Abstract
An optical device () for an optical network, comprising an optical input (), a passive optical component (), a memory device () for storing information relating to the passive optical component. The optical device further comprises an optical splitter () configured to power split off a portion of received optical signals to form split optical signals and to output the remaining optical power of received optical signals to the passive optical component and a photodetector () configured to receive the split optical signals and to generate a corresponding photodetector output signal. Further the optical device comprises an accumulator () configured to be charged by the photodetector output signal, a laser () configured to be powered by the accumulator and a controller () configured to, in response to a trigger from the photodetector, read said information from the memory device and to cause the laser to transmit an optical signal from an optical output (), the optical signal carrying a message based on said information read from the memory device.
