摘要： There is provided a PD-TIA module that can be used for recognition of an address of an optical packet signal in a system having variation in mark rate all the time, such as an optical packet communication system. An optical communication module comprises a photoelectric converter for converting an optical signal into a current signal, a current/voltage conversion means connected to the photoelectric converter, for converting the current signal into a voltage signal, and a limiting amplifier for receiving and amplifying an electric signal subjected to voltage conversion by the current/voltage conversion means while comparing the electric signal as amplified with a predetermined threshold value, thereby outputting a signal for “0” or “1”.

摘要： An address recognition apparatus may include a first normalizing unit, a second normalizing unit and an address determination unit. The first normalizing unit normalizes a first electric signal and generates a first normalized signal, wherein the first electric signal is associated with a first divided set of optical packet signals. The second normalizing unit normalizes a second electric signal and generates a second normalized signal, wherein the second electric signal is associated with a second divided set of optical packet signals. The address determination unit refers to the first and second normalized signals and determines whether a destination address of a set of optical packet signals is identical to or different from an address allocated to a self-station associated with the address recognition apparatus, wherein the set of optical packet signals has been divided into the first and second divided sets of optical packet signals.
