There are two main structures emerging as candidates for a future fibre-based local network. The star topology with its dedicated feed to each customer has been the mainstay of telecomms networks to the present day. It offers simplicity, flexibility for upgrade, and security (i.e. customer independence), and so remains a major contender as fibre is introduced. However it is the distributed-star network (DSN) structure of Figure 1 that is the most viable form of this topology for the foreseeable future. Here the star connection is from a remotely-sited equipment node near to the customer rather than all the way from the exchange. This reduces the fibre content of the network, and more importantly makes fibre handling more manageable.There are already fibre fed remote telecomms multiplexers and switched-star cable TV schemes being installed. They both match the topology and can come together to make a multi-service distributed-star network.
