Network comprising converters between electrical and optical signals

A network in for example apartment buildings having a partly optical transmission of information between subscribers (29) and a centrally arranged switch (3) have connector housings (9) comprising an electrical connector (9) at one end and a connection terminal (21) to an optical fiber at the opposite end. An electronic converter for converting between electric and optical signals is connected between the electrical connector and the optical connection. The electrical connection can be coupled to an electric connector (17) of the switch by a detachable electric connection cable (13). The converters in the connector housings are designed so that the optical transmission, in regard of the signals, as seen from the switch, operates as an electric signal line.
