8 100G Metro DCI- Reality Check In last 2 years,100g surged 10x but majority is long haul deployments (75% in 2014) In 2016, 50% of deployments will be 100G in metro regional and access markets Ports(%) 100% 80% 60% 40% 20% 0% Source: IHS Infonetics, April 2015 Year Long Haul (>600km) Metro (<600km) Is there a right 100G solution? Metro Access (<100km) 8

9 100G Ethernet Metro Gap Problem Cost per bit Flexibility Metro-Cloud Interconnect Requirements Reach Power Capacity 9

10 Passive 100G Transport ACTIVE Conversion from client ( grey transceivers ) to line ( colored transceivers ) signals by transponder cards Since being acave a chassis with power and management (SNMP) is needed PASSIVE No conversion, transport transceivers are plugged straight into terminal equipment Less acave elements => higher reliability, less latency Flexible but complex Transceivers are managed by terminal equipment (Switch, DSLAM, etc.) AC DC SNMP

11 Non-Standard Coherent vs. Direct Detect Complex phase & amp modulation, less sensitive to CD & PMD, so wider reach 100Gb/s PM-DQPSK per lambda Tunable Coherent Direct Detect 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 11

17 Conclusion 100Gbps is quickly becoming de facto transmission speed 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, with no clear winner. 17
