G.Fast moving forward
« on: December 13, 2013, 05:58:46 PM »

"The International Telecommunication Union (ITU) yesterday gave initial approval to a data transmission standard capable of 500Mbps speeds in both directions over existing telephone wires. The new standard, G.fast, can be used on phone lines within 250 meters of a distribution point, benefiting fiber-to-the-node deployments. With telcos not having to build fiber on the proverbial "last mile" (or, really, 250 meters), this could bring fiber-like speeds to many more homes."

Ubfortunatly data transmission standards don't seem to take account of real world interference !

I sometimes think they are drafted by people with an electricians view of electricity; it flows down a wire like water inside a pipe full stop.

Perhaps this is only expected to be used for FTTP distribution within a housing block ?

Otherwise has anybody considered the vast costs of re-doing a middle-mile fibre distribution** from the current fibre aggregation points through blocked and over-full ducts as well as the costs, residents' power consumption and support logistics, for a vastly increased micro-cabinet count.

All the FTTCs around Surrey only have either four or eight fibres terminated in a box without expansion capacity and usually with a very few empty tubes as well. That's why a full re-implementation from the fibre aggregation point is required.

Kind regards,
Walter
