Core Responsibilities

Primary Functions

Perform high-precision fusion and mechanical splicing on a variety of single-mode and multi-mode fiber optic cables in both outdoor and indoor environments, including aerial, underground, and customer premise locations.
Construct and configure splice closures (enclosures) and distribution panels, meticulously routing and organizing fibers within splice trays according to detailed engineering schematics.
Utilize advanced diagnostic equipment, including Optical Time-Domain Reflectometers (OTDR) and Power Meters, to conduct comprehensive testing, certification, and fault location on new and existing fiber optic links.
Interpret OTDR trace results to accurately identify and diagnose issues such as macrobends, microbends, bad splices, or fiber breaks, and execute precise repairs to restore service.
Read and precisely interpret complex network design maps, splice diagrams, blueprints, and as-built drawings to ensure accurate fiber placement, connections, and network construction.
Perform ring cuts, mid-sheath entries, and butt splices on energized (live) and dark fiber optic cables with minimal service disruption, following established Methods of Procedure (MOPs).
Respond to network outages and emergency service calls, efficiently troubleshooting and repairing fiber optic cable damage to minimize downtime and meet Service Level Agreements (SLAs).
Install, terminate, and test various fiber optic connectors (LC, SC, ST) and ensure all connections meet or exceed industry standards for insertion loss and reflectance.
Operate and maintain specialized equipment such as bucket trucks, aerial lifts, and cable lashers in a safe and proficient manner, adhering to all traffic control and public safety guidelines.
Prepare fiber optic cables for splicing, including stripping cable sheathing, cleaning buffer tubes, and identifying fibers using the industry-standard color code.
Meticulously document all work performed, including updating splice records, as-built drawings, and network inventory systems with accurate fiber counts and routing information.
Conduct thorough site surveys to assess construction and installation requirements, identifying potential obstacles and ensuring project feasibility.
Maintain a professional and courteous demeanor when interacting with customers, property owners, and other utility personnel during fieldwork.
Adhere rigorously to all company and industry safety standards, including Confined Space Entry procedures, personal protective equipment (PPE) usage, and safe driving practices.
Perform continuity testing and use a Visual Fault Locator (VFL) to verify fiber paths and identify breaks or bends in close-range applications.

Secondary Functions

Assist in training and mentoring junior technicians or apprentices on advanced splicing techniques, equipment operation, and safety protocols.
Participate in the proactive management of tools, splicing equipment, and vehicle inventory, ensuring all assets are properly maintained, calibrated, and accounted for.
Collaborate with OSP engineers and project managers to provide critical field-level feedback on network designs, construction plans, and material selection.
Conduct routine vehicle and heavy equipment safety inspections to ensure operational readiness, cleanliness, and compliance with company and regulatory standards.
Support network audit and verification projects by physically tracing fiber paths and confirming the accuracy of existing network documentation.
Participate in on-call rotations for after-hours and weekend emergency restoration work as required by business needs.
Install and ground appropriate bonding and grounding hardware for splice closures and cabinets to protect against electrical and lightning damage.
Proactively identify and report potential network integrity risks or areas for improvement in the outside plant infrastructure.
