Embodiment 1

[0031] Example 1, such as figure 1 As shown, the device body includes SDH ring network main optical fiber link and SDH ring network backup optical fiber link, SDH ring network master node (1) and SDH ring network slave node (2). The SDH ring network topology is a two-fiber unidirectional channel protection ring structure. The protection ring consists of active optical fiber links and backup optical fiber links. Both the main optical fiber link of the SDH ring network and the standby optical fiber link of the SDH ring network are step-type single-mode optical fibers. In order to show the SDH ring network to the students, the length of the two optical fiber links is 20Km. Transmission does not require relaying.

[0032]SDH ring network main optical fiber links include bare fiber A (4), bare fiber B (8), fault point device (6) and jumper A (3), jumper B (5), jumper C (7) and Jumper D (9). The bare fiber A (4) is connected to the fault point device (6) through the jumper fiber...

Abstract

The invention provides an SDH ring network transmission optical fiber link construction maintenance teaching device comprising an SDH ring network main optical fiber link, an SDH ring network backup optical fiber link, an SDH ring network master node and an SDH ring network slave node. The SDH ring network main optical fiber link and the SDH ring network backup optical fiber link form an SDH ringnetwork topology structure. The SDH ring network topology structure is a two-fiber one-way channel protection ring structure, and the optical fibers in the SDH ring network main optical fiber link andthe SDH ring network backup optical fiber link are the step type single mode optical fibers. The SDH ring network topology can be visually displayed to the students through flexible configuration. The students can transmit different power and wavelengths of optical signals to the SDH network by setting the light source parameters so that the practical operation, analysis and computation abilitiesof the students in the SDH ring network optical fiber link construction maintenance can be strengthened through actual measurement numerical analysis and computation.

Description

technical field [0001] The invention belongs to the technical field of teaching and training equipment, and relates to an SDH ring network transmission optical fiber link construction maintenance teaching device and a use method. Background technique [0002] The SDH (Synchronous Digital Hierarchy) transmission ring network can realize flexible service allocation, is suitable for network transmission between points, has certain network protection functions, and has a wide range of applications in the field of rail transit. In the construction process of the optical fiber SDH ring network, the length of the optical fiber, the attenuation of the optical fiber, the average attenuation of the optical fiber, and the obstacles of the optical fiber have a great influence on the transmission of optical signals. [0003] When the trainees were learning the SDH ring network, although they understood the SDH topology diagram and the optical fiber construction process, due to the long d...
