Session Abstract

While the deployment of the new 100Gig Internet2 Network provides an opportunity for the
Internet2 community to redefine advanced networking for research and education, it also presents
many universities and connectors with a challenge -- how to cost effectively deploy 100 Gbps
transport infrastructure from their respective campuses to access the nearest Internet2 hub. This
panel discussion will review practical, cost-effective solutions for enabling 100 Gbps wavelength
connections from research & education networks to the Internet2 backbone. The advanced
modulation for 100 Gbps optical transport enables 100G wavelengths to be easily added to
existing 10 Gbps DWDM systems. See which vendor solutions support this functionality. The
monthly recurring cost operating expenses of colocation (i.e. space, power, cooling, etc.) can,
over time, outweigh the capital costs of equipment. Learn how the various vendor solutions
address these factors. Come see which vendor solutions are compatible with 100GHz and 50GHz
DWDM modulation schemes and can operate on any available wavelength within current 40- and
80-channel DWDM wavelength plans. Discussion topics to include: • What are the current network
topologies and equipment options for implementing 100Gbps access connections? • Learn how
incremental cost per Mbps of bandwidth is impacted with 100Gbps versus the cost for existing
10G systems. • What is the typical reach using the new 100Gbps coherent detection solutions? •
Which vendor solutions can be configured as a muxponder or transponder thereby aggregating
and/or transporting any mix of 10 Gbps, 40 Gbps and 100 Gbps services over a 100 Gbps OTN
connection?
