100G and Beyond DC Interconnect: Present and Future
•

The insatiable desire for more capacity and faster datarate arising from the explosion in bandwidth-intense applications necessitates deployment of higher capacity WDM systems in both inside datacenter and metro datacenter interconnects systems. This demand for higher datarates is reflected by the numerous standardization and study groups commenced in the last couple of years. While the standardization scrutinizes the requirements for smooth migration for a datacenter interconnect with distances of upto 40km, the upgrade to high capacity DC metro access networks (beyond 40km), where no standardization exists, needs to address the economic viability together with greater space, power and bandwidth efficiency requirements. This presentation focuses on both of these areas and elucidates the current trends and evolving technologies to deal with the dynamically shifting landscape of DCI.
