摘要： A light source supplies optical signal to an optical switch and a detector detects light receiving level. A control unit changes a deflection control amount for changing an angle of a tilt mirror, and outputs the deflection control amount to a driving unit. When an input and an output ports are same, optical offset of the tilt mirror is calculated based on optimal angle at which the light detector detects an optimal point of the light receiving level. Whenever the input and the output port are different, a structure parameter of the tilt mirror is calculated based on the optical offset and the optimal angle. The optical offset and the structure parameter are stored in a memory as a test result.

The fixed-length cell receiving unit is coupled through an optical transmission line to the fixed-length cell transmitting unit and is equipped with a plurality of optical receiving sections for converting a fixed-length cell of an optical signal into an electric signal and outputting the converted electric signal. In addition, the fixed-length cell receiving unit drives the optical receiving section corresponding to the optical transmitting section to be put to use in the fixed-length cell transmitting unit. The optical transmitting section and the optical receiving section are determined in accordance with the operating band at the transmission.

To realize this object, the transmission apparatus includes a determining unit that determines, when a transmission apparatus receives a frame from each ring in a network including multiple rings in which a part of each ring is shared, whether failure information indicating that a failure has occurred in one of the rings is contained in one of the received frames. The transmission apparatus also includes a mapping unit that maps a frame that is determined by the determining unit to contain the failure information, onto a shared frame that is a frame used in a shared portion in the multiple rings. Accordingly, the process performed due to a failure recovery can be simplified.
