1. Discover Optical Ethernet
Prepare your infrastructure
for the broadband access challenge
There can be no doubt – new bandwidth-consuming
services will drive the evolution of telecommunication net-
works in coming years. The broadcasting of multiple high-
definition TV channels, distribution of high-quality video,
and video communication represent just a few examples.

• Single protocol for complete

• Gigabit capacity to multiple

• Minimum number of central of-

• Simplified network operations

photonic network)
• SDH investment protection
