All-optical networks, from access through to the transport layer, are critical for national digital economies. According to the World Bank a 10% increase in fixed broadband penetration would increase GDP by 1.21% in developed economies and 1.38% in developing ones.
Fiber is not simply about fixed-line broadband. Connecting dense clusters of cellular sites with high-speed fiber links enables much better customer experiences when using mobile networks.
Moreover, if done right, all-optical networks can help carriers operations become more agile.
