The ideal candidate will have a strong understanding of fiber-optic technology, network connectivity, testing methodologies, and fault isolation. The candidate will support network installation, configuration, monitoring, troubleshooting, and maintenance activities remotely to ensure reliable network connectivity and optimal performance. Key Responsibilities Monitor, troubleshoot, and support fiber-optic network connectivity and data transmission issues remotely. Diagnose network faults, signal loss, connectivity problems, and fiber-optic link failures. Analyze network performance metrics, alarms, logs, and incident reports. Support fiber-optic infrastructure, including single-mode and multimode fiber systems. Review fiber-optic test results, including Optical Time-Domain Reflectometer (OTDR) traces and optical power measurements. Troubleshoot Layer 1, Layer 2, and basic Layer 3 network connectivity issues. Assist with Ethernet, LAN/WAN, switching, routing, and telecommunications network support. Coordinate with field technicians, network operations teams, and service providers for physical fiber repairs and onsite troubleshooting when required. Perform root-cause analysis and document incident resolutions, recurring faults, and corrective actions. Support network provisioning, circuit testing, service activation, and connectivity validation. Maintain accurate technical documentation, network diagrams, troubleshooting records, and service tickets. Follow established network security policies, operational procedures, and service-level agreements (SLAs). Participate in scheduled maintenance activities, incident escalations, and remote technical support sessions.
