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.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
