57 Zusammenfassung AB [EN] A method for supervising an optical network termination unit (18) from a remote headend (14) that is connected to the termination unit through a fiber-optical link (20), the termination unit having an optical input side (32) receiving a transmitted signal (Tx) from the headend, and an optical output side (34) transmitting a signal to be received by the headend as a received signal (Rx), the method comprising the steps of: optically coupling said input side to said output side, thereby to form a passive optical loop, passing a loop control signal (LCS) from the headend through said loop, and detecting the loop control signal at the headend.
