What is next in fiber?
� Gradual introduction when it is needed
to meet certain market needs
� GPON still has plenty of bandwidth
� First applications:
• Backhaul of huge MDUs
• Top-end customers
• Business users
NG never happens at once

Market research confirms that most GPON operators
consider 10G GPON as the next step
� 4 times more bandwidth (10G DS/2.5G US)
� Graceful migration: coexistence with
current GPON
� No impact on OSP, including fiber and
splitters
� Most economically viable path

Squeezing the copper further: VDSL2 Vectoring
Downstream bit rate [Mb/s]
80 VDSL2 lines in 300-pair binderresults from a research collaboration of Alcatel-Lucent with Swisscom Labs

Crosstalk = dominant disturber for VDSL2

Loop length [m]
Downstream bit rate [Mb/s]
Vectoring cancels noise (lab proven) - potential for very significant bit rate increase
Field trials starting in 2010
Crosstalk = dominant disturber for VDSL2
VDSL Vectoring = Noise Cancellation
� measure crosstalk from each line into all other
lines in binder
� cancel the noise with an anti-phase signal

300Mbps over 2 pairs @ 400m – Bell Labs “Phantom mode” innovative demo

300Mbps in 5 steps
Start with a 1st twisted
pair – good for about
100Mbps.
Add a 2nd twisted pair –
good for another
80Mbps.
Bit rate on pair 1 drops
due to Xtalk from pair 2.
Create a 3rd virtual pair or
‘phantom mode’ pair – another
50Mbps.
BUT: bit rates on pairs 1 & 2
drop due to Xtalk from
phantom pair.
Apply vectoring
(crosstalk cancelation)
to boost bit rate by
approx 50%.
Bond the 3 links (2 physical
pairs + phantom mode)
creating one big 300Mbps pipe.
