The Optical Internetworking Forum (OIF) took to the podium at this year’s NGON and DCI Europe conference in Nice to reveal the results of its 2018 Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) multi-vendor interoperability demonstration.
Construction has now officially commenced on the Japan-Guam-Australia (JGA) 9,500km undersea fibre optic cable system.
JGA is being co-built by Alcatel Submarine Networks (ASN), part of Nokia and the NEC Corporation. The JGA South (JGA-S) segment between Sydney, Australia and Piti, Guam, is a consortium cable, including AARNet, Google and RTI-C, whilst the JGA North (JGA-N) segment which runs between the Minami-Boso, Japan and Piti, Guam, is a private cable with RTI-C as the sole purchaser.
Nippon Telegraph and Telephone (NTT) and six partners have established a new world record of 118.5Tb/s for the largest transmission capacity achieved over an optical fibre of standard dimensions.
Though the optical fibre had the same diameter as standard singlemode fibre, its structure was not standard. The design contained four cores (light paths) running along the fibre’s length.
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.
