Silicon technology enhancements are enabling the evolution of coherent optical engines along three vectors. The first vector maximizes performance by leveraging the most advanced optical features, the second minimizes space and power, and a third integrates systems-level functions that were previously located in the shelf or card.
EllaLink has completed the marine installation stage of its trans-Atlantic cable system between Europe and Latin America.
UK cable operator Virgin Media has trialled network technology that provides new ways to roll out multi-gigabit speeds.
How will the next generation of optical networks provide the capacity to support unwavering increases in traffic, and does one solution really ‘fit all’? Keely Portway finds out
Could indium phosphide photonic integration be key to the ongoing development of high-performance coherent optics?
A wide range of cloud and video applications, together with the increased access speeds enabled by 5G, DAA, and next-generation PON, are driving the need for ever more optical bandwidth. To deliver this bandwidth, optical vendors are developing a broad range of coherent optical transceivers addressing different segments of the market, each with its own set of design considerations.
Keely Portway counts down some of the most-viewed and industry-shaping news stories of 2020
Full capacity? When it comes to 800G coherent, Keely Portway considers how to address capacity-reach
This white paper explains how an ultra-high baud rate, innovative features, and a high modem signal-to-noise ratio (SNR) enable Infinera’s 800G generation Infinite Capacity Engine (ICE6) optical engine to maximize wavelength capacity-reach – the maximum wavelength data rate that can be achieved for a given reach requirement.
Pluggable modules, expanded wavelength ranges and new system architectures seek to meet bandwidth needs, finds Andy Extance
As the pandemic underlines the value of the internet more than ever, its underlying technology is making one of its biggest transitions for years.
The data centre market is a particularly wide-ranging one, with one of the driving forces in recent years the emergence of the hyperscale data centre or cloud service provider.
As the world struggles to settle into the ‘new normal’, today’s optical networks need to be flexible in their architecture blueprint, while adapting to new technologies to provide the kinds of new capacity and service options to meet accelerated demand for higher bandwidth.
To address the undeniable growing demand for higher bandwidth, optical vendors have been playing their role with the development of various coherent optical transceivers for different areas of the market, each with its own set of design considerations.
The demand for bandwidth has unarguably skyrocketed in recent years, thanks largely to the increased appetite for online gaming, content streaming and social-media use.
The importance of reliable connectivity has never been more recognised than it is now. While ambitious targets have been in place across the world for fibre deployment for some time, the ongoing pandemic has served to push it to the forefront.
Looking into the future of telecommunications, it could be argued that AI and telcos will effectively transform each other, explains Raf Meersman
How do we, as an industry, build better broadband for a post-pandemic world? The answer could be fixed, suggests Stefaan Vanhastel
Altnets could be the key to connecting rural areas in 2021, argues Michael Armitage
