    • An optical fiber characteristic measuring device for automatically measuring, at successive measuring stages, various characteristics of optical fiber samples. Each measuring stage has optical system incident and emergent ends. An optical fiber sample is set in a carrier which moves from measuring stage to measuring stage. At each stage the set fiber sample is coupled to the incident and emergent ends of the stage and automatically subjected to the measurement to which the stage is dedicated. Bending units provide a desired degree of curvature to the fiber sample under test to control light propagation therein.
    • 一种光纤特性测量装置,用于在连续的测量阶段自动测量光纤样品的各种特性。 每个测量台都有光学系统入射和紧急端。 将光纤样品放置在从测量级移动到测量级的载体中。 在每个阶段,设定的光纤样品耦合到舞台的入射端和紧急端,并自动进行舞台专用的测量。 弯曲单元为被测纤维样品提供所需的曲率,以控制其中的光传播。

    • To provide a data transmitting apparatus and the like capable of enhancing error detection accuracy without increasing a bandwidth unnecessarily used for the error detection performed on encrypted data and minimizing deterioration in sound quality of the data by effectively reducing noises in the transmission of the data through networks for cars and the like even though the data transmitting apparatus has been simply structured. The present invention makes it possible to perform error detection on audio data according to the sizes of encrypted blocks or packets using simple error check codes embedded in the audio data, or to perform error detection using a variation sequence of attribute information to be transmitted together with the audio data. In this case, output of the sound resulting from the audio data having an error is stopped.
