Infrastructure Agility Messenger cable Source: Corning Source: Corning

• Better macrobend performance enables small cable designs mitigating attenuation losses caused by the tight packing density

• A more macrobend resistant fiber enables smaller, lighter and more flexible cables • These cables allow the use of smaller diameter messenger wire for aerial solutions

• What operators are saying: We’re willing to explore all kinds of solutions that allow us to reuse existing space, everything is getting cramped Source: Corning

• Lighter and more flexible cables are more suitable for 4G (LTE) small cell deployments

Our main design issue today is that our splicing cabinets are completely full. We used bend-insensitive fiber to deport some of the cable outside and coil it tightly to create some extra-space in there Source: Diffraction Analysis & Corning market research, 2013

Improved macrobend performance enables smaller, lighter and more flexible cables that can advance network infrastructure agility Optical Fiber

Infrastructure Agility Better Space Utilization • Higher fiber count per duct:

Reduced Construction Costs • Avoid CapEx of additional trench construction and duct installation which typically cost more than US $10,000 per mile

Source: Corning

Reduced Duct Space Rental

• Reduced duct congestion:

Source: Diffraction Analysis and Corning estimates

A small diameter cable can speed up cable deployments by reducing the number of blockages

Net Present Value (NPV) 25,000 € 20,000 € 15,000 €

• Small hardware & equipment Smaller cables enable smaller hardware and equipment in access networks

Cable diameter reduction

• A 30% reduction in cable diameter can save up to €20,000 per cable kilometer in duct leasing fees*

Bend improved fibers enables smaller diameter cables that reduce duct rental and construction costs, ease congestion and enable higher fiber counts Optical Fiber

The same industry leading low-loss of SMF-28e+® LL fiber: • Capacity robustness: 100G, 400G, NGPON & WDM PON • Low cost capacity: equipment reduction, longer reach, optical switching • Enhanced subscriber coverage • Repair resilience • Infrastructure consolidation

The same improved bend performance of ClearCurve® XB fiber: 33% better bend than G.657.A1 standard  Capacity robustness: NGPON, WDM PON  Advanced cable design  Space optimization  Aerial deployments 

Four huge benefits.

• MFD transparency and 100% compatibility allows for seamless integration into existing G.652.D networks
