<p>The invention relates to telecommunications network (10), and in particular to a Passive Optical Network (PON), and a method for operation thereof. The telecommunications network (10, 60) is capable of handling increases in bandwidth per user over the predicted lifetime of the network infrastructure. The telecommunications network (10, 60) further utilises a greater proportion of the potential bandwidth carrying capacity of the network and minimises maintenance requirements. The network (10, 60) is readily adaptable to future bandwidth requirements because redundant optic fibres (18, 27) are provided for making more connections as required. The cost of laying redundant optic fibres (18, 27) is minimal when compared to the cost of laying additional optic fibres at a later date. Furthermore the cost of maintaining the network is kept to a minimum because of the use of PON technology and consequently the overall cost of installing and maintaining he network over a predicted lifetime of 20 years is reduced.</p> |
