GE - GBIC Ethernet Keeps Growing

• In the early days of Ethernet, our industry never thought that the Technology would scale

• With the advent of Ethernet Switching in the late 80’s and increasing speeds, that view has changed

• In the 90’s, this popular “LAN” technology began to make serious inroads into the WAN

• The WAN has traditionally been the dominated SONET, WDM and IP

• Ethernet in the WAN is carried over these existing technologies: SONET (POS), WDM, IP/MPLS, or Ethernet Switching/VLANs

The first to offer a true 10Gbps Ethernet over WDM across the Atlantic Ocean (LAN PHY 10.3125 Gbps) spanning over a submarine segment more than 6,000+ kilometers Hibernia Ethernet Offering

• Ethernet over SONET (POS) and WDM is dedicated = shared environment

• NOT a contended service like IP/MPLS and Switched Ethernet

• Hibernia Service Offerings – On FE Interface: 10Mbps, 50Mbps, 100Mbps – On GE Interface: 50Mbps up to 1000Mbps in increments of 50Mbps – On 10GE Interface: LAN PHY 10Gbps (10.3125Gbps) – On OC192 Interface: WAN PHY 10Gbps (actually 9.29Gbps)

• Hibernia Ethernet Advantages – Dedicated bandwidth – Ethernet over SONET is always transparent – Higher Security, dedicated POS channels for each customer – Fixed Routes = Fixed Latency – Protection offered like standard SONET /SDH product sets Thank You
