ECOC 2019 THE YEAR AHEAD ANALYSTS
With the new year fast approaching, it’s tempting to speculate on what developments 2022 will impact the fibre optics industry, so we asked the experts. Here’s what two leading analysts who specialise in forecasting future technology and markets in the fibre optic communications sector think we can look forward to in the next 12 months and beyond. THE YEAR AHEAD: PART ONE The Rise of Coherent 400G and Co-Packaged Optics?
2022 – THE YEAR OF COHERENT 400 GBPS DWDM Jimmy Yu, vice president, Dell’Oro Group “Now that the technology is ready and the products are available, 2022 will be the year for coherent 400 Gbps DWDM. It will be used everywhere— from data centre to metro to subsea. This wasn’t always the case. Although 400 Gbps-capable line cards have
as data centre interconnect (DCI). However, to be suitable for long-haul routes, a 400 Gbps signal would need the ability to travel more than 1,000 km without regeneration. This long span became possible with a new generation of coherent technology, delivering 800 Gbps- capable line cards that could send
been available since 2017, the technology could only transport a 400 Gbps signal about 300 kilometres (km), which was perfect for metro distances but not good enough for long-haul routes. Hence, since 2017, use of 400 Gbps wavelengths has been increasing in metro areas, especially in applications that required a large amount of bandwidth such
