Siemens Announces 10 Gbps PON Breakthrough, 100km Range

Researchers from Siemens Networks demonstrated the ability to transmit data at 10 Gbps error-free over a passive optical access network -- this is four times faster than current GPON technology. The upstream capacity was rated at 2.5 Gbps and the number of subscriber lines per splitter was expanded to 512. Siemens also achieved a 100 kilometer distance between hub and subscribers -- the so-called last mile. Current PONs typically support subscribers within a 20 km radius.



The higher split factor in urban areas allows considerably more subscribers to be connected to a system. It also eliminates the need for the aggregation devices that are now commonly used to collect and distribute data traffic locally. Siemens predicts that in the future, it will be possible to connect subscribers directly to the core network.



In its research for the new PON system, Siemens implemented an optical amplifier, a so-called erbium-doped fiber amplifier (EDFA). Only through use of an EDFA can the extended reach and greater subscriber number be achieved. Optical fibers doped with the element erbium amplify the optical signal of the system and enable longer transmission ranges with higher bandwidth. This device was developed by Siemens in such a way that a purely optical bi-directional amplification is possible. The result: One single compact device can boost optical signals both from the end customer to the exchange and from the exchange to the subscriber.



"We are very confident that we can further develop systems of the next PON generation to reach final market readiness by the year 2009," said Christian Unterberger, President Fixed Networks at Siemens Networks.



In addition to Siemens, the universities of Eindhoven and Essex, the Heinrich-Hertz-Institut Berlin of the Fraunhofer Gesellschaft and leading European network carriers are participating in the Extended Reach PON Systems project.

Poland's Netia selects Alcatel-Lucent for Metro Ethernet

Netia, Poland's largest alternative fixed telecommunications provider, selected Alcatel-Lucent for its country-wide deployment of 10G Metro Ethernet networks. The deployment will include Alcatel-Lucent's 7750 Service Router, 7450 Ethernet Service Switch, 7250 Service Access Switch and the 5620 Service Aware Manager. The network will be used for business services such as Virtual Private LAN Services (VPLS) and IP VPNs, and also will form the base for all future services including triple play.

Alcatel-Lucent Tests WiMAX (Rev-e) in India

The Alcatel-Lucent Research Centre (CARC) in Chennai, India completed a live WiMAX IEEE 802.16e-2005 (Rev-e) field trial using Aircel's licensed spectrum. The trials were conducted using the 2.5GHz band and successfully demonstrated applications in moving conditions such as video streaming, high-speed file downloads, VoIP and Web browsing.

Energy Sciences Network (ESnet) and Global Crossing Announce IPv6 Peering

Global Crossing announced an IPv6 peering agreement with the Energy Sciences Network (ESnet), which provides direct connections to all major Department of Energy (DOE) sites with high performance speeds, as well as fast interconnections to more than 100 other networks.



The new peering agreement will utilize dedicated interconnections to support the exchange of IPv6 traffic between ESnet's users via Global Crossing. IPv6 peering works by exchanging IPv6 routes at the peering session and allowing IPv6 traffic to transit between the two Autonomous Systems. The peering agreement provides ESnet greater carrier diversity and traffic flow on their network.

  • In June 2005, the Office of Management and Budget (OMB) mandated that all federal civilian agencies add IPv6 technology to their network backbones by June 2008. ESnet began utilizing IPv6 in 2000.


  • In August 2006, the Department of Energy's (DOE) Energy Sciences Network (ESnet) and Internet2 announced plans for ESnet4 -- a new network that will initially operate on two dedicated 10 Gbps wavelengths on the new Internet2 nationwide infrastructure and will seamlessly scale by one wavelength per year for the next four to five years. It will deliver production IP capabilities as well as new optical services like point-to-point dynamic circuits. The network will serve large-scale DOE Office of Science projects such as DOE's participation in the Large Hadron Collider at CERN, the Relativistic Heavy Ion Collider at Brookhaven National Lab and several supercomputing centers.

LSI Logic to Acquire SiliconStor

LSI Logic agreed to acquire SiliconStor, a privately held company that provides silicon solutions for enterprise storage networks, for approximately $55 million in cash. SiliconStor provides storage technology focused on the SATA (serial ATA) and SAS (serial attached SCSI) markets. The company is headquartered in Fremont, California, and has approximately 30 employees.



LSI Logic said the acquisition of SiliconStor aligns with its strategy to offer server and storage system customers complete solutions including IC (integrated circuit) controllers, ROC (RAID-on-Chip), expanders, RAID software, and HBAs (host bus adapters) for the fast growing SAS infrastructure.

Calix Supplies FTTP/ADSL2+ for Quebec CLEC

Calix's network access equipment has been selected by Téléphone Guèvremont, a Quebec-based ILEC, and by Maskatel and Téléphone Drummond, CLEC affiliates of Téléphone Guèvremont. The project will utilize Calix C7 multiservice access platforms (MSAPs) to extend new fiber transport facilities to Drummondville, Quebec, overbuilding the current operator. From there, the Calix C7 will deliver voice, Internet access, and eventually IPTV services over short 1.5 Km loops using ADSL2+ and VDSL2 technology. Greenfield locations will be built out using 2.4 Gbps GPON fiber to the premises (FTTP) facilities. Financial terms were not disclosed.

Net Insight Introduces Access/Edge Switch for DTV

Net Insight introduced its Nimbra 360 multiservice access/edge switch, integrating the transport of Digital Terrestrial and Mobile Television services with transfer of highly accurate timing information, thereby eliminating the need for GPS receivers.



The switch offers four built-in multirate SONET/SDH SFP ports and one Gigabit Ethernet port. In addition, up to 16 DVB-ASI ports or other combinations of multiservice access and trunk interfaces are available using the two slots for plug-in modules.



Net Insight said its built-in GbE interface and Ethernet multicast features make the solution very suitable for IPTV distribution or WiFi/WiMAX aggregation. The same platform can also be used for mobile TV whether distributed over IP or ASI MPEG.



DTT and Mobile TV often require a single frequency network (SFN) where the transmitter stations must be synchronized to send their signals at exactly the same time. Nimbra 360 has a time transfer capability that allows highly accurate distribution of real time over the same network that carries the video signals. http://www.netinsight.net

BT Selects KPMG Executive as Next Chairman

SIRIUS and XM to Merge -- 1 Million Satellite Radio Subscribers

XM Satellite Radio and SIRIUS Satellite Radio agreed to an all-stock merger of equals with a combined enterprise value of approximately $13 billion, which includes net debt of approximately $1.6 billion.



The combination creates a nationwide satellite radio provider with combined 2006 revenues of approximately $1.5 billion and approximately 14 million combined subscribers. Mel Karmazin, currently CEO of SIRIUS, will become CEO of the combined company and Gary Parsons, currently Chairman of XM, will become Chairman of the combined company.



The companies cited several reasons for the merger, including synergies for content programming. They also hope to improve on products such as real-time traffic and rear-seat video and introduce new ones such as advanced data services including enhanced traffic, weather and infotainment offerings.



In regard to potential anti-trust concerns, the companies said that in addition to existing competition from free "over-the-air" AM and FM radio as well as iPods and mobile phone streaming, satellite radio will face new challenges from the rapid growth of HD Radio, Internet radio and next generation wireless technologies.
