3BHE018137R0001 光纤中继器 光纤直放站

【产品详情】

光中继器是在长距离的光纤通信系统中补偿光缆线路光信号的损耗和消除信号畸变及噪声影响的设备。是光纤通信设备的一种。其作用是延长通信距离。通常由光接收机、定时判决电路和光发送机三部分及远供电源接收、遥控、遥测等辅助设备组成。光中继器将从光纤中接收到弱光信号经光检测器转换成电信号，再生或放大后，再次激励光源，转换成较强的光信号，送入光纤继续传输。

如果任何单个相电流超过 XU D194 指定跳闸时间的拾取水平，则如果启用该功能，将发生跳闸。

该元素在联机和脱机条件下运行。此元素可用作其他保护装置的备份功能

tion 元素。在发电机并联的情况下，此元件将设置在最大电流以上

安装保护装置的发电机的租金贡献。使用此设置，该元素将提供适当的

选择性跳闸。无延时元件的基本工作时间为 50 ms（50/60 Hz）。

【英文介绍】

Optical repeater is a device that compensates the loss of optical signal and eliminates signal distortion and noise in long distance optical fiber communication system. It is a kind of optical fiber communication equipment. Its function is to extend the communication distance. It is usually composed of optical receiver, timing decision circuit and optical transmitter and auxiliary equipment such as remote power source receiving, remote control and telemetry. The optical repeater converts the weak light signal received from the optical fiber into an electrical signal by the optical detector, and after regeneration or amplification, the light source is stimulated again, converted into a stronger light signal, and is sent to the optical fiber for continued transmission.

If any single phase current exceeds the pick level for the trip time specified by XU D194, a trip will occur if this feature is enabled.

The element runs in both online and offline conditions. This element can be used as a backup function for other protection devices

The tion element. In the case of parallel generators, this element will be set above the maximum current

Rent contribution for generators fitted with protective devices. With this setting, the element will provide the appropriate

Selective tripping. The basic operating time of the delay-free element is 50 ms (50/60 Hz).
