Carriers Rising to the Challenge
Nice thing about Standards….
…So many to choose from!
The Google Factor!

Telco’s Path to Gigabit: FTTH vs. FTTdp
FTTN VDSL2/ ADSL2+
FTTx Vectored VDSL2
FTTH
FTTdp G.fast
Cost
10Mbps 100Mbps 1Gbps
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
