Huawei has introduced a new access network architecture that it says will overcome the installation difficulties in traditional fibre-to-the-home (FTTH) or fibre-to-the-building (FTTB) scenarios. The Chinese vendor has introduced what it calls fibre-to-the-door (FTTD), which provides broadband at speeds up to 1 Gbps by reusing existing twisted-pair or coaxial cables in the final drop.
The FTTD equipment is deployed just beyond the boundary of the end-users premises, either at an outdoor position in the street, or in the corridor or telecom riser inside multiple-occupancy buildings. This avoids the need to gain permission to enter individual homes to install equipment, which speeds up and simplifies the installation process significantly, the company claims.
Broadband over existing twisted-pair cables is provided by VDSL2 and in the future Giga DSL – a new technology being developed by Huawei that provides combined upstream and downstream data rates of 1 Gbps within 100m to groups of up to 50 end points.
The FTTD equipment draws power from the customer modem, avoiding the delay and expense that would be incurred installing power supplies to thousands of nodes in the street. Service provisioning, operations and maintenance functions are provided by the existing FTTH OSS software.
Reverse power is a crucial part of G.Fast, the forthcoming specification that will deliver 250 Mbps download speeds over twisted-pair cables at distances up to 200m. However, G.Fast is unlikely to be complete until 2014, while Huawei says its proprietary FTTD equipment has already been tested on live networks, and is about to be put into trial commercial use in Europe and the Middle East.
FTTD is part of Huawei’s SingleFAN broadband access product portfolio.
