Agenda

Be efficient in deploying your passive network infrastructure

Factors of influence driving your efficiency in deploying your passive network in the distribution network and MDU

Focusing on:– Cable placement methods from the FCP (Fibre Concentration

Point) to the building– Termination methods and the right fibre type for the MDU

Deployment FactorsConsider Variables That Impact Deployment Speed and Cost

• Regulation

• Local rules– e.g., aerial or buried deployment

• Structure of deployment area

– e.g., mix of Single-Family Unit and Multi-Dwelling Unit

• Building architecture

• Expected penetration levels

• Network design and deployment technique: simple and flexible– Typically more than 50 percent of costs are installation and labor

• Availability of skilled workforce

• Quality/reliability

FCP to the Building: Various Deployment TechniquesNo “One Fits All Solution”Duct/cable placement methods have a substantial impact to total deployments costs in the distribution network

– Choosing an optimal cable routing is crucial to save cost – Important for deployment speed: saves time and increases deployment speed

It is key to mix and match different deployment types to optimize deployment costs and to meet deployment restrictions (geographical conditions, local regulation)

• The common methods and their options:– Aerial installation

• Pole mounted• Façade

– Buried installation• Digging (direct-buried cable or ducts)• Core removal • Installation in gas or water pipes• Installation in rivers and waterways• Installation in sewer pipes• Horizontal drilling technology• Micro-trenching in sidewalks and roads• Blown fiber

Assumes single deployment method for entire cable route (excluding drop)

The costs for each methodology will vary widely for many reasons. Therefore, each method will have a “range.”

Deployment Efficiency in the MDUMDU Factors of Efficiency

No “one fits all solution”: we learned that each building is different

– MDU network architecture is driven by • Building size (size S to XL, from direct drop to central riser, etc.)• Projected take rate (drives solution choice and termination technique)• Local requirements (indoor/façade)

– Deployment speed• Solution choice (splice, precon, etc.)• Required skill level for installation

– Regulation • Fibre count, # of basement terminals, termination technique

– Network quality & power budget• Factory-built & tested components vs. field installation• Bend-insensitive fibre
