Anritsu and Lucent Technologies Use OC-48 to Demonstrate Fast Link Between Enterprise Local Area Network Switches.Business Editors/High-Tech Writers NetWorld Interop 2000 RICHARDSON, Texas--(BUSINESS WIRE)--April 27, 2000 Provides Metropolitan Area Network (MAN) Backbone Extension at 2.5 Gbps Anritsu today announced successful interoperability testing of their MultiFlow 5000 multilayer switches See layer 3 switch. with Lucent Technologies' WaveStar 400G WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. (wave division multiplexing (spelling) wave division multiplexing - A common misnomer for wavelength division multiplexing. ) products, more than doubling the voice and data transmission speeds previously attainable between enterprise local area network (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. ) switches over local area network (LAN) and metropolitan area network (MAN) links. Anritsu's ONE(tm) (Optical Network Extension) technology, introduced last year, has allowed enterprises and carriers to carry 2.5 Gbps network traffic up to 80 km between switches over dedicated fiber links. Today's compatibility announcement lets enterprises and MAN/WAN service providers enjoy that same speed with the added distance, more efficient fiber utilization, and reliability of WDM technology. "Anritsu's unique OC-48 SONET offering is a perfect companion for our WaveStar products," said Swee Wong, managing director, Product Marketing, Optical Networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. Group, Lucent Technologies Japan Ltd. "Many enterprises are purchasing WDM equipment or using WDM links from service providers, and the ability to provide long-distance, high-speed backbone fiber links between their facilities will alleviate bandwidth problems they expect to face in 2000 and beyond." Joint testing by Anritsu and Lucent was conducted using two Anritsu MultiFlow 5064 multilayer switches with OC-48 SONET interfaces interconnected via fiber and WDM using Lucent's WaveStar 400G product. Anritsu MultiFlow 5000 products provide Layer 2/3/4 switching for up to 32 Gigabit and 128 Fast Ethernet An earlier name for 100Mbps Ethernet. See 100Base-T. (networking) Fast Ethernet - A version of Ethernet developed in the 1990s(?) which can carry 100 Mbps compared with standard Ethernet's 10 Mbps. It requires upgraded network cards and hubs. ports at full wire speed, and Ethernet interfaces on the Anritsu switches generated LAN data for these WDM compatibility tests. This new WDM compatibility now allows users to choose between employing dedicated dark fiber OC-48 links up to 80 km, or shared OC-48 WDM links at distances limited only by the scope of their WDM network. The Anritsu ONE technology is uniquely suited to extending enterprise backbone networks because it supports all types of Ethernet traffic, including IPX (Internetwork Packet EXchange) The network layer protocol in the NetWare operating system. Similar to the IP layer in TCP/IP, it contains a network address and allows messages to be routed to a different network or subnet. and non-routable traffic, unlike SONET interfaces on other LAN switches and routers that are limited to IP traffic. It also transports industry standard Layer 2 802.1d protocols for VLANs and priority (formerly 802.1Q and 802.1p) that are essential to backbone network operation. Since many medium and larger enterprises already have work group or department level switches with Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. uplinks, OC-48 provides the speed needed to avoid bottlenecks in the backbone network. Additional WAN connectivity in MultiFlow 5000 products is provided through OC-3 ATM and V.35 DS-1 interfaces. "This capability offers a world of value to customers requiring greater-than-gigabit speed over extended distances," says Jack Landau lan·dau n. 1.

"WDM capability greatly increases the benefits of our unique OC-48 SONET interfaces by meeting our customers' needs for interconnecting their facilities at the highest possible speed and efficiency over MAN and WAN links." Anritsu will be exhibiting at the upcoming NetWorld+Interop show, Booth 1132 in the North Hall, at the Las Vegas Convention Center The Las Vegas Convention Center is owned and operated by the Las Vegas Convention and Visitors Authority and is located in Clark County, Nevada. It is one of the largest Convention centers in the world. At the end of 2004, the center had 3. , May 9-11, 2000.
