2007: FP6 project MUSE, Task Force 2:
• BT, TNO, Ericsson, ULUND, …
• Discussion: What comes after VDSL?• VDSL: 35 Mb/s up to 800m (with vectoring!)• VDSL: 80 Mb/s up to 400m (with vectoring!)• VDSL: 125Mb/s at zero meter• VDSL with vectoring & Bonding: increase to190%
• Discussion: will it be (full) Fiber to the Home?

1. And suddenly there was G.fast ….. ?
2008: FP7 project proposal “Omega DSL”:
• BT, TNO, Ericsson, ULUND, …
• Discussion: up to 1 Gb/s via 20-200m telephony cabling?• What are the techno-economic drivers for it?• Is it technically feasible via copper?• Can we transmit >100MHz via telephony wiring?• Can we initiate a world-wide standard for it?• Can we bring the industry into motion?• Aren’t we not too late for that?
• The next generation BroadBand requires up to 1 Gb/s !!

Multiple flavors of FTTH neededà into the Home à “Full” FTTHà upto the Home à “Hybrid” FTTH
G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])13
2. Techno-economic drivers for Hybrid FTTH
Hybrid FTTH is complementary to Full FTTHà into the Home à “Full” FTTHà upto the Home à “Hybrid” FTTH
Why: hybrid has possible techno-economic advantages• may save costs for digging/installation when copper can be reused• may save installation time, so faster roll-out
G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])14
2. Techno-economic drivers for Hybrid FTTHDigging and drilling:
- Too expensive- Not allowed in historical areas- Inconvenient in shopping area

G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])16
Hybrid FTTH (with G.Fast) brings opportunities• Less digging and drilling• Shortens installation time• Does not disturb customers• Allows for self-install in premises
(No appointment needed)• Postpones huge investment
2. Techno-economic drivers for Hybrid FTTHDigging and drilling:
- Too expensive- Not allowed in historical areas- Inconvenient in shopping area
Cost effective compared to Full FTTH!
G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])17
2. Techno-economic drivers for Hybrid FTTH
Hybrid FTTH reduces the amount of digging / drilling
• Digging in historic city centers is a problem• Digging in busy shopping streets is a problem
Quick-win
Example use case #1 – Dense areas

G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])19
2. Techno-economic drivers for Hybrid FTTH
In the past considered as the ideal Full FTTH scenario
• Full FTTH in practice far more complicated then aimed• Drilling in floors of all stacked meter closets, all in one day!• “Not in my Home” and “Not at Home” problems
G.fastnode
Quick-win
Example use case #2 – High rise buildings
G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])20
2. Techno-economic drivers for Hybrid FTTH
“Flashnet” was aimed at the ideal Full FTTH scenario
• Aimed for replacing copper by fiber in the future• But in practice it does not work that easy
Quick-win
Example use case #3 – “Flashnet”
Copper cable Tubes, with copper cables
Empty tube, aimed for fiber in the future MOKAP
Roughly 300 000 connections scattered all over the Netherlands
G.fast Summit, Paris, May 20, 2014Origins of G.fast - Rob F.M. van den Brink - TNO - ([email protected])21
2. Techno-economic drivers for Hybrid FTTH
Expected deployment strategy:• A mix between Hybrid and Full FTTH• Use Hybrid FTTH where attractive• Otherwise stay with VDSL, migrate to Full FTTH or
skip
Example use case ##– many others (country specific)
• From street poles (BT)
• Single Fiber extension (Orange)
• Mobile back hauling (Ericsson)
• etc
Various operators communicated
their use-cases in BBF
