BelWu Completes Transponder-less IP Network Upgrade to 10 Gbps with Menara Networks' OTN System in a XFP.DALLAS & SUTTGART/ULM, Germany -- BelWu, the Research and Education network of the German state of Baden-Wurttemberg, and Menara Networks, an optical Ethernet transport system specialist, successfully completed an in-service network upgrade over existing DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing infrastructure of BelWu IP backbone network to 10 Gbps. "Baden-Wurttemberg Extended LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. " scientific network (BelWu), the Research and Education network funded by the state of Baden-Wurttemberg connecting more than 32 universities and universities of applied sciences, universities of cooperative education and other colleges, scientific institutions, hospitals, libraries and more than 1500 schools in southwestern Germany, successfully completed its IP core network upgrade to 10 Gbps based on Menara Networks award winning OTN OTN Oracle Technology Network OTN Optical Transport Network (Cienna) OTN On The Net OTN Open Transport Network (Apple) OTN Oncology Therapeutics Network OTN On That Note OTN Optical Network Terminal System in an XFP XFP 10 Gigabit Small Form Factor Pluggable Module XFP Extra-Fine-Pitch XFP Ten Gigabit Small Form Factor Pluggable module. The upgrade consisted of populating Cisco GSR See Gigabit Switch Router. 12000 series routers with Menara's OTN XFPs and connecting the routers over a wide area network utilizing the existing optical infrastructure. Menara's 100% MSA (Metropolitan Service Area) An urban area with at least 50,000 people plus surrounding counties. There are 306 MSAs and 428 RSAs (rural service areas) in the U.S. MSAs and RSAs are used to allocate cellular licenses. compliant XFP transceivers transparently mapped the native 10 GE LAN PHY See physical layer and physical. signal from the Cisco GSR 12000 series router into an ITU-T See ITU. ITU-T - International Telecommunications Union G.709 compliant OTN frame and performed all necessary forward error correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it. and OAM (Operations Administration Maintenance) Refers to managing and maintaining a network or network device. The P in "OAM&P" adds "provisioning" to the list, which is a telephone company term for setting up a service. processing, thus avoiding the deployment of costly DWDM transponders. No modifications to the Cisco 12000 series routers or the existing optical physical network were required for the upgrade. BelWu also deployed Menara's "Link Checker" feature, which allows BelWu to continuously monitor channel Forward Error Correction margin statistics in real-time via the Cisco IOS CLI interface for assured network high availability and SLA compliance. "Menara's OTN system in XFP modules allowed us to seamlessly upgrade our IP backbone to 10 Gbps without having to deploy and maintain DWDM transponders," noted Prof Dr. Hans Peter Grossmann, Director of the Communication and Information Center at Ulm University and head of BelWu Technical Committee. "Our network connects several state-of-the-art super computing and HPC facilities and we have very stringent performance and availability requirements. Having OTN based Forward Error Correction capabilities and BER (1) (Basic Encoding Rules) A set of encoding rules for ASN.1 notation, which is a method for defining data structures. See ASN.1.

See BERT. 1. monitoring in real-time is just as crucial to our operations as the significant savings from this architecture; a first among European research networks European Research Networks is a trend in scientific research at European Union level that has been widely promoted through Framework Programmes for Research and Technological Development since 1984 to strengthen European Research Area. . This upgrade is part of our on-going efforts to maintain a cutting-edge, high performance research network in the state of Baden-Wurttemberg." "We are pleased to have collaborated with BelWu on this important milestone," said Sri Nathan, Vice President of Business Development of Menara Networks. "This latest deployment of our OTN system in an XFP further demonstrates the viability and efficiency of our solution and underlies its disruptive economics through the elimination of the costly DWDM transponder systems that plague the network. We are also proud to have helped BelWu towards attaining its goal of a greener network by reducing the DWDM optoelectronics power consumption by 75% with out OTN XFP."
