New requirements on access architecture

> Support of existing and new applications and services• Triple play (voice, data, video)• Multi-party sessions (gaming, video conferences)• Peer-to-peer delivery models• Nomadic use

> Supporting different business models


Overview


> Trends in Access





Fibre access in MUSE

> Integration optical first mile in end-to-end architecture• PtP Ethernet• Ethernet GPON / EPON

> Research on specific technologies


HFR over multi mode fibre

> Potential low cost, short range access with transparent connection to a wireless home network


Hybrid Fibre VDSL

> Lower power consumption at the cabinet

> Smaller cabinet size

=> lower operational cost
