Fusion Splice Monitoring Installation Guide117

Introduction

Fusion splice monitoring is a crucial aspect of ensuring the reliability and performance of fiber optic networks. This guide will provide step-by-step instructions on how to properly install a fusion splice monitoring system, ensuring accurate and continuous monitoring of splice joints.

Equipment Required

To install a fusion splice monitoring system, you will need the following equipment:* Optical spectrum analyzer (OSA)
* Optical fiber identifier (OFI)
* Optical fiber fusion splicer
* Cleaver
* Stripper
* Isopropyl alcohol
* Lint-free wipes

Pre-Installation Considerations

Before installing the monitoring system, ensure the following:* The splice location is clean and free from debris.
* The fiber cables are properly prepared and cleaved.
* The fusion splicer is properly calibrated.

Monitoring Point Selection

The monitoring point should be located at a suitable location along the splice joint. Consider the following factors:* Accessibility for regular monitoring and maintenance.
* Away from potential sources of vibration or interference.
* Optimal distance from the fusion splice (typically 5-10 cm).

Mounting the Monitoring System

Install the OSA and OFI at the designated monitoring point. Secure them using appropriate mounting hardware or adhesives.

Connecting the Fibers

Connect the input and output fibers of the fusion splice to the OSA and OFI ports, respectively. Ensure a proper connection and use fiber optic connectors with low insertion loss.

Powering the Equipment

Connect the power supply to both the OSA and OFI. Power on the equipment and allow it to initialize.

Configuring the Monitoring Software

Configure the monitoring software according to the manufacturer's instructions. Typically, this involves setting up alarm thresholds, monitoring intervals, and data storage parameters.

Setting Alarm Thresholds

Set alarm thresholds for the monitored parameters, such as optical power loss and optical return loss. These thresholds will trigger alerts in case of any significant changes in the splice performance.

Testing the Monitoring System

To test the monitoring system, perform the following steps:* Generate a known optical signal using an optical source.
* Connect the optical source to the input port of the monitoring system.
* Verify the signal level and quality using the OSA and OFI.
* Connect a loopback connector to the output port of the monitoring system.
* Monitor the signal level and quality to ensure proper signal return.

Maintenance and Troubleshooting

Regularly monitor the monitoring system for any anomalies or alarms. Clean the optical connections and inspect the fibers for any damage or contamination. If any issues arise, refer to the manufacturer's documentation for troubleshooting steps.

Conclusion

Following these instructions will ensure the successful installation and operation of a fusion splice monitoring system. This will enable continuous monitoring of critical fiber optic splices, enhancing the reliability and performance of the overall network.
