    摘要： An optical transmitter receiver module and an apparatus incorporating the same module are provided, which realizes the reduction of power consumption and the enlargement of the operating temperature range. As an example, an optical transmitter module is provided which comprises a light emitting element to generate a light signal, a signal processing circuit to transmit an electrical signal to the light emitting element and a voltage regulating circuit to lower a power voltage so as to supply the signal processing circuit with a constant voltage, wherein the module is further provided with a current regulating circuit to shunt a part of a current to be supplied into the voltage regulating circuit from a power source so as to generate a control current and a temperature controller to receive the control current so as to control a temperature of the light emitting element, wherein the module is further provided with a temperature detector to detect the temperature of the light emitting element and a temperature controlling circuit to control the control current according to an electrical signal output by the temperature detector.

    摘要： An optical transceiver has a projection covering member that can suppress EMI noise radiated from a pig-tail part. An elastic covering member covers a projection which includes an optical coupler of an optical sub assembly. The covering member is made of a conductive elastic material having a predetermined resistivity. At least a part of an outer circumference surface of the elastic covering member comes into intimate contact with an outer periphery of a conductive opening part of a case for the optical transceiver while an inner circumference surface of the elastic covering member comes into intimate contact with the projection.

    摘要： An optical module includes an electromagnetic wave absorption member. The electric connection member includes a floating portion which is in a floating state spaced apart from the housing and at a position away from a mounting portion by which the electric connection member is mounted on the housing in the direction opposite to the direction that the optical module is inserted into a cage. At least a portion of the electromagnetic wave absorption member is arranged between the housing and the floating portion. The floating portion is brought into contact with an inner side of the cage so as to establish the electrical connection with the inner side of the cage when the housing is inserted into the cage.
