Abstract
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.
Highlights
The market for optical networks has grown by diversifying the routes of optical fiber communication
We developed a handheld line information reader and line information generator to detect faulty lines and manage optical networks in online and offline modes
When the radiation field radiates by bends in the fiber lines, the modulated signals of the radiation field are detected by the line information reader
Summary
The market for optical networks has grown by diversifying the routes of optical fiber communication. The capacity of commercial light-wave systems increased from roughly (FTTH) and have started to use optical fiber networks such as active optical networks (AONs) or passive optical networks (PONs) [7,8,9,10]. The FTTH application has increased because of the growth of Internet subscribers [11]. The application of wavelength division multiplexing (WDM) has affected the growth of optical networks [12,13,14]. WDM can use multiplexing technology in optical communication networks [15], and monitoring of linear and non-linear signals distortion are studied for more efficient and reliable optical network performances [16,17,18]
