Sycamore Networks expands capacity, services and switching capabilities of SN 3000 optical access switch

May 11, 2001
May 10, 2001--Sycamore Networks, a provider of intelligent optical networking, introduced an expanded feature set for the SN 3000 Optical Access Switch, enabling service providers to immediately improve operational efficiencies of their metro networks.

Sycamore Networks (NASDAQ: SCMR), a provider of intelligent optical networking, introduced an expanded feature set for the SN 3000 Optical Access Switch, enabling service providers to immediately improve operational efficiencies of their metro networks, as well as expand the services they can offer from the edge of the public network. The SN 3000 now combines the highest connection density with the widest service range of any intelligent optical access switch currently available.

New features include a 4 x OC-48/STM-16 service module, enhanced restoration and protection options that offer rapid, end-to-end restoration for ring and mesh networks, and the general availability of a 1 x OC- 192/STM-64 service module. The SN3000 Optical Access Switch combines service access, transport and switching in a single platform to provide a cost-effective on-ramp to the Intelligent Optical Network.

Sycamore's SN 3000 allows 360networks to extend the benefits of the optical mesh from the core to the edge of the optical network, according to Stephen Baker, chief technology officer of 360networks. "This intelligent optical access switch will allow us to enhance the end-to-end delivery of high-speed, customized services such as fixed point-to-point, optical virtual private networks and rate adaptive Gigabit Ethernet."

Unlike other optical access switches that provide carriers with only one or two OC-48/STM-16 connections into the core network, the SN 3000 now allows service providers to create more efficient metro architectures and easily integrate ring-based architectures into a mesh core. Offering three times the connection density of any other product in its class, the SN 3000 is capable of supporting up to 14 OC-48/STM-16 connections in a single 19-inch chassis, enabling service providers to provide the complete range of OC- n/STM-n and rate adaptive Gigabit Ethernet services in a small footprint.

Sycamore's SN 3000 Optical Access Switch can reduce the amount of time and resources required to deploy optical services in the metro, allowing service providers to realize faster returns on investments of metro service providers.

With the addition of two new restoration enhancements, 1+1 linear Automatic Protection Switching (APS)/Multiplex Section Protection (MSP) and Unidirectional Path Switched Ring (UPSR)/SubNetwork Connection Protection (SNCP), protection for access rings, the SN 3000 supports full protection at, or exceeding, traditional SONET/SDH restoration times (50- milliseconds and below) across a wide variety of network topologies. This new functionality, delivered as an enhancement to Sycamore's BroadLeaf networking software and in combination with existing restoration options on the SN 3000, enables service providers to offer a broad range of services with different restoration options to address a variety of customer requirements. In addition, the enhancements provide a seamless integration into traditional networks and are compatible with any APS/MSP compliant device while it fully participates and supports UPSR/SNCP for access rings.

BroadLeaf, a blend of open industry standard signaling and routing protocols and innovative soft optics, provides the SN 3000 with an advanced, intelligent software platform that makes dynamic, end-to-end provisioning and restoration possible.

The SN 3000 is a high-performance optical access switch designed to aggregate, groom, and switch services in the metro access portions of intelligent optical networks and efficiently bridge traffic through the core of the public network. The SN 3000 combines the functionality of today's SONET/SDH Add Drop Multiplexers (ADMs), digital cross connects (DCS), and DWDM transport into a single integrated platform for a wide range of economical and service related benefits, including reduced capital expenditures, lower operations costs and simplified network and service management.
