    • In a bidirectional optical transmission system between an optical subscriber unit (10; OSU) in a central office and a plurality of optical network units (20A.sub.i ; ONU) in customer premises each coupled with the subscriber unit (10) through an optical fiber cable, the optical subscriber unit (10) has a laser oscillator (11), a device (12) for splitting an output beam of the laser oscillator into n number of beams, a plurality of optical modulators (13-1 through 13-n), coupled with each of the n number of beams, for modulating a related optical beam with a transmission signal S for a respective optical network unit, a plurality of optical detectors (14-1 through 14-n) coupled with each of the optical network units to provide a receive signal R by converting the receive optical signal into electrical form. Each pair of one of the optical modulators and one of the optical detectors are coupled with a respective optical network unit through an optical fiber cable (5-1, 5-2). Each of the optical network units (20-1 through 20-n) has a device for receiving the optical signal from the ONU, to convert the receive optical beam into the electrical signal and for transmitting the optical signal modulated with the transmission signal to the ONU.

    • A vibration isolating apparatus which damps and absorbs vibrations from a vibration generating portion. A first restricting passage, a second restricting passage and a third restricting passage are formed in a block member. Respective transit resistances of these restricting passages are different. One end portion of the first restricting passage is provided so as to be able to communicate with a main liquid chamber, and another end portion communicates with a sub-liquid chamber. One end portion of the second restricting passage is provided so as to be able to communicate with the main liquid chamber, and another end portion has an open portion. One end portion of the third restricting passage communicates with the sub-liquid chamber, and another end portion communicates with the second restricting passage. A rotor is rotated to a first position at which the main liquid chamber and the sub-liquid chamber communicate via the first restricting passage and to a second position at which the second restricting passage communicates with the main liquid chamber. In accordance with the invention, liquid passes through the first, second and third restricting passages, and moves reciprocally between the main liquid chamber and one of the sub-liquid chamber and the second restricting passage in accordance with frequency of vibration. Accordingly, vibrations of a wide range of frequencies can be absorbed.
    • 一种从振动发生部分吸收和吸收振动的隔振装置。 第一限制通道,第二限制通道和第三限制通道形成在块构件中。 这些限制通道的过渡电阻是不同的。 第一限制通道的一端部设置成能够与主液室连通,另一端部与副液室连通。 第二限制通道的一端设置成能够与主液室连通,另一端部具有开口部。 第三限制通路的一端部与副液室连通,另一端部与第二限制通路连通。 转子旋转到主液​​室和副液室通过第一限制通道连通的第一位置和第二限制通道与主液室连通的第二位置。 根据本发明,液体通过第一,第二和第三限制通道,并且根据振动频率在主液室与副液室和第二限制通道中的一个之间往复运动。 因此,可以吸收宽范围的频率的振动。
