Optical Access Platform

The Larscom 4800 is an optical add/drop multiplexer that offers versatility in extending carrier-class backbones to the network's edge in a small footprint and at a reasonable cost. Aimed at network service providers and enterprises wanting to aggregate multiple services, such as voice, data and video, the device provides high-capacity optical broadband access onto a SONET or SDH transport backbone. Its software-defined processing backplane allows the device to terminate multiple optical streams, giving it the scalability and flexibility service providers and enterprises need to quickly meet rapidly growing bandwidth demand and increasingly complex access requirements.

It supports both SONET and SDH in a single platform, allowing this optical broadband access platform to satisfy the needs of service providers in both the domestic and international markets. Able to terminate multiple optical streams in a single unit, the platform also addresses the enterprise's requirement for multiple carrier access to a corporate facility.

Its self-configurable soft backplane makes it possible for the product to automatically update its configuration as interface modules are added. Because the matrix is software-driven, the six interface slots can accept any of a variety of interface modules, which will support T1/E1, T3/E3, OC-3/STM-1 and OC-12/STM-4 traffic with planned support for OC-48/STM-16. It delivers all services transparently, including IP-oriented services and legacy TDM (Time Division Multiplexing) services.

The device is easy to manage, with support for local access via an RS-232 connection and remote access via 10 Mbps Ethernet using telnet and/or SNMP. Additionally, the platform's low power consumption (less than 50 watts) and small footprint (3RU for a 19-inch rack) helps service providers and enterprises to meet their site installation budget requirements. The product provides a streamlined package optimized for flexible provisioning of optical bandwidth.
