Core Skills

  • Fiber optic multiplex system fault isolation
  • Preventive and corrective maintenance of FODMS equipment

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Telecommunications Line Installers and Repairers

FODMS troubleshooting and fault isolation provide a foundation for locating faults in civilian fiber optic telecommunications infrastructure.

How to prepare: Complete hands-on cable testing and splicing training to extend equipment-level maintenance experience to telecommunications lines.

What the civilian work involves
  • Set up service for customers, installing, connecting, testing, or adjusting equipment.
  • Inspect or test lines or cables, recording and analyzing test results, to assess transmission characteristics and locate faults or malfunctions.
  • Splice cables, using hand tools, epoxy, or mechanical equipment.

Photonics Technicians

Preventive and corrective maintenance of FODMS and its support equipment transfers to the optical-equipment maintenance side of photonics technician work.

How to prepare: Take a laboratory course in optical equipment testing and calibration, with practice recording test data and documenting procedures.

What the civilian work involves
  • Compute or record photonic test data.
  • Adjust or maintain equipment, such as lasers, laser systems, microscopes, oscilloscopes, pulse generators, power meters, beam analyzers, or energy measurement devices.
  • Document procedures, such as calibration of optical or fiber optic equipment.
