Carestream Health Assigned Patent
ALEXANDRIA, Va., Feb. 19 -- Carestream Health, Rochester, N.Y., has been assigned a patent (8,113,702) developed by Gilbert Feke, Glastonbury, Conn., for a "variable condenser for delivery of illumination including recursively nested circle to-line fiber optic converter cable."The abstract of the patent published by the U.S. Patent and Trademark Office states: "A variable condenser for delivery of illumination, including a recursively nested circle-to-line fiber optic shape-converting cable and a focusable input lens system. At the input of the fiber optic cable, sets of individual optical fibers comprise successively smaller annuli recursively nested about a common center. At the output of the fiber optic cable, the sets of individual optical fibers comprise pairs of line segments recursively nested about the line midpoint, whereby the nesting level of the pairs of line segments has an exact or an approximate correspondence to the nesting level of the annuli. The output may be split into a plurality of lines, whereby the sets of individual optical fibers are distributed among the plurality of lines. The input lens system has a single adjustable focus means to vary the radius of an illumination spot incident upon the input of the fiber optic cable circle input."
PacketFront intros ASR6000 gigabit-to-the-home platform
Swedish vendor PacketFront has a new addition to its advanced service router (ASR) product family, the ASR6000. The broadband router uses a hybrid ASIC and network processor design to deliver improved functionality for controlling bandwidth consumption and traffic quality of services in the access layer, the company claims.The ASR6000 supports 100-Mbps and 1-Gbps speeds over both copper and fiber access ports, as well as providing full wirespeed IPv4 and IPv6 routing and switching. The compact form factor makes the ASR6000 suitable for local deployments in buildings and high-density central-office installations. The new features reduce the operational costs for running broadband networks, as well as improving the quality of the delivered services, says PacketFront."The two main challenges facing broadband operators today are consumers’ increasing demands for bandwidth and the need for a secure IPv6 Internet access. The ASR6000 delivers both of these," says Fredrik Nyman, access product manager at PacketFront. "IPv6 security is at the top of the agenda for many broadband networks. The ASR6000 native dual-stack deployment makes it possible to proceed without this issue becoming an obstacle."The new, script-based service control framework means that each ASR6000 can independently use RADIUS or DHCP servers to authenticate and to supply services to end-user clients. This creates a very cost-effective approach for service control and network management.The ASR6000 also contains features to simplify network operations. For example, remote packet capture and quality inspection of TV broadcasts make it possible to analyze each customer’s experience of network services and shorten troubleshooting time. Furthermore, the ASR6000 provides improved queuing and scheduling with thousands of virtual queues, true ingress and egress traffic shaping, and fair queuing to ensure the best possible customer experience when using the Internet.The ASR6000 has been selected by Affärsverken, a utilities company in Karlskrona in the south of Sweden, to upgrade approximately 7000 ports in the local municipality’s network, which serves official organizations including schools and local government offices."We selected the ASR6000 because of its ability to deliver customized services for the municipality network," said Jan Lindqvist, manager business area broadband from Affärsverken. "In particular, the ASR6000 feature for authenticating and enabling different services for different end-users such as teachers and students in the school part of the network were key features in selecting the platform."The ASR6000 provides an efficient mix of municipality control over services and network operator control over infrastructure that is unique in the gigabit-to-the-home (GTTH) market, PacketFront claims.
AppliedMicro ships 100G OTN transponder/muxponder chip
AppliedMicro says it has moved to general production availability of the TPO/TPOT404 transponder/muxponder and PQ60T 10/40G mapper/framer PHY, a combination AppliedMicro claims is the industry's first standard 100-Gbps transponder/muxponder offering for Optical Transport Network (OTN) and data centers.The integrated framer/mapper PHY and SoftSilicon design has been developed by AppliedMicro’s TPACK subsdiary (see "AppliedMicro to acquire FPGA IP company TPACK to pursue OTN biz"). The SoftSilicon approach uses FPGAs (provided, at least at the time of the acquistion, by Altera) and TPACK IP to create a device that combines the flexibility and economics of FPGAs with the ease of use of ASSPs.Having introduced the part one year ago (see "AppliedMicro unveils standard 100G OTN muxponder"), the company says its designs have now passed all interoperability tests and are reaching initial stages of deployment in 100G carrier and data center networks. Lars Pedersen, CTO of AppliedMicro TPACK, told Lightwave that the company has customers for the chipset, but declined to identify them or provide a total number.AppliedMicro says the 100G device is capable of multiplexing any combination of 10G and 40G client signals into a 100G OTN signal (i.e., OTU4).  Signals supported include 10G and 40G Ethernet and legacy OC-192/OC-768 SONET/SDH, as well as 8G and 10G Fibre Channel. As a result, the device can carry both data and storage traffic efficiently and can be used for file and backup synchronization between large data centers. It also interoperates with all major forward error correction (FEC) schemes in long-haul optical network architectures.AppliedMicro has also created a common Application Programming Interface (API) for the TPO/TPOT404 and PQ60T to enable efficient integration and maintenance efforts for equipment vendors.In addition, Pedersen said that some customers are using the TPO404 on a standalone basis for to support the transmission of 100 Gigabit Ethernet streams directly over OTU4 networks."Our recent survey of carriers shows that new deployments of 100G technology appear unstoppable. Operators will deploy higher speed wavelengths to achieve the lowest cost per bit for the transport of SONET/SDH, OTN, and Ethernet network traffic," said Andrew Schmitt, directing analyst, optical, for Infonetics Research. "Solutions like AppliedMicro's transponder/muxponder designs are well positioned for the rapid deployments of 100G OTN technology for long-haul applications."Reference designs and API for the 100G transponder/muxponder offering are now available.
