TERAWAVE INTRODUCES HIGH DENSITY PON-BASED LAN-SWITCH MODULE.
Terawave Communications, Inc., a provider of high-speed data-services over Passive Optical Networks (PONs) has introduced a low cost, high density PON-based LAN-Switch Module (LSM LSM Linux Software Map

There are no optical repeaters or other active devices in a PON, hence the name "passive. Access Module architecture, the new LSM plug-ins can provide up to nine 10/100 Mbps 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. service ports per TW-300 chassis which is unparallel in the industry today.
VLANs form an important element of any IT group's administrative strategy. In today's highly mobile computing environment, employees are often required to connect into their company's network from remote sites. Also, cross-functional teaming requires many employees to be part of diverse departmental sub-networks at different moments in time. Terawave's VLAN implementations offer a solution for just this problem. By using Terawave's TW-300 LAN-Switch Module (LSM), tracking and ensuring zero downtime for a worker's connectivity is no longer a logistical nightmare for the IT department. The TW-300 LSMs can enable tracking of workstation movements without requiring manual reconfiguration of IP addresses, and also allow creation of closed user groups and broadcast domains.
Based on the IEEE's 802.1Q standard, Terawave's LSM is an elegant application of the TeraPON technology suite for VLAN scenarios. By marrying the bandwidth flexibility offered by Terawave's SALSA salsa (säl`sə, sôl`–), American popular music developed largely in New York City during the 1970s; its name is derived from the Spanish word for hot sauce. technology with VLAN functionality, the PON- based LSM solution can offer superior QoS performance and increased service options for the Service Provider. "The inherent burstiness of LAN traffic allows us to exploit statistical multiplexing across the entire GigaPON. Our SALSA technology ensures that a particular VLAN port has sufficient instantaneous bandwidth when required," states Don Stalter, vice president of marketing at Terawave Communications. The PON-based LSM allows VLAN definition by port groups and MAC addresses, and also supports the 802.1Q fully tagged frame formats, which enable port membership in multiple overlapping VLANs.
In addition, the PON-based LSM supports traffic filtering based on source and destination MAC addresses, using static and dynamic network address learning rules. This allows the Service Provider to create sophisticated Service Level Agreements (SLAs) in which traffic from certain subscribers can be preferentially treated over others. This enables service differentiation for performance based Quality of Service (QoS), as well as SLA (1) (StereoLithography Apparatus) See 3D printing.
(2) (Service Level Agreement) A contract between the provider and the user that specifies the level of service expected during its term. policy based rules.
Finally, Terawave's PON-based LSM brings extremely low-cost, high-speed Internet access to the consumer by allowing LAN extension across local and wide-area networks. Terawave's LSM opens the road to commoditizing bandwidth hungry applications such as Internet based video services by eliminating the current bottlenecks associated with DSL DSL

It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary technology. By using the ubiquitous LAN interface, specialized DSL modems are also eliminated.
About Terawave Communications, Inc.
Founded in December 1998, Terawave Communications develops next generation Passive Optical Network (PON) and Dense Wave Division Multiplexing (spelling) wave division multiplexing - A common misnomer for wavelength division multiplexing. (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.

Terawave's management team combines talent from such industries as telecommunications, optical networking, high-speed electronics, and ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. design. With $60 million in funding, the company currently employs more than 150 professionals at two facilities in Hayward and an ASIC design center in Petaluma, California.
Leveraging advances in silicon, optics and software, Terawave developed a product family that provides the scalability, flexibility and economics that service providers require to deliver optical services over ATM, IP and TDM network infrastructures. Terawave has created world-class competency in application specific integrated circuit (ASIC), optical system and component design, IP and ATM technologies, SDH/SONET, as well as network management systems.
