Design and Analysis of the Skikda-Elharrouch Cities Optical Communication Network

Abstract

The most effective solutions available now for information security and protection, industry development, digitization, and operation for future generations are fiber optic networks. In this connection, we used the Optical Reflectometer OTDR to analyze an actual optical link between Skikda-Elharrouche for two different wavelengths offered by "Algeria Telecom". Using the optical simulator OPTISYSTEM, the same network was constructed with the purpose of verifying the optical connection quality by virtual monitoring and cross-referencing with the actual data sheet. The two application wavelengths chosen for the experiment and test were 1310 nm and 1550 nm. By selecting suitable link parameters, we found that the line does not present major defects compared to the results of the OTDR (Optical Time Domain Reflectometer). By simulating the connection in the opposite direction using OptiSystem software, the settings were verified. Results of eye diagrams, the minimum BER (Bit Error Rate) value reaching 2.377 10^-25 for 1550nm and 7.279 10^-45, and quality factor which reaches the value of 10.327 at 1550nm, and the value 14.004 at 1310nm, showed that Skikda-Elharrouche optical link performed better comparing to OTDR results.
