Fiber to the Distribution Point
 Push fiber further to the edge of the subscriber drop
-
No gap in subscriber marketing for sub-gigabit service
offerings
"Fiber powered" service
 Close coverage gaps in FTTP build
-
MDUs
Business case-breaking drops (buried, impervious cover,
no ducts...)
 Unprecedented speeds over copper
-
Vectored VDSL2 provides 100Mbps+ in these
environments
G.fast increases to 500Mbps+
 Enables success-based transition to end-to-end FTTP
-
Control installation of difficult drops
 When you choose to offer
these subscribers a gigabit tier
 When individual subscribers order it
© 2015 ADTRAN, Inc. All rights reserved.
31
What is G.fast? Gigabit over Copper
 DSL acceleration technology
- DMT-based like VDSL2/ADSL2+
- Uses wider spectrum to achieve
higher rates (106 MHz or 212 MHz)
- Very high rate requires very short
copper loops – FTTdp or FTTB
 Gigabit service over Copper
Optical Fiber
Metallic Cable
< 1,000m
$
< 150m
- Provisionable (a)symmetric rates
 Operational considerations
- Customer self-install saves cost
- Cost per port sensitivity due to
distributed, low density solution
(<16 ports; FTTdp deployed)
- VDSL2 and G.fast co-existence
consideration
- Reverse power saves cost,
provides redundancy

Very high rates, very short loops
 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 must be vectored
- Highly crosstalk sensitive
Less than 100m and vectoring required for Gigabit
© 2015 ADTRAN, Inc. All rights reserved.
33
G.fast Overview
 Defined in ITU-T G.9700 and G.9701
- DMT-based like VDSL2/ADSL2+
 Wider spectrum = Higher rates
- 2.2 MHz up to 106 MHz or 212 MHz
 Very high Frequency = Higher Attenuation up to 250m
- Best for shorter copper loops (<200m)
- Vectoring comes ‘standard’
 Tunable Upstream (US) and Downstream (DS) rates
- New Service Opportunities
- Advertised Data Rates are combined US/DS

REVERSE POWER CHALLENGES
• Local – Practical for MDU applications when
building owner provides access
• Single subscriber must power DPU when only a
single user is connected
• Remote powering – Well known and available but
not always practical for FTTdp deployments
• Must guarantee fairness for multi-subscriber
• Reverse power feed – Well suited for short loops
• Described in G.fast standard (G.9701)
• Specified in BBF (WT-301)
© 2015 ADTRAN, Inc. All rights reserved.
• Conflicts with legacy POTS DC feed and signaling
• Workaround with POTS adaptors
• Manage the DPU even when powered down
• Subscriber self install

Summary
 The market is driving
operators towards all-fiber
networks that can deploy
any service
 This requires an access
platform that is scalable
and can evolve
 ADTRAN has a large
toolkit of solutions to costeffectively reach that goal
