    摘要： In controlling a discrimination level V.sub.1, V.sub.1 is controlled so that discrimination results based on discrimination levels V.sub.1 +.DELTA.V and V.sub.1 -.DELTA.V each become equal to the discrimination result based on the discrimination level V.sub.1. If the discrimination result based on V.sub.1 +.DELTA.V does not agree with the discrimination result based on V.sub.1, V.sub.1 is lowered, and if the discrimination result based on V.sub.1 -.DELTA.V does not agree with the discrimination result based on V.sub.1, V.sub.1 is raised. In controlling a discrimination phase .PHI..sub.1, .PHI..sub.1 is controlled so that discrimination results based on discrimination phases .PHI..sub.1 +.DELTA..PHI. and .PHI..sub.1 -.DELTA..PHI. each become equal to the discrimination result based on the discrimination phase .PHI..sub.1. If the discrimination result based on .PHI..sub.1 +.DELTA..PHI. does not agree with the discrimination result based on .PHI..sub.1, .PHI..sub.1 is delayed, and if the discrimination result based on .PHI..sub.1 -.DELTA..PHI. does not agree with the discrimination result based on .PHI..sub.1, .PHI..sub.1 is advanced.

    摘要翻译： 在控制识别电平V1时，V1被控制，使得基于识别电平V1 + DELTA V和V1- DELTA V的辨别结果分别基于鉴别电平V1等于鉴别结果。 如果基于V1 + DELTA V的识别结果与基于V1的识别结果不一致，则V1降低，并且如果基于V1-DELTA V的识别结果与基于V1的识别结果不一致，则V1增加。 在控制鉴别阶段PHI 1时，控制PHI 1，使得基于鉴别阶段PHI 1+ DELTA PHI和PHI 1- DELTA PHI的辨别结果分别基于鉴别阶段PHI 1等于鉴别结果。如果鉴别结果 基于PHI 1+ DELTA PHI与基于PHI 1的鉴别结果不一致，PHI 1被延迟，并且如果基于PHI 1- DELTA PHI的判别结果与基于PHI 1的鉴别结果不一致，则PHI 1 是先进的

    摘要： A module is configured to be attached to a cage. A handle is rotatable about a rotation shaft between an accommodated position where the module is mounted to the cage and a withdrawal position where the module can be withdrawn from the cage. A resiliently-bendable tongue piece performs engagement and disengagement between the module and the cage. A notch portion is provided to the tongue piece. A press portion is provided to the handle on a circumference having a center located on the rotation shaft of the handle, the press portion configured to contact with the notch portion when the handle is at the accommodated position. A cam rotatable with the handle so as to resiliently bend the tongue piece.

    摘要： An optical transmitter comprises a first unit for generating an optical signal having a bandwidth given by a main signal, a second unit modulating the optical signal according to a control signal to extend the bandwidth of the optical signal, a third unit extracting backward light including SBS(stimulated Brillouin scattering) light generated in an optical fiber transmission line, and a fourth unit performing feedback control so that the power of the SBS light becomes substantially constant. Through the structure of the optical transmitter good transmission characteristics of a main signal are obtained and the suppression of the SBS is allowed.

The optical module includes a threshold calculation unit that calculates the threshold value based on the electric signal from the optical reception unit and a signal path characteristic of the reception signal path from the optical reception unit to the identification unit, and the identification unit of the processing unit performs the identification processing based on the threshold value calculated by the threshold calculation unit. Thereby, the threshold value is optimized when the identifier is provided in the unit as a connection destination of the optical module.

    摘要： According to an optical-receiving apparatus including an APD converting input light into an electric signal and a bias-voltage-control method used for the optical-receiving apparatus, a multiplication factor appropriate for the APD is predetermined and a multiplication factor used for the APD can be maintained at the level of the predetermined multiplication factor at all times according to a change in the ambient temperature of the APD so that the intensity of input light-transmitted to the APD can be monitored with accuracy. The optical-receiving apparatus further includes a bias circuit generating a bias voltage applied to the APD based on a control signal, a temperature-monitor circuit monitoring the ambient temperature, and an operating circuit that stores data on the predetermined multiplication factor and that controls the bias circuit so that the multiplication factor corresponding to the monitored temperature becomes the predetermined multiplication factor.
