Abstract: A network switch device and an operating method therefor are provided. The method includes: receiving, by a logic unit, a plurality of interrupt control signals from a plurality of optical fiber data transceivers, where each of the interrupt control signals reflects whether an operating state of each of the optical fiber data transceivers becomes anomalous or changes; combining, by the logic unit, the interrupt control signals from the optical fiber data transceivers into an interrupt combined signal; receiving, by an interrupt control pin of a processing unit, the interrupt combined signal; determining, by the processing unit, whether a logic level of the interrupt combined signal changes; and if the processing unit determines that the logic level of the interrupt combined signal changes, executing, by the processing unit, an interrupt handler, and determining which one of the optical fiber data transceivers becomes anomalous or changes.
