Description

technical field [0001] The invention relates to the field of electric power communication, and relates to a simulation training device for network modification, optical cable interruption and recovery of electric power communication optical fiber network. Background technique [0002] In the practical training of the existing power communication network element service configuration, it is mainly through the fusion of optical cables to connect different network elements to form a designed network topology. Once the network is completed, the connection status of each network element will change. become difficult. Such as figure 1 As shown in the figure, the trainers conduct service configuration training on the first network element, the second network element, the third network element, the fourth network element, and the fifth network element on the network management software, and set up the services of the entire optical fiber network. The trainers correctly configure A...

[0007] 2) The current simulation process of training in the state of optical cable interruption: if the second optical cable between the first network element and the second network element is simulated to be interrupted, the pigtail can only be unplugged on the optical Remove the first light-emitting interface F1 of the optical distribution frame of the first NE and the first light-receiving interface S1 of the optical distribution frame of the first NE or the first light-emitting interface F3 of the optical distribution frame of the second NE and the optical distribution The first optical receiving interface S3 of the network element at the local end, the trainer uses an optical time domain reflectometer (OTDR) to test the interruption of the optical cable on the optical distribution frame of the local network element, and judges where the breakpoint is, but the training personnel of the opposite network element cannot realize the failure. In the process of finding, it is impossible to complete the current situation where personnel at both ends cooperate to find faults

However, this method cannot realize the fault judgment and repair when the fault occurs in the middle of the optical cable disconnection. (ODF) flanges and pigtails are easily damaged, and the attenuation of the pigtails is too large, so the flanges and pigtails need to be replaced frequently, which causes new problems for fault judgment and repair, and this method of simulating optical cable interruption and repair , cannot achieve the effect of two network element trainers working together to find faults, and cannot truly realize the purpose of training personnel to coordinate troubleshooting and handling faults when an optical cable line fails during production site operation

Therefore, although the existing power communication optical fiber network network change, optical cable interruption and recovery simulation training methods have many advantages and have been applied for many years, due to their performance limitations, it has been difficult to truly The simulated power communication optical fiber network network change, optical cable interruption and recovery simulation training has not been widely used in practical training, which limits the development of training work
