Optical vendors juggle terabit trade-offs

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.
