BT to investigate remote-node setups for fibre-copper broadband

First BT Fibre-To-The-Remote-Node FTTrN Broadband Trial Set For Q4 2014 | ISPReview.co.uk

My Comments

British Telecom are trialling in Yorkshire a deployment setup for fibre-copper (FTTC, FTTN, etc) next-generation broadband setups. This is based around a miniature housing containing VDSL2 DSLAMs that can be mounted in smaller locations and able to serve a small number of copper connections.

This system, known as FTTrN (Fibre To The Remote Node) allows for longer fibre runs and can be powered either by the client premises or by a low-power independent power supply like a solar panel or simply neighbouring electrical infrastructure. It is intended to be mounted on telegraph poles, installed in small manholes or integrated in to existing infrastructure in some other way.

This is pitched as an alternative to the street cabinet that is essential to the FTTC (Fibre to the Curb / Fibre To The Cabinet) model because these have costs and installation issues as their baggage. This includes aesthetics and streetscape issues including attractiveness to grafitti vandals as a tagging surface as well as assuring dedicated power-supply availability.

Useful for difficult installations where a street cabinet would be difficult to install – cosmetic issues with large cabinets including attractiveness to grafitti vandals, planning / streetscape integration, dedicated AC power requirements including cabling infrastructure

Personally I would see these setups appeal to fibre-copper setups like “fibre-to-the-node” / “fibre-to-the-distribution-point” where the bridge between fibre-optic infrastructure and copper infrastructure is closer to the customer. They also do appeal as a way to “wire up” remote settlements, estates and hamlets with next-generation broadband in the fibre-copper way while assuring improved throughput.

I do still see these having the same limitations as any fibre-copper setup where the user experience can be impaired by use of poorly-maintained copper infrastructure which would be a common problem with rural installations.

At least BT are trying out a highly-flexible fibre-copper next-generation broadband setup which can also appeal as a tool for supplying real broadband to rural areas especially where there are the remote settlements or estates.
