光旁路技术研究及应用

Research on Optical Bypass Technology and Its Application

光旁路技术是行业的新兴技术,尤其适用于链形及环形网络结构。当处于链形网络中间的某一传输设备因停电停止工作后,光旁路设备会立即切换光路,将该站上游过来的光信号跳过本站,直接送至下游站,从而避免了下游站业务中断。它具有非常积极的学术研究价值及市场价值。

Optical bypass technology is emerging in telecommunication industry, especially suitable for the chain or ring network structure. When a transmission device in the middle of a chain network stops working for power failure, optical by- pass device will take effect at once. It skips this station and directly sends signal from the upstream to the downstream. And by this way, it effectively keeps all the downstream equipments from running stop. So it is quite meaningful for academic re- search and market development.
