Abstract

In an optical fiber network for connecting individual subscribers (105) a local switch unit (101) is provided. The unit is connected between the subscribers and a central conventional unit (109) such as a router. The switch unit can be connected to the central unit through a ring network (107) providing a redundant communication path from the switch unit to the central unit. In the switch unit preferably a local switching circuit board is arranged comprising a packet switch (213) for locally switching traffic between different subscribers and between the subscribers and the central unit. Various filters can be arranged in the switch unit for avoiding that a subscriber can gain access to information intended for another subscriber.
