G.fast: Gigabit Broadband, at Much Lower Cost!

Challenges for FTTH Deployment

Final access to the premise is the most expensive

(up to 50% of FTTH cost in last 100m)

Customers refuse intrusion (yard, wall, building)

Historic buildings pose a challenge

Practical Considerations for G.fast Deployment

Fiber penetration deeper into the network is

a major pre-requisite for G.fast deployment

Reverse power feed is a requirement for the

majority of deployments

VDSL fallback and

coexistence is necessary for

large scale deployment CPE self-install and zero-touch DPU provisioning

are key carrier concerns

VDSL Fallback: When is it Required?

VDSL2 MDU/DPU gets replaced with G.fast capable MDU/DPU

Serve customers who are beyond G.fast reach

Phasing out copper network

Offloading VDSL2 from cabinet to DPU

Customer moves to a G.fast location with his legacy CPE

VDSL2 (still) offered from cabinet
