G.Fast1Gbps over Copper Cable

“Are we ready ?”By

Rommy Kuntoro

What is G.Fast ?• Ultra high data rates

• Bandwidth: 2-106Mhz - Up to 1Gbps in Amd 1/ 2 on a single pair, double with bonding• Bandwidth: 2-212Mhz - Up to 2Gbps in Amd 3 on a single pair, double with bonding

• Using Time Division Duplexing ( TDD ) Technology (not FDD like VDSL)• Provide ratio control Downstream/Upstream bandwidth ( 90/10, 80/20 , 50/50, 70/30 )• Dynamic Time Slot Allocation (dynamic upstream/downstream) ratio for future

• Vectoring is part of the standard

• Robust operation – self install friendly• Fast OLR ( online reconfiguration)• Ability to quickly track changes on the line (precoder updates)• Short retrain time

• Low power consumption• Discontinuous operation• DRA ( Dynamic Resource Allocation )

G.Fast is ITU Standard (G.9700/G.9701) for local loops shorter than 500m
