Aurora Networks Identifies Critical Components for Green Optical Networks

By Nathesh, TMCnet Contributor


Aurora Networks, a pure-play optical transport solution provider, said it has identified five “must-have” components for green optical networks. Aurora says it intends to help cable operators to assess the environmental and financial benefits of having green optical networks.
 
It is been estimated that the telecommunications network equipment alone accounts for one percent of total power consumption in the U.S. and the global ICT industry is responsible for about three percent of global carbon dioxide emissions. In order reduce its carbon footprint it is imperative for the industry to opt for affordable and environmentally-friendly equipment and services.
 
Cable operators can implement the most effective and green optical transport solutions to deliver today’s subscriber-demanded services to reduce energy usage and other environmental impacts.
 
Aurora says that the cable industry is working on many innovative strategies to reduce environmental impact while at the same time decrease operational costs. Aurora is working with many operators around the globe to implement green solutions as the company sees an opportunity to share their field knowledge so that the entire industry can benefit.
 
Aurora recommends these five criteria for cable operators while choosing green optical transport architecture:
  •  
    Elimination of RF actives – Architectures that remove the need for RF amplifiers in the coaxial plant by pushing the fiber deeper can take in 70 percent reduction in the number of active devices in the distribution portion of the network which in results in 50 percent less power consumption and less maintenance.
  • Cut in operating costs – Building a network architecture with fewer active components brings down the equipment installation and maintenance costs and can streamline maintenance requirements and ensue additional green benefits.
  • Reduction in the number of homes served per node – By reducing the number of homes served per node operators can see greater network granularity and increase the bandwidth amount per subscriber, and also reduce the number of actives in a network, dramatically increasing network reliability and associated service availability.
  • Future-proof technology – Digitized return technology supports the transport of legacy upstream services and DOCSIS 3.0 without distance limitations to ensure that any green network upgrades also contain the components for a future-proof network.
Aurora has stated that using these five criteria operators can convert their existing network into green network and achieve significant cost savings. The company claims that its own Fiber Deep solution meets all these five criteria.
 
Aurora recently launched its NC2000 optical node and announced that it has increased the fiber capacity and CPE density, expanded the management options.
