Australia’s broadband network operator NBN Co has started enabling DOCSIS 3.1 cable technology on its Hybrid Fibre Coaxial (HFC) network in a move to increase activations. The incumbent intends to focus on doubling the downstream capacity on the network, which is due for completion in 2020.
CableLabs has published two new specifications to ‘dramatically increase’ capacity of the fibre access network with point-to-point coherent optics technology, allowing for 100Gb/s per wavelength.
Using amplitude, phase, and polarisation to enable much higher fibre capacities, coherent optics can help to improve streaming, video conferencing, file uploads and downloads and future usage needs for technologies such as virtual and augmented reality, and by gaining more capacity from existing fibres, the need to lay more can be eliminated.
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
