When the world’s first transatlantic cable failed in 1858 – just three weeks after it had been inaugurated with a congratulatory telegram from Queen Victoria to US President James Buchanan – it took eight years until a replacement was operational. The cable, made of copper wires insulated with natural latex from the gutta-percha tree, probably had manufacturing faults and burnt out when its electric load was cranked up to compensate for rapidly deteriorating signal strength.

Carriers are exploring a fundamental change to how they manage and operate their networks.
Distributed routing protocols that enable connectionless packet-based networking have long been the norm for carrier traffic. Now operators are exploring the idea of a central control instead of sprinkling intelligence across the equipment in their networks.
Industry observers have described 2013 as ‘the year of 100G’. According to Infonetics Research, spending on wavelength-division multiplexed (WDM) equipment accelerated dramatically as a result of new 100G deployments. In fact, the market-research firm says that worldwide spending on 100G equipment is close to 15 per cent of all optical hardware spending, which itself totalled $3.3 billion (€2.4 billion) in the second quarter of this year.
Thomas J. Watson, chairman and CEO of IBM, famously said: ‘There is a world market for about five computers’. While this statement would have been accurate at the time (1943), viewed through the lens of history it seems rather silly. In any case, the statement is probably apocryphal. There is no record that Watson ever said anything of the sort.
Oleg Khaykin, CEO of Viavi Solutions, speaks candidly to Fibre Systems about how to compete in the challenging world of communications test and measurement
