ABSTRACT:
A transparent optical distribution system which is tolerant to system variations and extension in future, such as the choice of analogue or digital signals, bandwidth, bit rate, the number of services and connections per subscriber comprises a common terminal unit (3) provided at each subscriber's premises. The common terminal unit (3) comprises an input (100) connected via a power splitter (4) to a distribution box (40) which has a plurality of outputs (45-49) each connected to a respective wall socket (20-24). A second distribution box (50) has a plurality of inputs (55-59) to which the wall sockets (20-24) are connected and outputs (51-54) which are connected via a power splitter (5) to the input (100) of the terminal unit (3). A third distribution box (60) has a plurality of terminals (66-70) connected to the wall sockets (20-24) and a further plurality of terminals (61-65) connected to a power splitter 6 whose output is connected to a mirror (7). Intercommunication between terminals (I-IV) takes place via the third distribution box (60) and is independent of incoming and outgoing signals.
