Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] see figure 1 As shown, the present invention provides an optical line protection system integrating an optical time domain reflectometer, including a sending end and a receiving end, and the sending end and the receiving end are connected by an optical fiber for data transmission. The optical line protection unit for optical line switching, when the working line fiber for transmitting service light fails, the optical line protection unit can automatically switch the service light from the main line fiber to the backup line fiber (or from the backup line fiber to the main line fiber) line optical fiber), thereby improving the usability of the optical fiber line and enhancing the reliability of the communication system. The instrument finds the fault point of the fiber by sending scanning light into the fiber, and the scanning light is transmitted toget...

Abstract

The invention discloses an optical link protection system integrated with an optical time domain reflectometer (OTDR), relating to the optical link protection field, and comprises a sending terminal and a receiving terminal which are in connection through fibers, and are both provided with an optical link protection unit used for optical link switching. The optical link protection system is integrated with an OTDR used for finding fiber fault points. The optical link protection system can obtain fiber fault conditions the first time so as to shorten fault treatment time.

Description

technical field [0001] The invention relates to the field of optical line protection in communication networks, in particular to an optical line protection system integrating an optical time domain reflectometer. Background technique [0002] In OTN (Optical Transport Network, Optical Transport Network) and WDM (Wavelength Division Multiplexing, wavelength division multiplexing) networks, each optical fiber carries a large amount of information transmission, such as 80×100G system, once the optical fiber fails, it will bring Therefore, in order to effectively protect the normal transmission of information in optical fibers, optical line protection is widely used in the field of optical transmission. Optical line protection is generally divided into two protection forms: 1+1 and 1:1. [0003] When the optical line protection unit detects a fiber failure, it will switch the light on the main or backup line fiber to ensure the normal transmission of information. At the same tim...
