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.
Sumitomo Electric Industries has released a new series of ultra-high-fibre-count ribbon cables to meet the growing need for high fibre density in data centres. The new cables are available in fibre counts of 1152, 1728, and 3456.
The highest-fibre-count cable accommodates 3456 fibres in an outer diameter of 34mm while withstanding bending in any direction, and thus allows for easy installation in a 2-inch duct space.
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
