QUEBEC CITY, Aug. 10, 2010 — Exfo Inc. has announced a significant processing speed increase for its FTB-5240S optical spectrum analyzer, which is purpose-built for fast and accurate dense wavelength-division multiplexing (DWDM) network commissioning and high-speed network upgrades up to 40 Gb/s.

Thanks to proprietary platform technology advancements, this module now operates ten to twenty times faster, depending upon the application being run.

When equipped with in-band optical-signal-to-noise-ratio (OSNR) measurement capabilities, the analyzer is a powerful, field-grade 40-Gb/s and reconfigurable optical add/drop multiplexer (ROADM) network commissioning tool. The proprietary in-band OSNR test method delivers accurate measurements for next-generation systems in which noise can fluctuate from channel to channel.

Traditional OSNR test tools produce erroneous results, especially for ROADMs and 40-Gb/s systems. The built-in patent-pending hybrid detection capabilities enable customers to obtain accurate and automated OSNR measurements from a next-generation network.

The processing speed increase enhances the instrument’s applications. All acquisitions are now performed ten times faster, re-analysis using different parameters is now 14 times faster, and trace loading is now 20 times faster.

Housed in either the FTB-200 compact platform or the FTB-500 platform, the instrument includes application software that enables setups and test configurations to be easily defined and stored, and that includes a “favorites” button that enables direct access to the user’s defined configuration list and a “discover” button that replaces any setup, ensuring intelligent analysis, and automatic channel discovery and identification.

The high-power option is suitable for multiservice and CATV operators and allows up to 23-dBm input power per channel. The analyzer covers DWDM applications and all channel spacings, from 50-GHz DWDM to coarse wavelength-division multiplexing.

Wavelength range is from 1250 to 1650 nm, and dynamic range per scan is >90 dB.
