Service providers are undergoing a sea change.
Their networks, which traditionally have been based on turnkey network elements running software on purpose-built hardware, are moving to a software-centric model. In this model the true value lies in the software, while the hardware is typically of the commercial-off-the-shelf variety.
Network Functions Virtualization (NFV) is the name of this new architecture, which not only embraces the model of instituting network functionality in software and running it on industry-servers, but also allows applications and services to leverage those resources whenever and wherever they are.

“Ladies and gentlemen, the fasten seat belt sign has now been turned on. Please ensure your mobile devices are switched off for the full duration of the flight” It is the announcement that many passengers dread as they hurry to finish up one more e-mail, or send one final text or tweet, before the start of a flight and a few hours of absence from the connected world.
But from the end of 2016 this is set to change in Europe. Inmarsat announced on November 20 that it has signed a contract with Alcatel-Lucent to develop Long-Term Evolution (LTE) air-to-ground technology, which will be delivered in partnership with service providers and airlines in 30 European countries. Alcatel-Lucent will supply the ground LTE radio infrastructure, which consists of antennas situated 100 km apart. The system is capable of providing download speeds of up to 75 mbps to planes using 2x15 MHz FDD licenses which Inmarsat owns in the Mobile Satellite Service (MSS) S-band. This makes it not only the world’s fastest airborne broadband service, but a pioneer of future in-flight services for passengers and airline operations.
With adequate bandwidth and network speeds now a cornerstone of life for both businesses and consumers, optical transport is increasingly becoming a key solution for network operators.
The market for optical network equipment is expected to reach $15 billion by 2018, according to research firm, Dell’Oro. Optical transport of the 100G variety is expected to make up 80 percent of that demand.
Communications Industry Researchers (CIR) also recently released a report predicting that the market for 400G will hit $528 million by 2019, and the market for supporting optical components and silicon devices will reach $195 million that year.
Clearly, optical networking matters. It is easy to see why when looking at the recent achievements of Alcatel-Lucent’s agile optical networking technologies.
