A teaching experiment box based for a passive optical fiber communication principle

Abstract

The invention discloses a teaching experiment box based for a passive optical fiber communication principle, which comprises a main box body and a cover plate for covering the main box body. The optical module assembly embedded in the main housing comprises a G. 652 standard single-mode optical fiber, a G.655 standard single-mode optical fiber, a multimode optical fiber, an SC / FC connector, a variable optical attenuator, a 1:4 beam splitter, a multiplexer, a demultiplexer, an optical isolator, a light source module and an optical power meter. The panel of the main cabinet is divided into fourfunctional areas, an optical fiber testing functional area, an optical passive device testing functional area, an accessory and consumable placement area and a transmitting and receiving area. Modulardesign and project distribution are reasonable, the test box layout in the test function area strives for the least instrumentation, realizing the reasonable layout of short connection lines, fewer adapters and combination. The platform of the experiment box is easy to operate, has many items and covers many knowledge points. One experiment box can do many experiments, which has high integrationand low cost.

Description

technical field [0001] The invention relates to a teaching experiment box for the principle of passive optical fiber communication. Background technique [0002] Optical fiber communication uses light as the carrier, optical fiber as the transmission medium, and a communication system in which optical transceivers use light to transmit information. In the 21st century, optical fiber communication has become the most important strategic industry. The main medium, optical communication system and passive devices in the optical fiber communication system are particularly important. The teacher explains the composition, performance and characteristics of the transmission medium optical fiber and optical passive devices. It is not easy for students to understand and remember. In order to strengthen students' ability to quickly and A deep grasp of this part of knowledge requires experimental teaching. However, the current optical fiber communication principle or system experimen...
