Verizon Communications has named Hans E. Vestberg, executive vice president and president of global networks and chief technology officer. Vestberg will succeed Lowell C. McAdam as CEO, effective 1 August 2018. McAdam – who was named CEO on August 1, 2011, and chairman on January 1, 2012 – will serve as executive chairman of the board through his retirement from the company at the end of the year, after which he will become non-executive chairman.
When Hurricane Sandy battered the eastern seaboard of the United States in 2012, a storm surge caused catastrophic flooding of Verizon’s central office (CO) in Broad Street, Manhattan. Miles of underground copper cables were ruined by the water. Even worse, paper insulation in the wiring sucked water deeper into the network through capillary action, destroying cables in otherwise dry areas. Verizon found that it was too difficult, expensive and time-consuming to rescue the existing copper network, so decided to rewire with optical fibre cables instead.
Philippines cable operator, SKY Cable is using end-to-end systems from Calix to drive its expansive network transformation to fibre.
The plan is to transform its existing, traditional cable network into an ‘always-on’ software defined network, serving the greater metropolitan areas of Manila and Rizal, as well as Cavite and Laguna. The operator will also deploy AXOS DPx, and Calix WiFi enabled GigaHubs at subscribers’ homes and businesses. The new network will be built end-to-end on Calix AXOS.
Verizon will begin its large-scale NG-PON2 deployments during the first quarter of this year, for which the US operator has confirmed Calix as a main supplier partner.
Starting the transformation in Tampa, Florida – with plans to expand into other markets – Verizon will deploy a single access network for residential, business, and mobile services in what it says is an ‘industry-first’ use of NG-PON2 technology.
Verizon has completed a successful field trial delivering live 400Gb/s Ethernet traffic on a single wavelength between MPLS Core routers over its packet-optical network.
The trial demonstrated the interoperability between equipment from two different suppliers – Ciena and Juniper – alongside the capability to quadruple the typical capacity carried on one wavelength.
Verizon has deployed Sedona Systems’ NetFusion network intelligence and automation system across its entire network. The move was designed to facilitate a more complete understanding of the relationships and dependencies between the IP and optical network layers, forming an accurate network database for analytics and automation.
Calix announced that it is the first vendor to demonstrate ITU standards-based channel bonding for NG-PON2, which combines multiple 10Gb/s channels to create a single channel with throughput of up to 40Gb/s.
Channel bonding allows operators to deliver more bandwidth than a single channel can support. This technique is used to boost capacity in DSL and G.fast systems by combining the capacity from several copper cables into a single logical channel. In the case of NG-PON2, the channels are wavelengths running over the same physical fibre.
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
