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.
Brazilian regional service provider, Copel Telecom has deployed 200G optical transmission technology from Coriant to scale its fibre optic backbone network in the State of Paraná.
Google is building a new submarine cable system to connect the East coast of the United States with Europe. TE SubCom has been selected to build the Dunant four-fibre pair cable system, which will span more than 6,400km.
Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4,000km fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. The reach improvement shown is 5.6 times that which is possible when using conventional erbium-doped fibre amplifiers.
Vodafone has successfully completed a live network trial in Spain as part of its work with the Telecom Infra Project (TIP), using the Voyager optical ‘white box.’
The goal of the live trial was to showcase the future of applying a disaggregated model to optical networks and to provide more flexibility to handle the real time dynamics using Voyager, combined with a software-defined network (SDN) controller.
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.
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.
The undersea cables used for communications could be used to detect underwater earthquakes according to scientists at the National Physical Laboratory (NPL) and Istituto Nazionale di Ricerca Metrologica (INRiM, Italy), who have developed a new method of using the cables as ‘acoustic sensors.’
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.
TE SubCom has won a contract with Vanuatu-based consortium, Interchange to construct the ICN2 submarine cable that will connect Port Vila, Vanuatu and Luganville, Vanuatu to Honiara, Solomon Islands.
As data demand ramps ever higher, researchers are looking to innovative amplifier designs to help transport a broader light spectrum through optical fibres, finds Andy Extance
Duncan Ellis shares his views about the increased focus on automation from network operators, and how the physical layer has so far stubbornly resisted the move
Switching off copper networks where fibre has been deployed is the end game, so why are so few operators doing it, wonders Pauline Rigby
With demand for fibre to the premises increasing, Keely Portway looks at the role training plays in ensuring installation skills remain available to meet this growing demand
