Hyperscale DC Architectures Historically, DC’s have been a 3-tier topology – aggregation and blocking architecture Cloud data center networks are 2-tier topology
Optimized for East-West traffic Workloads spread across 10s, 100s, sometimes 1000s of VMs and hosts Higher degree (10-20X) of east-west traffic across network (server to server)

Data Centers– the brain of a smart communityBig data applications are driving:
• Speed & Size
• Microservices
• Location (moving to Edge)
Latency differences between 4G & 5G infrastructure, with supportive use case — Source: Mutable.io
Enterprise Hyperscale MTDC Edge DC
Current Large Data Centers vs. Micro Data Centers near cell towers
Wireless deployments will see a dramatic change in the landscape due to network densification.
Small cell tower deployments will surpass macro towers in dense areas, C-RAN topology optimizes new mobile deployments and edge data centers are moving closer to the user.
TREND:Ratio of small cells to macro cells:
2017 5 : 12023 30 : 1
5G is coming and how will it impact you….
Smart Poles – Concealment solutions
Where do you start ?
• Think fiber first
• 5G Small cells & Cameras
• IoT & Edge Data Processing
Think Smart Node!
Top / Middle / Bottom Solutions
In Conclusion• Increasing network speeds will continue to promote more fiber
usage• The different verticals from DC’s, Campus, Access, Edge, Metro,
Long haul etc. all show increases in fiber deployment/demand• Investments in fiber technologies are on the rise leading to
increased options• The need for multi-gigabit and terabit speeds, lower latency and
extended reach will continue to move fiber further into the networks
• So, Fiber is not just future it is Now!
