optical channel (in-band OSNR), providing the highly accurate, ‘true’ OSNR.
