Opening Up 5G RAN Development

31 Oct 2019 Sponsors: ECI Telecom

Behind the headline grabbing transition from 4G to 5G wireless networks there is a significant shift in the radio access network (RAN) from a centralised architecture to a virtualized/cloud (vRAN) architecture. This shift in architecture enables the opening up of the RAN and associated infrastructure solutions, including xHaul networks and edge computing, through public and […]

Supersizing the C-Band

Tuesday, 21 May 2019 Sponsors: Huawei

Over the past seven years the optical transport industry has made huge strides in increasing the capacity of a single fiber using the C-band. The combination of higher order modulation, flex grid channel spacing, higher symbol rates and super channels has increased the spectral efficiency to deliver 32 Tbit/s per single fiber using the standard […]

Optical Networks for the Next Decade

Tuesday, 19 March 2019 Sponsors: ON2020

The volume of user traffic on carrier networks is growing at between 20% and 40% per year and if this trend continues as expected then optical transport networks will become overstretched without a significant increase in capacity beyond that currently planned by operators. The solution to this problem is likely to include a mix of […]

The Programmable Switch Era Is Here… At Last!

7th September 2018

Twenty years after the first network processors were launched, we are now moving toward the fully programmable data plane, with network operator virtualization efforts driving that trend. Most physical networking systems are being replaced by virtual network functions (VNFs) running on servers at the core and edge of the network. These servers have general-purpose processors […]
