Fiber Technician

We are seeking elite Lead Fiber Audit & Optical Network Validation Technicians to support large-scale hyperscale and carrier-grade data center environments. This role is responsible for auditing, validating, troubleshooting, and restoring mission-critical fiber infrastructure supporting high-capacity optical transport networks, DWDM systems, cloud platforms, and ultra-low latency services. This is a senior-level, hands‑on position requiring deep expertise in fiber optics, optical transport fundamentals, circuit validation, contamination analysis, OTDR interpretation, and fault isolation. Successful candidates must demonstrate the ability to identify, troubleshoot, and remediate fiber impairments with minimal supervision while maintaining exceptional documentation accuracy. Candidates should understand that a single contaminated fiber connection can impact multi-million-dollar DWDM transport systems, cloud workloads, customer traffic, and critical network services. Precision, discipline, and technical ownership are mandatory. About the Role This role is responsible for auditing, validating, troubleshooting, and restoring mission-critical fiber infrastructure supporting high-capacity optical transport networks, DWDM systems, cloud platforms, and ultra-low latency services. Responsibilities Perform high-volume end-to-end fiber circuit audits across multiple active DMARC, MMR, and data center environments during a single shift. Validate optical paths supporting DWDM, transport, backbone, cloud, and mission-critical network infrastructure. Inspect, clean, scope, test, document, and certify fiber circuits using industry-standard testing methodologies and cleanliness standards. Conduct optical power measurements utilizing calibrated light sources and power meters at 1310nm and 1550nm wavelengths. Interpret optical power readings and identify abnormal loss conditions, excessive attenuation, polarity issues, contamination events, and potential physical damage. Perform OTDR testing and analysis to identify fiber faults, splice loss, connector defects, reflection events, macro bends, micro bends, and distance-to-fault locations. Troubleshoot failed optical circuits and isolate fault domains within patch panels, cross-connects, DMARC facilities, transport paths, and customer infrastructure. Differentiating contamination-related failures from permanent connector, ferrule, or fiber damage and determine appropriate remediation actions. Inspect MPO/MTP, LC, and SC connectors and validate compliance with fiber cleanliness standards and optical performance requirements. Escalate unresolved transport, optical, or physical layer issues using established operational procedures and technical reporting standards. Qualifications Minimum 3+ years of hands‑on fiber optics experience within data centers, carrier facilities, colocation environments, central offices, network rooms, or mission‑critical infrastructure. Demonstrated experience supporting high-density optical environments utilizing LC, MPO/MTP, and SC connectivity. Experience performing fiber audits, circuit certification, infrastructure validation, or transport network commissioning activities. Strong understanding of DMARC, Meet‑Me Room (MMR), and carrier interconnection environments. Ability to independently identify contamination, connector defects, ferrule damage, fiber damage, and optical loss events. Required Skills Expert-level proficiency with fiber inspection scopes and video probe systems. Experience interpreting optical power readings and understanding acceptable loss budgets for both single-mode and multimode environments. Working knowledge of IEC 61300-3-35 fiber cleanliness standards. Ability to accurately inspect MPO connectors across all fiber positions and interpret pass/fail criteria. Experience conducting insertion loss testing and circuit certification activities. Ability to understand and evaluate optical network performance using measurable test data. Preferred Skills Hands‑on OTDR testing experience at 1310nm and 1550nm wavelengths. Ability to read and interpret OTDR traces and event tables. Experience locating fiber faults, reflective events, splice issues, connector defects, and attenuation anomalies. Ability to isolate failures to specific network segments and determine corrective actions. Proven history of resolving optical failures during initial troubleshooting efforts. Experience supporting transport, DWDM, metro, backbone, carrier, or cloud network infrastructure strongly preferred. #J-18808-Ljbffr
