A locking device comprising a lock body having a through hole, a bolt member having a longitudinal bore therethrough and an insertion end which is inserted into the through hole of the lock body. The bolt member is further having a retaining pin disposed within the longitudinal bore and a resilient means for biasing the retaining pin axially out of the longitudinal bore. When the bolt member is inserted into the lock body, a means within the lock body prevents the removal of the inserted bolt member therefrom, and engages an actuating means to actuate an identifying means. The identifying means transmits a signal to indicate whether the locking device has been tampered with or defeated. If the bolt member is cut, the retaining pin is displaced out of the longitudinal bore and dislodges the actuating means resulting in the identifying means indicating that the locking device has been tampered with or defeated.

An optical communication system ( ), a method ( ) for parallel modulation of an optical spectrum and a method ( ) for parallel demodulation of the optical spectrum of modulated optical frequencies by the system ( ) are described. The optical frequencies are provided in parallel to a modulation section ( ) for modulating with data bits from a data signal source ( ). The data bits are associated with an optical modulator ( ) that controls passage of the optical spectrum at a plurality of predetermined optical frequencies based upon the data bits. The optical frequencies of the optical spectrum, modulated by the data bits, are then transmitted via a communication section ( ) to an optical receiver ( ) that is coupled to a demodulation section ( ) of the system ( ). Modulated optical frequencies are received as a modulated optical spectrum and demodulated in parallel by an optical demodulator ( ) to derive the data bits.
