Transmode is enhancing its packet transport offerings as operators look for greater traffic and service efficiencies in the metro. Three new technologies are being added to create what the Swedish system vendor calls Native Packet Optical 2.0 (NPO2.0). Already launched is Multiprotocol Label Switching – Transport Profile (MPLS-TP), while the Metro Ethernet Forum’s (MEF) latest […]
ADVA Optical Networking along with IBM and Marist College have demonstrated software-defined networking’s (SDN) ability to virtualise the physical network linking data centres. SDN is already used within the data centre but extending the technology across operators’ networks is more challenging. Equipment used within the data centre is limited to a few types […]
Coriant is working with operators to develop a software-defined networking (SDN) test bed to demonstrate IP-over-DWDM using the system vendor’s Intelligent Optical Control framework. The test bed, based on IP routers and SDN controllers, will demonstrate packet networking using the OpenFlow standard and other mechanisms. The SDN controllers will also connect to the […]
Deutsche Telekom plans to turbo charge its national broadband infrastructure with a speed upgrade for its mobile LTE network and the widespread roll out of vectoring in the fixed network. “We’re strengthening our position as the leading network provider for our customers. No other telecommunications company invests as much as Deutsche Telekom,” claimed […]
Systems vendor Huawei has acquired Caliopa, a four-year-old silicon photonics start-up that spun out of the photonics research group at Ghent University and Imec in Belgium. Caliopa is developing optical transceivers based on silicon photonics that can be manufactured using standard microelectronic CMOS manufacturing processes. Using silicon photonics enables transceivers that are more […]
In what it is calling “an important first step in restructuring our company”, optical components and subsystems vendor Oclaro has sold its Oclaro Switzerland GmbH subsidiary and associated laser diodes business to II-VI Inc. in a transaction valued at $115 million (€86 million). In addition, II-VI has paid a further $5 million for […]
The development of 400 Gigabit Ethernet has officially started with the launch of the 400 Gb/s Ethernet Study Group at the IEEE Standards Association. The group held its first meeting in Victoria, Canada, earlier this month. The process really got underway with the release of the IEEE 802.3 Ethernet Bandwidth Assessment report in August 2012, […]
The UK incumbent BT says it will begin to offer 300Mbps broadband service in the areas where it has rolled out fibre-to-the-premises (FTTP) networks. The service comes with a 20 Mbps upload speed and costs £50 per month plus BT line rental, which is currently £15.45 per month. Only a select few will be able […]
Over the past year, national research and education networks (NRENs) around the world have been upgraded their networks to 100-Gbps transmission speeds. But collaborative work has been hampered by the lack of high-speed connections between individual networks. Now a group of six networks has joined forces to set up an intercontinental 100-Gbps connection. During the […]
Global sales of AOCs won’t match last year’s stellar growth of 65 percent, but will continue to expand at a respectable rate of 30 percent this year, according to the latest report from market analysts at LightCounting. LightCounting also predicts that the market for active optical cables (AOCs) will reach $150 million in 2013. AOCs […]
Finisar and u²t Photonics have gained exclusive use of indium phosphide-based modulator technology developed at the Fraunhofer Heinrich-Hertz-Institute (HHI).The two companies will also jointly develop the technology for transmitter designs at 100G and beyond. Finisar and u²t immediately gain polarisation multiplexed I-Q modulator technology for 100Gbps coherent applications following the agreement. Meanwhile, u²t has also acquired the […]
Telecom Austria subsidiary A1 has tested out a new technology from Alcatel-Lucent that aims to provide optical fibre speeds over the copper telephone network. In a field trial on installed lines, the broadband operator achieved data rates of over 1 Gbps over a distance of 70m. G.fast is a new standard, still several years from […]
Nearly all the major operators are evaluating software-defined networking (SDN) or plan to do so within the next three years, according to a survey conducted by market research firm Infonetics Research. Industry interest in SDN appears justified, with 86 percent of the operators interviewed confident they will deploy the technology and network functions virtualisation (NFV), […]
Researchers at Bell Labs, the R&D arm of Alcatel-Lucent, say they have successfully transmitted data at 31Tbps over a distance of 7,200km, claiming a new world record for data transmission over a single optical fibre. This capacity exceeds that of the most advanced commercial undersea cables today by a factor of three, the company claims.The […]
Ciena, working with partners from the research and education community, is building a network to enable the development of software-defined networking (SDN) in the wide area network (WAN). The motivation in setting up the test bed network is to boost carrier confidence in SDN while accelerating technology development. “The goal is to leap to the […]
US carrier Verizon has demonstrated 200Gbps optical transmission over 260 miles of its optical network linking New York and Boston. The trial used equipment from system vendor Ciena that included the vendor’s WaveLogic3 coherent optical processor and test software to implement higher order modulation based on 16-QAM (quadrature amplitude modulation). The 16-QAM signal was carried […]
Two mobile backhaul chips for the LTE cellular standard have been announced based on very different architectures. PMC-Sierra has detailed the WinPath4, a programmable chip, while Broadcom has announced the StrataXGS BCM56450, a configurable Ethernet chip. Being programmable, the WinPath4 is flexible and can be customised whereas the BCM56450, with its greater throughput of 100Gbps, […]
A team of U.S. researchers funded by the Defense Advanced Research Projects Agency (DARPA) and led by Honeywell International have developed hollow core optical fiber capable of transmitting high-intensity light beams with much lower latency than standard silica optical fibres. The intensity of light that propagates through glass optical fiber is fundamentally limited by the […]
Optical switch developer Calient Technologies, Inc. says it has raised a $27 million round of venture financing from a combination of existing and new investors. The company also named Jag Setlur, a 20-year finance professional, as its chief financial officer (CFO). Founded in 1999, Calient developed an all-optical switching system based on tiny tilting mirrors etched […]
Cisco has been chosen by the Brazilian Network Information Center (NIC.br) to upgrade the PTT.br Internet exchange with IP/DWDM and 100G technologies. The upgrade also includes deployment of the Cisco ASR 9000 Series router for highly resilient and redundant IP connectivity and robust support for IPv6. The upgrade also covers the PTT.br fibre-optic infrastructure between […]
