Abstract

The invention relates to a wavelength division multiplexing ring loop transferring system automatically controlling device and the controlling method. The device includes light path component section and circuit control section. The light path component section includes the first and the second adjustable attenuator, the first and the second rapid light switch, the first and the second optical splitter and a coupler. The first adjustable attenuator locates at sending end to adjust the light power coming into the ring loop. The second adjustable attenuator adjusts the power of ring loop out end. The first and the second adjustable attenuator connect to the first and the second rapid light switch to adjust the light power. The device and the controlling method solve the automatic control technology problem of ring loop transferring system and ensure the efficiency of the whole test.

Description

Automatic control device and control method for WDM loop transmission system technical field The invention belongs to the technical field of wavelength division multiplexing (WDM) optical transmission in optical fiber communication, and in particular relates to an automatic control device and a control method for a WDM loop transmission system. Background technique With the rapid growth of society's demand for communication, optical fiber communication technology has developed rapidly in recent years. Large-capacity (at least Tb / s) ultra-long-distance (over 2000km without electrical relay) optical transmission system is one of the development directions of optical fiber communication technology. . In the process of developing long-distance and ultra-long transmission systems by various manufacturers, most of them use loop transmission system simulation. The loop transmission system forms a certain length of optical fiber and less amplifiers into a certain length of loop tr...
