Climbing down a sewer manhole
Geo is a super-fast broadband company that sells dark-fibre connectivity, mostly to businesses.
On Tuesday, Geo took ZDNet UK underground near the London 2012 Olympics site to see the sewer-based cabling that carries the company's fibres under the capital. Geo has 107km of cabling in London and around 3,000km overall across parts of the UK.
Geo does its initial connection planning using Google Earth, which helps it figure out where the customer's building is, how far the network is from those premises, and where the best manhole access to the sewers is to be found.
