CD causes light pulses to broaden when traveling within the fiber, up to a point where bit error rate increases. CD can be compensated over a wide wavelength range, but this can be costly, so precise measurement is key.
Polarization Mode Dispersion
Due to local changes in the fibers, index of refraction and physical stresses on the cable, the two polarization states of light travel at slightly different speeds; this spreads the pulse over time and distance, eventually increasing BER.
Distributed PMD Analysis
The first distributed PMD analyzer on the market breaks down PMD assessment to pinpoint faulty sections on the link, enabling cost-effective, targeted upgrades.
End-to-End Fiber Characterization (OTDR)
When distance is an issue, the FTB-7600E OTDR, with a dynamic range of up to 50 dB, is the solution. Taking full advantage of EXFO’s industry-leading expertise in OTDR development, this module can test over distances of up to 250 km.
Remote OTDR with Fiber-Optic Cable Monitoring
Remote fiber characterization, testing, 24/7 monitoring and alerting functions. Delivers the measurement of fiber, splice and connector aging.
