Hamamatsu completes Beijing factory
Hamamatsu Photonics has announced the completion of a new building at its Beijing Hamamatsu Photon Techniques subsidiary to expand its manufacturing capacity, as well as its and research and development activities in China. Operations at the new building located at the Langfang Factory, have already begun.
Telecom Austria hails successful field trial
Telekom Austria has successfully tested the 400G high-speed technology between Zagreb in Croatia and Ljubljana in Slovenia. This field trial focused on testing the 400 Gbit/s technology on existing fibre optic cables.
New laser design promises faster fibre optic broadband
Researchers at Caltech have developed a new semiconductor laser that could transmit data at higher speeds along an optical fibre. The work could pave the way for faster broadband internet and other optical fibre communications.
The new laser design has a much higher spectral purity than the semiconductor distributed-feedback (DFB) laser that is at the heart of today’s fibre optic communications. The new laser has more than 10 times the linewidth improvement compared to commercial semiconductor lasers, the researchers state, with the possibility of further increase in coherence.
Free space optics to speed stock exchange
Data transmitted between the data centres of the New York Stock Exchange (NYSE) and Nasdaq will soon be made by a laser network, which is due to be switched on in March.
Chicago-based Anova, a low-latency network and optical engineering firm, has set up the laser network that covers the 35 miles between the data centres of the NYSE in Mahwah, New Jersey and those of Nasdaq in Carteret, NJ.
Coriant and Juniper collaborate to increase network capacity
Coriant, a supplier of metro-to-core transport solutions, has announced the latest progress in its collaboration with Juniper Networks to create an integrated packet transport network (IPTN).
Recent joint R&D between the two networking innovators resulted in the first multi-vendor line side interworking between router and DWDM system suitable for long haul (LH) transmission.
Fibre broadband company's advert breached code
A fibre broadband provider in the UK has been reprimanded by the country's Advertising Standards Authority (ASA) for the use of misleading language in advertisements.
Rural FTTC users in UK 'might as well be on dial-up'
Poor broadband provision in the UK is damaging children's education in rural areas, according to a survey.
Figures from insurance company NFU Mutual, which surveyed 1,600 parents, suggest that a third of those with internet access in rural areas believe the provision is too slow.
Guidance for network disaster damage
Natural and human-caused disasters can damage or destroy data and communications networks – and several presentations at the 2014 OFC Conference and Exposition next week in San Francisco will present information on strategies that can mitigate the impacts.
Disasters such as earthquakes, tornadoes, or even terrorist attacks, can damage data centres and the communication links between them, causing massive losses in data and costly disruptions.
IBM sets data transfer record
Researchers at IBM have set a new record for data transmission over a multimode optical fibre, a type of cable that is typically used to connect nearby computers within a single building or on a campus. The achievement demonstrated that the standard, existing technology for sending data over short distances should be able to meet the growing needs of servers, data centers and supercomputers.
Photonic devices built via standard CMOS process
Engineers have demonstrated that low power photonic devices can be fabricated using standard chip-making processes. The work was part of the U.S. Defense Advanced Research Projects Agency’s Photonically Optimised Embedded Microprocessors (POEM) project.
They have achieved what the researchers say is a major milestone in photonic technology. The work will be presented at this year’s Optical Fiber Communication (OFC) Conference and Exposition, being held from 9 to 13 March in San Francisco.
Drop technologies 'could increase fibre deployment'
Simple drop technologies for easy, fast and cost-effective fibre-to-the-premise (FTTP) installations could, if more widely adopted, increase the rate of fibre deployment in Europe, according to the head of Fujikura's fibre optic division.
Fujikura says it has fine-tuned a high-performance low-friction cable for duct applications which can be pushed from the basement of the building to the individual subscriber. The low friction coating and optimised mechanical design minimises the physical resistance of this process. Field installable terminations allow minimal cable inventory.
