This video shows the inside workings of the Openreach (BT) fibre-to-the-premises network from exchange to premises. It offers a useful enginner's eye view of the network, cutting out the streetside cosmetics.
The video shows you everything from the exchange (headend / ODF) to aggregation nodes, splitters, Connectorised Block Terminals (CBT) and then all the way to in-home Optical Network Terminal (ONT / ONU). Overall, it’s significantly more informative than most of the videos out there and well worth a watch if you want to understand how FTTP works on Openreach’s platform.
