Three-network integrated comprehensive practical training device

Abstract

The invention provides a three-network integrated comprehensive practical training device. The three-network integrated comprehensive practical training device comprises a network system and a comprehensive testing desk, wherein the network system comprises a core layer device, a transmission access layer device and a terminal device; the core layer device comprises a network core device, a management server and a business subsystem; the network core device comprises a three-layer switch and a two-layer switch; the business subsystem comprises a streaming media server, an optical transmitter, an optical attenuator, an optical amplifier, an IP voice exchanger, an IP satellite receiver and an IP encoder; the transmission access layer device comprises a GPON device, an Ethernet passive optical network (EPON) device, a wavelength division multiplexer, an optical branching device, an optical network base station and an optical network unit; the terminal device comprises a television, a set top box, an EOC terminal, a twin-fiber transceiver terminal, a computer and a telephone. For the practical training device, interfaces of the devices are reserved at the comprehensive testing desk, so that the wiring networking training can be conveniently carried out during the practical training process, the practical training difficulty is reduced, and the practical training demand is satisfied.

Description

technical field [0001] The invention relates to a network practical training teaching device, in particular to a triple network fusion comprehensive practical training device. Background technique [0002] The integration of the three networks means that in the process of the evolution of the telecommunication network, radio and television network, and the Internet to the broadband communication network, digital TV network, and next-generation Internet, the three major networks will undergo technological transformation, and their technical functions will tend to be consistent, and their business scope will tend to be the same. Network interconnection and resource sharing can provide users with various services such as voice, data and broadcasting and television. my country's cable television system is developed on the basis of shared antennas. [0003] From the perspective of technology, the rapid development and comprehensive adoption of digital technology enables telephon...
