Core Responsibilities

Primary Functions

Perform precision fusion splicing on singlemode and multimode fiber optic cables, producing low-loss, end-to-end splices that meet project and industry loss specifications; inspect and document each splice using OTDR and power meter readings.
Execute mechanical splices and specialty splicing techniques for temporary repairs or where fusion splicing is not suitable, ensuring mechanical integrity and signal continuity.
Prepare and terminate fiber optic cables: stripping jackets, cleaning fibers, cleaving, aligning, and installing heat-shrink boots, splice protectors, and splice trays to manufacturer and company standards.
Install and secure splice closures, handholes, vaults and enclosures in aerial, underground, and indoor environments; ensure seals are watertight and closures are properly labeled and documented.
Troubleshoot, locate, and repair fiber faults using OTDR, Visual Fault Locator (VFL), power meters, continuity testers and specialized fault-locating equipment; produce OTDR traces and interpret results to pinpoint issues.
Perform cable pulling, blowing, and placement operations in conduit, innerduct and aerial messenger systems; calculate tension, bend radius and fill for safe installation and long-term performance.
Conduct acceptance and certification testing for newly spliced fiber links (OTDR traces, insertion loss, return loss) and submit formal test reports and acceptance documentation to project managers and customers.
Respond to emergency outages and service restorations 24/7 when required; perform expedited splicing, temporary repairs and full restoration while maintaining safety and network integrity.
Read and interpret network drawings, schematics, splice maps, blueprints and as-built plans to determine splice locations, fiber counts, and routing; update drawings and GIS records after work completion.
Maintain, calibrate and operate fusion splicers, OTDRs, power meters, cleavers, microscopes and other specialized tools; perform daily pre-shift equipment checks and troubleshoot tool malfunctions.
Execute aerial splicing operations including pole climbs and use of bucket trucks or lifts; install and secure aerial cables, messenger wires, and attachments per NESC and company standards.
Perform underground splicing in manholes and vaults, including confined space entry procedures when necessary, and adhere to all confined space and excavation safety protocols.
Perform armored cable cutting and preparation, jacket restoration and sheath repair for long-haul and specialty cable types while maintaining fiber integrity.
Complete accurate, time-stamped splice records, OTDR traces, loss logs and material consumption reports in company systems (paper and digital) to support warranty, billing and maintenance workflows.
Coordinate with civil crews, project managers, traffic control and local authorities to schedule safe work windows for roadway or right-of-way splicing activities; install traffic control when required.
Train and mentor apprentices and junior technicians on best practices for splicing, testing, safety and documentation; provide on-the-job coaching to improve team productivity and quality.
Enforce and follow safety protocols, PPE usage, fall protection, bucket truck operation best practices and lockout/tagout procedures to ensure zero-harm field operations.
Manage spare parts, consumables and field inventory: maintain stock of splice protectors, closures, connectors, cleaning supplies and fusion splicer consumables; report shortages and reorder as needed.
Implement quality assurance checks and follow project-specific acceptance criteria; participate in post-installation audits and remediate any deficiencies identified.
Collaborate with project managers, engineers and customer stakeholders to review scope, identify sequence of splicing work, resource needs and estimated durations; provide field feedback that improves design and scheduling.
Support commissioning activities for PON/FTTx and backbone networks, including splitters, muxes and OLT/ONT handoffs; validate pass/fail acceptance criteria and troubleshoot end-to-end service issues.
Apply industry standards and regulatory compliance requirements (NESC, OSHA, NFPA, manufacturer specs) to all splicing and installation activities, maintaining certification and documentation.
Maintain situational awareness of environmental risks (wildlife, weather, excavations) and implement mitigation to protect personnel and network assets.

Secondary Functions

Assist in preparing project estimates, timecards, material take-offs and daily progress reports to support field operations and billing.
Participate in continuous improvement initiatives: recommend tooling, process or workflow changes that reduce splice time, improve quality or lower material waste.
Support customer-facing activities including site walks, status updates and technical explanations of splicing/testing results in clear, non-technical language.
Serve as an escalation resource for complex field faults and collaborate with NOC/engineering teams to identify root causes and permanent fixes.
Contribute to safety meetings, tool-box talks and training sessions; help develop practical field training materials and checklists for splicing and testing.
