OVERVIEW

Today, optical Ethernet advances promise to take Ethernet transport to levels undreamed of back then and not even feasible using copper technologies today.

This report explores the history and potential of optical Ethernet technology, focusing specifically on its impact on service-provider networks and services.

Optical repeaters were part of the first Ethernet standard back in the early 1980s.

TECHNOLOGY

In 1983, the IEEE 802 Local-Area Network/Metropolitan-Area Network Standards Committee (LMSC) released the 802.3 standard for Ethernet—a shared medium for LANs using a distributed media access control (MAC) mechanism called carrier sense multiple access with collision detection (CSMA/CD).

Ethernet was defined as an open standard in the early 1980s by a consortium comprised of Digital Equipment Corp., Intel, and XEROX;

ADVANTAGES OF OPTICAL ETHERNETADVANTAGES OF OPTICAL ETHERNET

Optical Ethernet offer high-bandwidth, low-cost, easy-to-learn and manage alternatives to traditional time-division multiplexing (TDM) metro technologies such as SONET (Synchronous Optical NETwork).

Optical Ethernet greatly reduces the amount of both equipment and power needed at scarce central-office rental property.

optical Ethernet access and connectivity that provides a secure, yet manageable, optical Ethernet demarcation point between the service provider and business user.

APPLICATIONAPPLICATION

1.OPTICAL ETHERNET FOR SERVICE PROVIDER

As a result of ethernet’s expansion into MAN and across the WAN service providers are looking for ways to provide connectivity services across the metro bottleneck between their enterprise customers and the service provider’s backbone. Nortel networks optical ethernet solution creates a metro network solution that supports any-to-any services over a scalable, easy-to-provision, carrier-grade network

2.OPTICAL ETHERNET FOR 2.OPTICAL ETHERNET FOR ENTERPRISESENTERPRISES

With Nortel networks Optical Ethernet an enterprise canBreak the bandwidth bottleneck by exploiting the simplicity of ethernet across the MAN and WAN.Optical ethernet allows businesses to seamlessly expand their ethernet LANs across the metro backbone and obtain cost effective network connectivity to enable a set of value added services and application.
