    摘要： An electromagnetic wave suppression material is fixed to a case of a communication module. The electromagnetic wave suppression material suppresses radiation of electromagnetic waves by coming into contact with a cage that is a module insertion portion of a chassis when the communication module is inserted into the cage. A piezoelectric element is provided on the case, and located between the case and the electromagnetic wave suppression material. When the communication module is inserted into the cage, the controller applies a voltage to the piezoelectric element to stretch it by the applied voltage, thereby increasing contact pressure between the cage and the electromagnetic wave suppression material.

    摘要： In an optical module in which a transmitter and a receiver that respectively outputs and receives optical signals are stored in a casing, the transmitter and the receiver are connected to a common power line and to a common ground line, and a ferrite bead is arranged on the ground line in the receiver. The ferrite bead absorbs a high-frequency current component out of components in an electric signal passing through the ground line on which the ferrite bead is arranged. An inductance component that evolves on a ground line and a power line of a light receiving element and oscillation of a series resonance circuit that is formed of a capacitance component of the light receiving element are suppressed to reduce crosstalk.
