Data Center Summit

Data Center Summit: Data Center Optical Interconnect - Technologies and Markets

Tuesday, 13 March, 10:15-12:15
Theater II, Hall E
Session organized by OFC’18 N5 Program

Session Description

To many in the optical networking industry, data center means these massive buildings with servers, storage and switching that run cloud infrastructures for the likes of Amazon, Facebook, Google, Microsoft and others. In reality, the market connecting data centers poses a different opportunity for network operators. The needs for this market are quite diverse from the traditional optical networking ones and depend on what type of data center is involved. The various types of data center operators, their needs and how they are being addressed will be discussed in details.
Panelists will be invited from industry experts and debate the following with specific focus on technology, applications, deployment scenarios for data centers:
  • What are the different types of data centers and how do they connect to each other?
  • How is the cloud data center driving new generations of optical interconnects?
  • What are the current technologies and equipment being used to address this market
    • Layer 2 – Ethernet over DWDM
    • Open Optical Line Systems (OOLS)
    • Packet Optical
    • Carrier Ethernet
    • Pluggables – 100G for DCI
    • Coherent - CFP-DCO, CFP2-ACO and CFP2-DCO  
  • What are the new technologies being developed for higher data rates?
    • 400G and beyond – will the equipment be the same, just upgraded to 400G or do we need a new ecosystem?
    • CDFP, CFP8, OSFP, QSFP-DD – will all have markets and if so, where?
    • 400G ZR challenges and roadmap
  • What are the potential architecture and roadmap after 400G?
