2 G.fast timeline G.fast proof of concept Early operator lab tests G.fast prototype More lab tests Early field tests First G.fast products Larger field trials Early G.fast deployment 2
3 G.fast field trials 21 G.FAST TESTED WITH 21 OPERATORS +7 MORE TRIALS PLANNED 652 Mbit/s US+DS traffic (74m in-house cable) Four Acres test facility 5
4 Crosstalk in G.fast has a much bigger impact than in VDSL2 Channel 0 db Direct signal Cross-whispering Cross-SHOUTING Crosstalk signal -70 db MHz VDSL2 106 MHz G.fast I 212 MHz G.fast II Frequency 6
5 Different precoding strategies exist to cope with this high crosstalk Transmitter Channel Receiver Power TX Precompensation Linear precoding Scaling causes SNR loss XTALK TX RX Nonlinear precoding Modulo reduces transmit power Higher bitloading 7
6 Modulo operation introduces a power penalty to guarantee PSD mask compliance Modulo bounds transmit signal to square constellation Uniform distribution within square is assumed to guarantee PSD mask compliance The G.fast standard defined new 3-bit constellation to lower excessive power penalty G.fast constellations are NLP-ready Power penalty 2.5 db VDSL2 G.fast Diamond 0 db 1 Constellation size [bits] 12 Neckebroek et al., IEEE ICC 2015, 8
7 The nonlinear modulo operation increases the gap to capacity for small constellations The modulo operation creates additional nearest neighbors for the outer constellation points 4-QAM example 1.5 db 1 db Coding gain degradation 0.5 db 0 1 Constellation size [bits] 12 Impact is largest for the smallest constellations, due to the larger fraction of outer constellation points Neckebroek et al., IEEE ICC
8 Nonlinear precoding gain is only significant at high frequencies 1 Gbps Nonlinear 106 MHz 212 MHz 2 Gbps +30 to 40 Mbps +100 to 250 Mbps 850 Mbps Linear 1.5 Gbps Nonlinear Linear 700 Mbps 1 Gbps Line index Line index +5% +15% Very short cable with very high crosstalk 10

11 Fiber To The NODE CURB MANHOLE POLE BUILDING DRIVEWAY FRONTDOOR VDSL2 VECT >200 METER >100 SUBSCRIBERS G.fast <200 METER 10s OF SUBCRIBERS XG-FAST 10s OF METERS 1 SUBSCRIBER 14
12 A homes passed fiber network A homes connected copper network Distribution Point Unit Single or very few subscribers Very close to end user High bandwidth backhaul NG-PON2 Aggregation Street Reverse powering User doesn t need to power shared hardware Short cables have low resistive loss Multiple pairs per subscriber No/little inter-user crosstalk High intra-user crosstalk 15
13 XG-FAST does not replace FTTH, but is to be considered an integral component of FTTH deployments Accelerates the roll-out of FTTH services XG-FAST Complementary to FTTH Avoids the logistic nightmare of installing fiber on each customer premise Gigabits for all Up to 10 Gbps on shortest loops 1Gbps symmetric for all 16
14 XG-FAST physical layer concepts Bonding 2 twisted pairs High crosstalk at high frequencies Vectoring Crosstalk contains detectable signal energy We use crosstalk to increase the capacity (constructive interference) Two sided coordination TCAM Transmitter Controlled Adaptive Modulation Automatic adaptation to varying channel conditions Allows operation at 0 db SNR Margin Increases spectral efficiency 18
15 Transmitter Controlled Adaptive Modulation (TCAM) enables fast and autonomous rate adaptation Q Each DTU is assigned to one hierarchic layer RX acknowledges successful DTU receptions TX notices when some layers are not received TX autonomously shuts these layers down and retransmits the DTU in a more robust layer I Fast and autonomous rate adaptation Lower SNR margins Higher throughput Layer 1:3 < Layer 1:2 < Layer 1 Increasing robustness Decreasing capacity Timmers et al., Bell Labs Tech. J. 18(1), pp ,
