Fibre characterisation in the coherent era

Fibre characterisation has been a part of my career since I joined York Technology in 1983. York had developed the FCm 1000, the first automatic fibre characterisation machine. This mighty machine could measure all of the fibre’s critical parameters, including end face geometry, mode field diameter and refractive index profile, as well as perform optical time-domain reflectometer (OTDR) testing, spectral attenuation measurements and, for multimode fibres, find the modal dispersion.

OTT enhances CFCE training course with hands-on learning

The Certified Fibre Characterisation Engineer (CFCE) training programme developed by Optical Technology Training (OTT) has been enhanced to provide comprehensive coverage of fibre characterisation systems available from the major test equipment manufacturers.

On the CFCE course, delegates learn about the test methods and equipment available from EXFO and Viavi Solutions, and gain hands-on experience using their systems to fully characterise fibre infrastructure representative of long-haul fibre systems.
