A handheld line information reader and a line information generator were developed for the efficient management of optical communication lines. The line information reader consists of a photo diode, trans-impedance amplifier, voltage amplifier, microcontroller unit, display panel, and communication modules. The line information generator consists of a laser diode, laser driving circuits, microcontroller unit, and communication modules. The line information reader can detect the optical radiation field of the test line by bending the optical fiber. To enhance the sensitivity of the line information reader, an additional lens was used with a focal length of 4.51 mm. Moreover, the simulation results obtained through BeamPROP software from Synopsys, Inc. demonstrated a stronger optical radiation field of the fiber due to a longer transmission wavelength and larger bending angle of the fiber. Therefore, the developed devices can be considered as useful tools for the efficient management of optical communication lines.
为了高效管理光通信线路，开发了一种手持式线路信息读取器和一种线路信息生成器。线路信息读取器由光电二极管、跨阻放大器、电压放大器、微控制器单元、显示面板和通信模块组成。线路信息生成器由激光二极管、激光驱动电路、微控制器单元和通信模块组成。线路信息读取器可以通过弯曲光纤来检测测试线路的光辐射场。为了提高线路信息读取器的灵敏度，使用了一个焦距为4.51毫米的附加透镜。此外，通过Synopsys公司的BeamPROP软件获得的模拟结果表明，由于光纤的传输波长更长和弯曲角度更大，光纤的光辐射场更强。因此，所开发的设备可被视为高效管理光通信线路的有用工具。
