Abstract

An optical distribution device has first connector points for the connection of incoming light waveguide cables, second connector points for the connection of outgoing light waveguide cables and at least one light waveguide connector cable having at least one connecting device on one or both ends for connecting at least one of the first connector points to at least one of the second connector points. Each connection device is provided with an electrical code memory device for storing an identification code and each of the first and second connector points are provided with an electrical code reader device connected to the associated code memory device for reading the identification code when the associated connector device is connected to one of the connector points. A controller is connected to the code reader device for evaluating the identification code to identify the optical connection effected by the light waveguide connector cable.

Claims

second connecting points for connecting outgoing light waveguide cables; and

at least one light waveguide connector cable via which at least one of the first connecting points is connected to at least one of the second connecting points, each light waveguide connector cable having opposed ends and at least one connecting device on at least one of the ends for connecting to the first connecting points or to the second connecting points, each connecting device being provided with an electrical code memory device in which an identification code is stored and the first connecting points or the second connecting points being provided with an electrical code reading device that is connected to the associated code memory device for reading the identification code, the code memory device being formed by an electronic memory chip that is electrically connected to the associated code reading device when the connecting device is connected to the first connecting points or to the second connecting points; and

a control device connected to the code reading device for evaluating the identification code to identify an optical connection effected by the light waveguide connector cable.

12. The optical distribution device of claim 11, wherein the code reading device comprises a printed circuit board on which there are provided one or more reading contact points that make contact with one or more mating contact components of the code memory device when the connecting device is connected to the first connecting points or to the second connecting points.

13. The optical distribution device of claim 11, wherein the identification code is formed by a multidigit code number, the last numeral of the code number defining the type of the light waveguide connector cable and the preceding numerals defining the light waveguide connector cable and the connecting devices.

14. The optical distribution device of claim 13, wherein the light waveguide connector cable is provided with a multifiber connecting device at one end and with a plurality of single fiber connecting devices at the other end and wherein the multidigit code number of each associated identification code is provided in the form of a serial enumeration, with the exception of the last numeral defining the type of the light waveguide connector cable.

15. The optical distribution device of claim 13, wherein the light waveguide connector cable is provided with a connecting device at both ends and wherein the associated identification codes are identical to one another.

16. The optical distribution device of claim 13, wherein the numerals preceding the last numeral of the code number are determined from the formula:
