Industry & Occupation
Classification
Summary
Specialized profession that installs conduits and ducts underground for communication cables, lays optical fiber and coaxial cables, performs fusion splicing connections, and conducts tests.
Description
Underground communication line wiring workers install conduits and ducts in roads and premises, pull in optical fiber cables and coaxial cables, and perform connection work using fusion splicers and crimp terminals. After the work, they use measuring instruments such as OTDR to test for loss or breaks and create records. Much of the work is outdoors, in underground tunnels, or inside manholes, involving carrying heavy cable drums and awkward postures in confined spaces, requiring physical strength and attention. Before construction, they perform traffic guidance and safety management, proceeding with construction cooperatively in teams according to the work plan.
Future Outlook
Stable job demand is expected due to continued needs for construction and renewal of communication infrastructure such as 5G and FTTH, while the aging of skilled technicians and labor shortages remain challenges.
