Portable CD analyser characterises 500km link with 8 amplifiers
17 June 2002 -- Exfo Electro-Optical Engineering, Quebec City, Canada, says its new FTB-5800 Chromatic Dispersion Analyser has characterized an entire long-haul network belonging to Telus.
Test trials on a 500km link proved to be conclusive when the Chromatic Dispersion (CD) Analyser, a module contained inside the FTB-400 field-testing platform, swept through eight erbium-doped fibre amplifiers (EDFAs) with accurate and repeatable measurements. "This marks the first time a field-ready CD Analyser tests an entire link including amplifiers," said Exfo.
"This represents a remarkable achievement since there's no known limit to the distances that our CD Analyser can measure," said Mario Larose, VP Marketing at EXFO. "Long-haul and ultra-long haul carriers as well as network service providers have been wanting to characterise entire links, not only sections of it, for the longest time. Up until today, this was impossible using a field-testing instrument."
The CD Analyser can also be combined with a Polarisation Mode Dispersion (PMD) Analyser inside the FTB-400 platform to handle all dispersion testing needs. A single CD-PMD Analyser Source completes the test set to allow significant savings in testing time and cost.
