Abstract:
A device for detecting misconnections and/or measuring a misconnection time in a fiber optic telecommunication network, the network comprising network elements and fiber optics spans connecting the network elements, each network element comprising inlets for introducing bit streams in the network and outlets for extracting the bit streams from the network, wherein the device comprises:pattern generator/checker transmitter blocks generating sequences of test words, said pattern generator/checker transmitter blocks being connectable with said network element inlets for inserting test words, in said inlets, which are characteristic of the inlet at which they are introduced; and pattern generator/checker receiver blocks reading and decoding the incoming sequences of test words, said pattern generator/checker receiver blocks being connectable with said network element outlets for identifying said incoming sequences of test words and the inlet where the test words come from.
