    摘要： The invention discloses an optical receiver that prevents the instability of the bias voltage to the avalanche photodiode (APD) and facilitates the recovery of the bias voltage from the safety value. The optical receiver comprises the APD, the DC-DC converter to supply the bias voltage to the APD, the current detector to detect the photo current generated by the APD, and the controller to set the bias voltage. The controller, evaluating the optical input power based on the output voltage of the DC-DC converter and the monitored current, sets the output voltage based on the change of the optical input power.

    摘要： The present invention provides an optical transmitter with a forward controlled Peltier driver. The temperature sensor generates a monitoring signal Sm. The comparator compares this monitored signal Sm with the target temperature signal St to generated the temperature difference signal Sn. The limiter restricts this difference signal Sn between the positive and negative maximum of the periodic signal Sw to generate the limiting signal Sa. The second comparator compares this limiting signal Sa with the periodic signal Sw to generate the control signal. The PWM signal generator, responding to this limiting signal Sa, generates a plurality of PWM signals, Sg1 to Sg4. The H-bridge including four transistors and two inductors, responding to this PWM signals, controls the direction of the current flowing in the Peltier device. The magnitude of the current can be determined by the duty ratio of the PWM signals.

    摘要： A technique is disclosed for an optical transceiver, where the frame ground is electrically isolated from the signal ground in a low frequency region and is conducted in a high frequency region, without applying a capacitor as a substantial circuit component. The transceiver includes a TOSA whose housing is grounded with the FG and connected with the driver with a FPC board. On the FPC board is formed with a parallel plate capacitor, one conductive pattern on the one surface is connected with the housing of the TOSA, while the other pattern in the opposite surface is connected with the SG. This parallel plate capacitor isolates the FG from the SG in low frequencies, while conducts the FG with the SG in high frequencies.

    摘要： The present invention relates to an optical transmitting module that reduces the deviation of the emission wavelength even in a wide range of the operating temperature. The module comprises a laser diode (LD), a Peltier element to control the temperature of the LD, a first sensor to sense the temperature of the LD, a second sensor to sense the ambient temperature, a reference generator, and a Peltier driver. The reference generator, based on the ambient temperature, generates a reference signal to the Peltier drive such that the operating range of the LD becomes smaller than the range of the ambient temperature.

    摘要： The present invention provides an optical module able to reduce the power consumption thereof. The optical module, the package of which has a type of CAN or a co-axial shape, includes a Peltier device, a block, a laser diode (LD) and a photodiode. The block, mounting the LD on the side surface thereof, has a surface for reflecting the light emitted from the light-reflecting facet of the LD, and is mounted on the Peltier device. The photodiode, installed outside the Peltier device, receives the light emitted from the LD and reflected by the surface of the block. Since the photodiode is mounted outside the Peltier device, the cooling efficiency of the Peltier device may be enhanced, which saves the power consumption of the optical module.

    摘要： The present invention provides a light-transmitting module capable of emitting light in stable under a predetermined temperature, especially the light-transmitting module applicable to a condition when the predetermined temperature is lower than ambient temperatures. The light-transmitting module of the present invention includes a light-emitting module, which encloses the laser diode and the Peltier device therein, a substrate electrically connected to the light-emitting module, and a heater. The heater is able to heat the package of the light-emitting module when the predetermined temperature of the laser diode is higher than the ambient temperature, thereby preventing the temperature of the package from lowering the dew-point and droplets from being generated on the substrate. The optical output from the light-transmitting module can be stabled.
