Exfo has introduced its newest high-performance optical spectrum analyser (OSA) to assist network operators in their deployment of current and next-generation optical networks.
The FTB-5240S OSA test module, housed in either the FTB-200 compact platform or the newly launched FTB-500 Platform, is purpose-built for fast and accurate dense wavelength-division multiplexing (DWDM) network commissioning and high-speed network upgrades up to 40G.
Within the FTB-200 platform, it is the smallest, high-performance solution for spectral characterisation of next-generation networks. When equipped with in-band optical-signal-to-noise-ratio (OSNR) measurement capabilities in the FTB-500 platform, this versatile OSA can be combined with the FTB-8140 Transport Blazer to create a unique ROADM/POTS/40G test solution.
Exfo’s proprietary in-band OSNR test method delivers highly accurate measurements for next-generation systems in which noise can fluctuate from channel to channel. Traditional OSNR test tools tend to produce erroneous results, especially for ROADMs and 40G systems. The built-in polarisation diversity detection capabilities on Exfo’s new OSA enable customers to obtain accurate and automated OSNR measurements.
The FTB-5240S OSA benefits from ultra-fast scanning and analysis inside the new FTB-500 platform. A 90 dB dynamic range scan can be carried out within 1 second, including complete data analysis. The OSA also supports new modulation schemes, such as NRZ, duobinary, DPSK and QPSK, which present large line widths and often display multiple peaks. In-depth analysis ensures the correct identification and signal measurement of each carrier.
