Core Responsibilities

Primary Functions

  • Perform fusion and/or mechanical splicing of single and mass fiber optic cables in both outdoor and indoor settings, ensuring minimal signal loss and maximum integrity.
  • Construct and prepare various types of splice closures (e.g., dome, inline) and cabinets, meticulously arranging and securing buffer tubes and fibers.
  • Read, interpret, and accurately follow complex engineering blueprints, splice diagrams, and work orders to execute installation and repair tasks.
  • Operate specialized testing equipment, including Optical Time Domain Reflectometers (OTDR), power meters, and visual fault locators (VFLs), to verify signal strength, identify faults, and certify cable performance.
  • Perform intricate copper cable splicing, including bonding, grounding, and encapsulating splices to protect them from environmental factors.
  • Install, terminate, and test cables on distribution frames, patch panels, and other telecommunications equipment within central offices, data centers, or customer premises.
  • Troubleshoot and diagnose issues in fiber optic and copper networks, systematically identifying the root cause of service disruptions and performing necessary repairs.
  • Work safely in a variety of challenging physical environments, which may include confined spaces like manholes, heights on aerial lifts or ladders, and adverse weather conditions.
  • Skillfully prepare and handle a wide range of cable types (e.g., loose tube, ribbon, armored) without causing damage to the delicate internal fibers or conductors.
  • Document all splicing, testing, and repair activities with meticulous detail, updating as-built drawings, splice records, and test result databases.
  • Perform mid-sheath entries on live fiber optic cables to add or remove fibers without interrupting existing services, a process requiring extreme precision and care.
  • Ensure all work adheres to or exceeds company standards, industry specifications (such as TIA/EIA), and local, state, and federal regulations (e.g., NEC, OSHA).
  • Operate and maintain heavy equipment, such as bucket trucks, aerial lifts, and cable trailers, in a safe and proficient manner.
  • Conduct thorough site surveys to assess installation requirements, identify potential obstacles, and contribute to the planning of cable routes and splice locations.
  • Execute emergency restoration procedures for cut or damaged cables, working under pressure to restore critical communication services as quickly as possible.
  • Perform sheath repair on damaged aerial, buried, or underground cables to prevent moisture intrusion and extend the life of the infrastructure.
  • Install and maintain appropriate grounding and bonding for all cables and hardware to protect the network and personnel from electrical hazards.
  • Manage and maintain an inventory of tools, equipment, and materials on a company-provided vehicle, ensuring everything is in proper working order.
  • Interface professionally with project managers, engineers, and other field personnel to coordinate work activities and ensure project timelines are met.
  • Place and install innerducts and conduits as needed to create clear and protected pathways for new cable installations.

Secondary Functions

  • Maintain vehicle, tools, and equipment in excellent condition, performing regular checks and reporting any operational issues or needs for repair.
  • Provide clear and concise updates to project managers and supervisors on job progress, unforeseen challenges, and task completion.
  • Assist in the on-the-job training and mentoring of apprentice technicians, sharing knowledge of best practices, safety protocols, and advanced techniques.
  • Participate actively in daily safety briefings ("tailgate talks") and contribute to a culture of safety-first on all job sites by identifying and mitigating hazards.
