Abstract: New method to control the optical transmitter is disclosed. The optical transmitter provides both of the ATC feedback loop and the APC feedback loop. When a failure occurs in the ATC feedback loop and the temperature sensor is unable to output an adequate signal any longer, the optical transmitter cuts the APC loop and operates the LD in constant conditions. The output of the monitor PD is transferred to the ATC loop to control the TEC based on the optical output of the LD.

Abstract: There is provided a wireless LAN access point capable of confirming and changing the setting using the IP communication for a target wireless LAN access point positively even when the IP address of the wireless LAN access point is forgotten. The wireless LAN access point, upon receipt of a probe request, transmits a probe response while at the same time starting to transmit a beacon frame required to be periodically transmitted. The wireless LAN access point starts the DHCP server therein at the same time that the process of associating the wireless LAN station is started. The DHCP server operates only for the wireless interface of the wireless LAN access point and the wireless LAN station associated by use of the maintenance SSID. The wireless LAN access point, upon complete association of the wireless LAN station with the local access point, leases the IP address to the wireless LAN station from the DHCP server in the particular local access point.

Abstract: A control circuit for a laser diode is disclosed, in which the driving current may be suppressed even when the monitor PD breaks down to make the APC feedback control inoperable. The control circuit comprises an LD driver to supply the driving current to the LD, a monitor PD to detect a portion of output light from the LD, and the APC controller to adjust the driving current. The current limiter, when the driving current reaches or exceeds the threshold, controls the driving current Id so as to keep the current in a preset value or a value just before the extraordinary increase of the driving current occurs.

These data are stored into a plurality of memories and at the same time a decision section decides the transmission rate. A switch section reads data from one of the memories selected according to the result of the decision.

Abstract: An optical transmitter is disclosed. The transmitter provides, in addition to a semiconductor laser diode as a light source, a variable polarizer with a Farady rotator and a polarization analyzer on an optical path of the laser diode. When the wavelength of the emitted light from the laser diode shifts, by adjusting the rotation angle of the Farady rotator by the current supplied to the coil so as to align the rotation angle with the polarization plane of the polarization analyzer, the wavelength shift of the laser diode may be estimated. Also, by comparing the optical magnitude between the initial of the operation and after the long-time operation at the output from the polarization analyzer after the alignment of the rotation angle of the Farady rotator, the degradation of the laser diode is detected.

Abstract: The present invention provides an optical receiver in which a signal detection level is independent on whether a ammeter is connected to a current monitor terminal or not. The optical receiver comprises a photo diode, a first current mirror circuit connected to the photo diode and a second current mirror circuit. The second current mirror circuit has a pair of current path, one of which is connected to the first current mirror circuit and the other of which is connected to the voltage source provided within the optical receiver. The voltage source supplies a bias whether an ammeter is connected to the other of the current path or not. Therefore, the signal detection level attributed to one of the current path is unchanged.
