Amplifiers are no bar to fibre tester
The FTB-5500B polarisation mode dispersion (PMD) analyser is reckoned to be the only portable instrument on the market that can sweep through erbium-doped fibre amplifiers (EDFAs).

Network tester runs up to 43Gbit/s
Module provides advanced Sonet/SDH and OTN test functions in a single module to address the demands of commissioning and troubleshooting 43Gbit/s networks.

Chromatic dispersion can be characterised with high accuracy from a single fibre end and testing polarisation mode dispersion from a single end is also possible.
Optical links must be measured for PMD, especially when upgrading to transmission rates of 10Gbit/s or when deploying a cascade of amplifiers.
The FTB-5500B PMD analyser, a test module housed inside the all-in-one, FTB-400 field-testing platform, also provides the most advanced specifications in terms of testing time, measurement sensitivity and PMD range.
This revolutionary test instrument can characterise an entire link, with a dynamic range above 50dB and PMD range from 0 to 115ps, in less than 5s.
"This product represents a veritable breakthrough because it can be combined with a chromatic dispersion (CD) analyser inside our PC-centric, Windows-based FTB-400 platform along with a single light source to identify all dispersion issues on fibre links - even in the presence of optical amplifiers", said Etienne Gagnon, Director of Product Management at EXFO.
"No other test and measurement equipment manufacturer offers the same kind of flexibility and cost-effectiveness".
"Testing through EDFAs is critical in long-haul optical networks and the impact of amplifiers on overall network performance should not be underestimated", Gagnon added.
"We have carried out tests on 800km links delineated by more than 10 amplifiers, and our PMD analyser delivered results with the utmost accuracy.
This unmatched accuracy and EDFA testing are due to our patent-pending technology that measures minute PMD levels through separate auto- and cross-correlation data".
The FTB-5500B PMD analyser will be on display at booth 2341 during OFC 2003 from 25th to 27th March at the Georgia World Congress Centre in Atlanta.
