Fibre handling, cleaning and inspection in the field
For network, data center and low-voltage technicians who patch, move and troubleshoot fibre connections in comms rooms and racks. It builds on Fiber cleaning and inspection (which introduces scopes, end-face zones and APC/UPC) and goes further into the field routine: handling cable and cords within bend, tension and crush limits; running inspect-clean-inspect on both plugs and ports; deciding what to do when a connector still fails and recording the result; and working safely with invisible light, glass shards and solvents. Safety references are US (OSHA Technical Manual) plus industry guidance; follow your employer's procedures and local rules. The course doesn't grant a licence or certification. Ends with a supervisor-observed practical demonstration.
