Huawei takes broadband access triple crown
SEPTEMBER 4, 2009 - According to Dittberner’s “DSL, FTTH and FTTB/LAN Shipment Analysis,” Huawei was the leader in 2Q09 DSL, PON, and FTTB/LAN port shipments, the first time one vendor has led all three market categories. Huawei took PON leadership from Mitsubishi, which has led that category for the past three years; this is the first time a Japanese vendor has not been the PON leader since Japan launched its FTTH campaign in 2004.The PON market includes ONTs, OLTs, and ONUs. Quarterly PON shipments were up 17 % quarter on quarter, just shy of the record quarterly shipment of 3 million ports. Three of the top six vendors were Chinese, reflecting the rapid growth of that market. This market’s growth is also causing GEPON to take market share away from GPON and BPON as well.It is the growth of China’s FTTB/LAN market that is propelling Huawei into the lead in the PON market. Most of the PON deployments in China use GEPON and ONUs. The FTTB/LAN market more than doubled in the second quarter, and Dittberner expects it to set more records in the next few quarters. Dittberner’s Broadband Study is an ongoing market research service updated quarterly, designed to track the BBxDSL and BBFTTX vendors and their potential. The study constitutes business cases, case studies, and market forecast. Dittberner provides users of this service with fully interactive spreadsheets including actual and historical shipments.
Aurora Networks offers five steps toward green optical networks
AUGUST 31, 2009 -- Aurora Networks Inc. (search Lightwave for Aurora Networks) has developed a checklist of what it considers five "must-have" components for cable operators who are pondering "green" optical networks.Aurora points out that, according to the IEEE's Energy Efficient Ethernet Committee, telecommunications network equipment alone accounts for 1 percent of all power consumption in the United States. Also, research from the International Telecommunications Union estimates that the global information and communications technology (ICT) industry accounts for about 3 percent of global carbon dioxide emissions. These industry statistics, coupled with operator feedback, support the need for a cost-effective transition to environmentally friendly equipment and services, Aurora asserts.To meet the cable industry's need for a cost-effective transition to environmentally friendly equipment and services, Aurora Networks recommends that operators look at the following criteria when choosing a green optical transport architecture:Elimination of RF actives: Cable network architectures that eliminate the need for RF amplifiers in the coaxial plant by pushing fiber deeper realize more than a 70 percent reduction in the number of active devices in the distribution portion of the network. This results in more than a 50 percent drop in power consumption and a significant reduction in maintenance requirements, including truck rolls. Fiber is hundreds of times lower in signal attenuation than coax; thus replacing coax with fiber enables a significantly more efficient network to be built.Cut in operating costs: Building a network with fewer active components greatly decreases overall costs in equipment installation and proactive network maintenance. A network architecture with fewer active components can streamline maintenance requirements and accrue additional green benefits, including lower gas consumption and exhaust emissions that result from fewer truck rolls.Reduction in the number of homes served per node: Traditional HFC architectures typically serve from 500 to 2,000 homes. Operators can reduce the number of homes served per node for greater network granularity. This not only increases bandwidth per subscriber, but also reduces the number of actives in a network, dramatically increasing network reliability and associated service availability. Ultimately, this results in fewer potential failure points between the headend and the customer; and an outage will affect fewer subscribers.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.Element management system: With increasing subscriber reliance on higher-revenue services, high network availability is critical and hence operators need to minimize any network downtime. With the latest advances in digital return technology, element management can now be achieved without the need for high-cost transponders, headend and hub hardware, and expensive software.
NTIA, RUS see strong demand for first round of broadband funding
AUGUST 28, 2009 -- The Commerce Department's National Telecommunications and Information Administration (NTIA; search Lightwave for NTIA) and the Department of Agriculture's Rural Utilities Service (RUS; search Lightwave for Rural Utilities Service) announced today that they received almost 2,200 applications requesting nearly $28 billion in funding for proposed broadband projects reaching all 50 U.S. states and territories and the District of Columbia.This is the first round of American Recovery and Reinvestment Act (ARRA) funding aimed at expanding broadband access and adoption to help bridge the technological divide and create jobs building Internet infrastructure, with $4 billion available through loans, grants, and loan/grant combinations.The ARRA provided a total of $7.2 billion to NTIA and RUS to expand access to and adoption of broadband services. Of that funding, NTIA will utilize $4.7 billion to deploy broadband infrastructure in unserved and underserved areas in the United States, expand public computer center capacity, and encourage sustainable adoption of broadband service. RUS will invest $2.5 billion to facilitate broadband deployment primarily in rural communities. Approximately $2.4 billion from RUS and up to $1.6 billion from NTIA is available in this first grant round.Applications came in from a range of parties including state, local, and tribal governments; nonprofits; industry; anchor institutions, such as libraries, universities, community colleges, and hospitals; public safety organizations; and other entities in rural, suburban, and urban areas."Applicants requested nearly seven times the amount of funding available, which demonstrates the substantial interest in expanding broadband across the Nation," says Lawrence E. Strickling, Assistant Secretary for Communications and Information and Administrator of NTIA. "We will move quickly but carefully to fund the best projects to bring broadband and jobs to more Americans.""The overwhelming response we received underscores the extensive interest in expanding broadband across the country. Rural communities clearly recognize that broadband can expand their economic opportunities and create jobs," says Jonathan Adelstein, Administrator, Rural Utilities Service, USDA. "The Obama Administration's goal is to target funds to serve areas of greatest need. The big demand for loans as well as grants demonstrates that we can leverage private investment with USDA's $2.5 billion to deliver the greatest bang for the taxpayers' buck."A preliminary analysis of applicant-reported data shows that NTIA and RUS received requests for grants and loans totaling nearly $28 billion. When including about $10.5 billion in matching funds committed by the applicants, there are over $38 billion in proposed broadband projects.The applications break down as follows.
