‣ 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
