‣ 100Mbps is the short-term goal for most service providers

‣ But 500Mbps–1Gbps is where providers need to be to compete long-term

Market Drivers for Ultra Broadband ‣ Gigabit service demand

• 500 Mbps and greater

• OTT service uncertainty

‣ Gigabit competition • MSOs, MNOs are Gigabit-ready

• DOCSIS 3.1, LTE-A rollouts

‣ Fiber deployment costs • The final 200m most costly

• Home visits, CPE and fiber installs

‣ Regulatory goals • FCC 100M squared

• EU Digital Agenda 2020

#gfast #fttdp

FTTN – Increasing 100 Mbps Coverage

11

What Is Vectoring?

12

‣ Challenge: • Crosstalk is the dominant factor which limits the rate-reach

performance of VDSL2

‣ Solution: • Vectoring: coordinate transmission and reception of DSL signals on

multiple copper pairs to mitigate crosstalk

• Principle similar to active noise cancellation headsets: adding compensation signals to DSL signals to cancel crosstalk

…what are the real-world benefits of vectoring?

… how much does it improve broadband rates?

… how mature does vectoring run in the field?

… how should I configure vectoring?

… how much does it impact CAPEX & OPEX?

The solution

Are You Ready to Boost Your Copper? Carriers worldwide are looking for solutions

to monetize their copper and fiber infrastructure!

FTTD: 250Mb/s Access w/ New Band Plan

‣ Fiber to the Door (FTTD): no in-home fiber re-wiring, no home visit, fast roll-out

‣ VDSL2: mature, low cost, easy deployment

‣ New feature: reverse power feeding

‣ Achieve 250 Mb/s downstream and 50 Mb/s upstream with frequency profile change (FT and Metanoia were pushing the standard)

FTTdp/FTTD VDSL2: Soft Speedup

‣ Soft Speedup: change US2 band to downstream with software profile change

‣ Improve downstream speed by 10%–20% with reduced upstream speed on longer loops

‣ Latest CPEs capable of supporting the profile with software upgrade

What Is G.fast? Answer: Gigabit over Copper

FTTdp is part of an operators Gigabit services tool kit

‣ DSL acceleration technology • Kind of, sort of like VDSL2/ADSL2+

‣ Gigabit service over copper • Provisionable (a)symmetric rates

‣ Operational considerations • Fiber-like benefits

• A lot of moving parts, options

• Cost-per-port sensitivity due to low density

‣ The G.fast standard outlines these rate/reach targets: • Gigabit @ <<100m • 500Mbps @ 100m • 200Mbps @ 200m • 150Mbps @ 250m

‣ VDSL2 (17a) with vectoring: • 100Mbps @ 550m • 150Mbps @ <200m

‣ G.fast will be vectored • Highly cross-talk (FEXT) or noise sensitive

Real-World Rates Should Beat Targets

A Clear Evolution to Gigabit Speeds

36

‣ Vectoring, FTTdp, and G.Fast offer a transitional approach to gigabit services

• Spread out capex while still satisfying subscriber bandwidth requirements

• Stay ahead of cable DOCSIS 3.0 and 3.1 rollout timelines

‣ Reduce opex by eliminating truck rolls and offering self-installation

‣ Build toward long-term upgrade to FTTH, while still using existing copper wiring
