Non-Standard Metro DCI Optics
• Complex phase & amp
modulation, less sensitive to
CD & PMD, so wider reach
• 100Gb/s PM-DQPSK per
lambda
• Tunable
• Based on simpler PDs, reach
limited by CD & PMD
• 25Gb/s ODB per lambda
• 4 lambda per 100G used
• 50Ghz or 100Ghz ITU-T grid
• Tunable

100G Direct Detect QSFP28 “ColorZ”
• Microsoft teaming with Inphi for worlds first 100G QSFP28 for metro DCI.
• Based on simpler PDs, reach limited by CD & PMD
• 50Gb/s PAM per lambda
• 2 lambda per 100G used
• DWDM 100Ghz ITU-T grid
• Connect data centers nearly 80km apart
• No need of active transponding in between
• Requires FEC on host board
• Tentative availability: 2017

Future Outlook Metro DCI
• Metro access market is only going to
grow
• Not just about datacenter interconnect-
enterprise, IXs, financial institutes
• Direct Detect deployments supersede
coherent after 2018
• Coherent opted when spectral
efficiency required, otherwise DWDM
Direct Detect proves to be the optimal
solution

100G and Beyond DC Interconnect: Present and Future
Excellence in Connectivity Solutions
• 100Gbps is quickly becoming de facto transmission speed
inside and outside Data Centers
• 100G switches moving towards higher port density with CFP2,
CFP4 and QSFP28 optics
• 200G and 400G Ethernet speed in development to meet the
continuous traffic demand
• It‘s a fragmented market

Passive 100G Transport

DCAC
• No conversion, transport transceivers are
plugged straight into terminal equipment
• Less active elements => higher reliability,
less latency
• Transceivers are managed by terminal equipment (Switch, DSLAM, etc.)
PA
SS
IVE
1310
• Conversion from client (“grey transceivers”)
to line (“colored transceivers”) signals by
transponder cards
• Since being “active” a chassis with power
and management (SNMP) is needed
• Flexible but complex
