Method and device for monitoring a detachable fiber-optic connection, especially in a fiber-optic transmission device or system

摘要

The invention relates to a method for monitoring a detachable fiber-optic connection, especially in a fiber-optic transmission device or system, comprising the steps of transmitting a wanted optical transmission signal carrying information data to be transmitted to at least one fiber-optic connection, a predetermined portion of the power of said optical transmission signal being reflected at the at least one fiber-optic connection depending on the status and properties of the at least one fiber-optic connection, creating a detection signal by detecting said reflected predetermined portion of the power of said optical transmission signal, monitoring and evaluating the detection signal as a function of time and creating a “DETECT” signal if the detection signal or a signal derived from the detection signal reveals a characteristic change in its course in time. Further, the invention relates to a corresponding device adapted to realize this method.

1. A method for monitoring a detachable fiber-optic connection, the method comprising the steps of:
(a) directing an optical transmission signal through one or more optical waveguides, each respective optical waveguide including a respective fiber-optic connection, and the optical transmission signal carrying information data to be received at a respective receiving device connectable to the respective optical waveguide through the respective fiber-optic connection, each respective fiber-optic connection reflecting a portion of the power of the optical transmission signal, the reflected portion of the power of the optical transmission signal depending on the status and properties of that respective fiber-optic connection, (b) creating a detection signal by detecting the reflected portion of the power of the optical transmission signal, (c) monitoring and evaluating the detection signal as a function of time, and (d) creating a “DETECT” signal if, irrespective of the power of the optical transmission signal, the detection signal or a signal derived from the detection signal reveals a characteristic change in course over time, the characteristic change in course over time being indicative of connecting or disconnecting a respective one or more of the fiber-optic connections.
