Why are Optical Network Systems important to Fibre Characterisation?

 

At OTT, we have a deep understanding of the technologies that are used to transmit ever higher volumes of data over optical fibres, as well as a deep understanding of all aspects of the physical fibre optic infrastructure. The interactions between these two critical aspects is built into all our courses, so that you benefit from the big picture, rather than being solely focused on one part of the equation.

OTT tick So, on the CFCE course not only will you learn how to test the fibre links thoroughly in accordance with the ITU G.650.3 Recommendation and relevant IEC International Standards, you'll also be able to analyse the results of the tests to assess the ability of the link to support different applications and technologies.

Higher data rates at 10Gb/s and above on direct detection systems have tight limits on the amount of chromatic dispersion and PMD allowed. DWDM and expecially CWDM systems use more wavelengths so you need to know about the infrastructure performance at those wavelengths. As we progress more into the world of 100Gb/s+ then even more of the fibre and physical infrastructure parameters can have an impact on system performance, particularly with the more widespread deployment of Raman amplifiers. Coherent systems may have the ability to compensate electronically for some dispersion, but there are still limits, and the optimum system design will be enhanced by detailed knowledge of all aspects of the fibre infrastructure.
