EXFO Introduces High-Performance OSA

EXFO Electro-Optical Engineering (EXFO) introduced a new high-performance optical spectrum analyzer (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 newly launched FTB-500 Platform, is designed for DWDM network commissioning and high-speed network upgrades up to 40G. When equipped with in-band optical-signal-to-noise-ratio (OSNR) measurement capabilities in the FTB-500 platform, the analyzer can configured to create a ROADM/POTS/40G test solution.

EXFO said its 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 polarization diversity detection capabilities on the EXFO OSA enable 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, duo binary, 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.
