    • A transmission line monitoring apparatus includes a first optical coupling unit, a first optical dividing unit, a second optical coupling unit, a second optical dividing unit and a monitoring unit. The first optical coupling unit couples a down data signal with a first wavelength and an examination signal with a second wavelength into a first coupled signal. The first optical dividing unit receives the first coupled signal and divides the first coupled signal into the down data signal with the first wavelength and the examination signal with the second wavelength. The second optical coupling unit couples an up data signal with the first wavelength and the examination signal from the first optical dividing unit into a second coupled signal. The second optical dividing unit receives the second coupled signal and divides the second coupled signal into the up data signal with the first wavelength and the examination signal with the second wavelength. The monitoring unit monitors a fault and a position of the fault.
    • 传输线监视装置包括第一光耦合单元,第一光分路单元,第二光耦合单元,第二光分路单元和监视单元。 第一光耦合单元将具有第一波长的下数据信号和具有第二波长的检测信号耦合到第一耦合信号中。 第一光分割单元接收第一耦合信号,并将第一耦合信号分成具有第一波长的下降数据信号和具有第二波长的检测信号。 第二光耦合单元将来自第一光分路单元的上升数据信号与第一波长和检查信号耦合到第二耦合信号。 第二光分割单元接收第二耦合信号,并将第二耦合信号分成第一波长的上行数据信号和具有第二波长的检查信号。 监控单元监视故障和故障位置。

    • A plug body is adapted to be fitted into a socket body in a first direction, and formed with a groove extending in a second direction perpendicular to the first direction. Each of plug contacts has a first contact piece and a second contact piece opposing to each other with a gap therebetween. The plug contacts are arrayed such that the first contact piece and the second contact piece are disposed in the groove. Each of projections is extended from the first contact piece so as to oppose the second contact piece, and is formed with a slant face so that a thickness thereof is reduced toward a distal end thereof. The slant faces of the projections form V-shaped lines when the projections are viewed from the first direction.
    • 插头本体适于沿第一方向装配到插座主体中,并且形成有沿垂直于第一方向的第二方向延伸的凹槽。 每个插头触点具有彼此相对的第一接触片和第二接触片,其间具有间隙。 插头触点排列成使得第一接触片和第二接触片设置在凹槽中。 每个突起从第一接触片延伸以与第二接触片相对,并且形成有倾斜面,使得其厚度朝向其远端减小。 当从第一方向观察突起时,突起的倾斜面形成V形线。
