 为保障光发射机具有良好的工作环境和稳定的发送光功率,设计完成JAPC和ATC两个电路的应用,在10 GB/s的传输速率下获得良好效果,通过主用与备用设备的交替使用和及时更换LD和 PD元件使光发射机长期稳定可靠工作。随着SDH同步数字传输体系要求的不断提高,光发射机速率的提高成为急需解决的问题,可以使用WDM技术提高传输能力。

Abstract:
 To protect optical transmitter with a good working environment and a stable optical power sent, this paper designed and accomplished the APC and ATC two circuits, which obtained good results in 10GB/s transfer rate. By alternately using main and spare equipment and timely replacing LD and PD devices, the optical transmitter enable to work stably and reliably in a long-term. With the increasing requirements of SDH synchronous digital transmission system, the improvement of the optical transmitter rate becomes an urgent issue,which could use WDM technology to improve transmission capacity.
