Optical fiber communication experiment box
EQUIPMENTOVERVIEW
The main board and modular structure are adopted, and each module has a standard structure, signal input and output interface, clock bus and communication bus interface. Built-in independent optical power meter and error meter module.
Provide physical protection
The modules have the same size and structure, and the upper and lower layers of protective cover are used to protect the modules in a full range, and the upper layer is a transparent shell for easy observation. In addition, the upper and lower protective shells of the module are connected with bayonets for easy disassembly (screw free installation), which is convenient for experimental teaching and module maintenance.
Self-designed chip protection scheme
The circuit module uses a convenient replaceable pin package bus driver to isolate the I/0 test point of the test circuit and the function chip, which can effectively prevent the wrong operation of the test port connection and the damage of the function chip of the test circuit.
Each module is equipped with an independent power switch
Each module of the experiment box is equipped with an independent multi-channel power switch. Students can turn each module on and off independently according to the actual situation. Each module is relatively independent, which can prolong the product life and improve the reliability of the product.
