| 简介 |
A multi-stage optical amplifier for a fiber-optic transmission system, in particular, an amplifier having a multi-stage configuration that allows an optimization of its performance with respect to noise, gain and bandwidth. The multi-stage amplifier has a first amplifying stage including a rare-earth doped optical active fiber; a second amplifying stage connected to the first amplifying stage, the second amplifying stage including a tellurite-based active fiber doped with a rare earth element; and a third amplifying stage connected with the second amplifying stage, the third amplifying stage including a silica-based fiber. |
