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.
Optical Technology Training
The in-depth 5 day training course in optical networking is a key enabler for well-designed and implemented national backbones, metro networks, fiber to the antenna (FTTA) and data center interconnects (DCI)
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.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
