32 CHAPTER 5 CONCLUSION 5.1 Conclusion The conclusion of the project's capabilities as a result of the combination of hardware and software used in this project will be able to notify the user of the damage to the critical optical line immediately, which will eliminate the need for the user to call the operator and wait a long time for the technical team to come and repair the line. The repair team will take around 24 hours to arrive. The technical staff will be able to monitor the line's health using an application connected to the device installed in the fiber optic box, which will further ensure the line's stability. It can see cable power in dBm that complies with minimum standards of 25 dBm. This project may also reduce the cost of fault repair and the downtime of optical lines. The technical team can receive early alerts by utilizing the Blynk IoT application. Thus, in the event that an optical fiber is damaged, the team will be notified through mobile phone. As a result, the chance of extensive damage to the line is decreased because the Technical Team can respond promptly to any possible issues.. The integration of hardware and software components also provides a seamless experience for the user, as all the information is available in one place and can be easily accessed through the application. Furthermore, the project has the potential to increase overall network performance by minimizing outages for 24 hours and enhancing optical line stability. Overall, the combination of hardware and software in this project provides a comprehensive solution for reducing the report from customers everyday example: 50 reports to 30 reports per day also technical team can monitor and maintain the health of the critical optical line.
