Fiber Market Summary
• Increasing network speeds requires more fiber
– Long haul – more capacity per cable
– Access – network convergence and 5G densification
– Data Centers – More east west traffic from new
applications (AI) drives more devices
• More challenging requirements at network edge
• Fiber + cable innovation to increase capacityOptical Fiber Technology and Trends

CommScope – Principal Field Application EngineerHyperscale 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)

Current Large Data Centers vs. Micro Data Centers near cell towers Latency differences between 4G & 5G infrastructure, with supportive use case — Source: Mutable.io5G is coming and how will it impact you….
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.

Where do you start ?
• Think fiber first
• 5G Small cells & Cameras
• IoT & Edge Data Processing
Top / Middle / Bottom SolutionsIn 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!
