Fibre Systems Summer 2017

FEATURE

Squeezing the margins

Optical networking is becoming smarter. Guesstimates and offline calculations are on their way out; to be replaced by real-time computation and machine learning applied to ‘big data’ generated by the network itself, which can be used to optimise performance in ways that weren’t possible before.

FEATURE

Cable companies consider coherent optics

Modern hybrid fibre coaxial (HFC) cable access networks are very different to their original home television delivery-focussed incarnation, observes Alberto Campos, distinguished technologist at CableLabs, in Louisville, Colorado. ‘Broadcast TV demand has been decreasing,’ he told Fibre Systems. ‘Online or on-demand viewing and broadband internet have been increasing and are the biggest residential items.’ Our appetite for data seems insatiable, with internet connection speeds accelerating at approximately 45 per cent annually, he says.
