Network core flexibility will become just as important as capacity for future networks, and coherent solutions could be key to accommodating changing traffic flows, argues Eugene Park
In response to growing demand for more data capacity, the DE-CIX internet exchange is now offering 400GbE access technology.
The Engineering and Physical Sciences Research Council (EPSRC) has committed a £4.9 million grant to fund a national research facility to support UK researchers in creating communications networks for the future.
A group of researchers from Universitat Politècnica de Catalunya in Barcelona, alongside Huawei, have re-tooled an artificial intelligence technique to improve efficiency in optical transport networks (OTNs).
Ciena has revealed its latest range of WaveLogic technology products, which includes a single-wavelength 800G solution.
Researchers at Royal Melbourne Institute of Technology (RMIT) in Australia have developed new fibre optic technology that can harness twisted light beams to more quickly carry and process data.
ADVA Optical Networking is developing a commercial device to support the Telecom Infra Project's (TIP) Disaggregated Cell Site Gateway (DCSG) group.
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.
A central European cable and satellite operator has successfully completed the testing of a hybrid last-mile broadband solution combining Iskratel’s GPON technology and Teleste’s DOCSIS-based mini-CMTS.
Ciena’s GeoMesh Extreme open network architecture with high-density 100G transponders has been selected to enhance two submarine networks in the Caucasus and Latin America regions.
As sole owner of the Black Sea submarine cable, Caucasus Online provides critical services in regional communications, acting as a major gateway for internet traffic from Europe to South Caucasus and the Caspian region.

Keely Portway takes a look at the next generation of bend-improved fibres, and how they can be best used to future-proof networks
Ray O’Connor argues that wireless and fibre should be considered complementary, rather than in competition
Mattias Fridström and Parthiban Kandappan put software-driven, real-time optical layer performance awareness to the test
The right combination of training and tools will help to future-proof fibre reliability, says Jay Tourigny
Creating an invisible network is the next step in connectivity, so it is important to put quality, rather than speed at the heart of broadband experience, says Robin Mersh
