Windstream Wholesale has completed a live network trial in which it successfully deployed 400Gb/s single-wavelength transmission over 1,027km across its long-haul network between Phoenix and Los Angeles.
Researchers from Duke University and Facebook’s Connectivity Lab have created a new plasmonic metasurface that achieves record high light efficiency over the entire centimetre-scale metasurface.
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 glance at the current market for fifth-generation coherent optics, and some of the latest developments available
Lumentum is to acquire Coherent for $5.7bn, bringing the latter’s photonics and lasers businesses into the former’s telecom, datacom, and 3D sensing photonics businesses.
Optoscribe has launched a monolithic glass chip for low-loss coupling to silicon photonics (SiPh) grating couplers.
Optical technology vendor, Luna Innovations has acquired OptaSense from parent company, QinetiQ for £29m.
This paper describes how silicon photonic (SiPh) opto-electronic integration and packaging, with its improved RF performance, is designed to enable next-generation coherent transmission beyond 100Gbaud and provide network operators with the ability to avoid “half-step” capacity upgrades and allow them the full step upgrades they need without sacrificing reach or stranding network bandwidth when migrating from current-generation solutions.
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
