Key Metrics in Network Deployment

Pace of Deployment– Minimize time to deploy network and

activate customer services

Cost - Minimize total deployed costs, including

all equipment, construction costs, power drops and permits

- Optimize deployed cost per bit

Network Performance– Maximizing bandwidth per user to meet or

exceed stated benchmarks– Increase number of users that can take

advantage of premium 100+ Mbps services

FTTN & FTTdp/B Challenges

Multi-technology access networks go a long way towards addressing key metrics, but challenges remain

Space Constraints Do we put the cabinet in the parking spot?

Aesthetic ImpactSo you want to put a

noisy cabinet in front of my gated home?

PoweringCoordinating with

utilities for local power drops

Alternative FTTN Deployment Option

Existing pillar with adjacent pit for cable access

Sealed DSLAMs located in pit and remotely powered

No aesthetic impact, no waiting on right-of-way permits and no waiting on local power drops Lowers cost and accelerates

deployment timeline

Same system level vectoring capabilities of traditional cabinet solutions but in a sealed form-factor

Multiple deployment options: pole, pit or vented pedestal

No right of way restrictions

Remote powering eliminates local power drops

Ability to deploy closer to the home through smaller node sizes increases bandwidth per subscriber

Sealed DSLAM Benefits

Lower total deployed cost per bit while accelerating deployment timelines for FTTN and FTTdp/B architectures

G.Fast offers 500+ Mbps performance in short loop scenarios (>150 m)

>5x the performance of VDSL2 for less than 10% of the total deployed cost

Field trials in 2014 and expanded GA deployments in 2015

Improving FTTdp/FTTB Performance

Small footprint ONUs for pit mount and basement

applications

Multi-technology access network is a key step towards improving pace of deployment and lowering the total cost of deployment, but challenges remain

Mix of deployment methods are required to optimize FTTN and FTTdp/B architectures

Operators around the world looking to sealed DSLAM solutions, remote powering and G.Fast to optimize FTTN and FTTdp/B deployment models
