Optical Fiber Transmission System

A method for identifying a remote component in an optical fiber transmission system,

• wherein an optical identification signal carrying an optical identification signature is transmitted to the remote component comprising an associated passive identification unit which provides an identification of a component type of the respective component on the basis of the optical identification signature.

A method for identifying remote components deployed in an optical fiber transmission system comprising the steps of:

• (a) transmitting by an identification transceiver optical component type identification signals each having an identification wavelength associated with a corresponding component type within an identification wavelength range outside a data wavelength range used for optical data signals transmitted at predetermined channel wavelengths by an identification transceiver to remote components;
• and
• (b) receiving by said identification transceiver optical signals which are evaluated to detect an optical component type identification signal having a valid component type identification wavelength looped back by a passive optical identification unit associated with a remote component to identify the component type of the respective associated remote component deployed in said optical fiber transmission system.

A component of an optical fiber transmission system, said component comprising a passive optical identification unit which is adapted to provide an identification of a component type of the component by a remote identification transceiver of a central office by means of an optical identification signal having an identification signature associated with the respective component type of the component and looped back by the passive optical identification unit to the remote identification transceiver of the central office.

A central office of an optical fiber transmission system comprising:

• at least one identification transceiver adapted to identify remote components in an optical fiber transmission system, including (i) an identification transmitter adapted to generate and transmit optical component type identification signals each having an identification signature associated with a corresponding component type of a component, and (ii) an identification receiver adapted to receive optical signals to evaluate received optical signals to detect an optical component type identification signal having a valid component type identification signature looped back by a passive optical identification unit associated with a component to identify the component type of the respective associated component deployed in said optical fiber transmission system;
• and
• data transceivers adapted to transmit and receive optical data signals at different channel wavelengths being connected to a multiplexing unit adapted to multiplex transmitted optical data signals onto an optical fiber being connected to an optical combining filter which is adapted to combine the multiplexed transmitted optical data signals with the optical component type identification signals provided by the identification transceiver of the central office.
