Title: wrightfrank447Terminating a Fiber Optic Cable

Terminating a Fiber Optic Cable
  • How to ensure minimal insertion loss and material

  • Fiber optics are becoming an indispensable part
    of any high bandwidth network structure. Owing to
    the small structure and immunity to
    electromagnetic interferences, fiber optic cables
    can be inconspicuously hidden with overhead
    ducts, conduits, or buried underground.
  • However, since the medium of transmission is
    light waves, it is crucial to have the ends
    terminated properly.
  • Improper fiber termination can result in
  • Significant Transmission Loss
  • High Light Loss i.e., high insertion loss
  • Dirt or dust can enter into the exposed ferrule.
  • Complete signal loss due to internal breakage
  • High Optical return loss

How to Terminate a Fiber Optic Cable
Step 1 Gather Materials
  • Fiber optic termination, just copper wire
    termination, requires certain precision tools and
    specialized materials along with the fiber optic
  • Other materials required during termination
  • Safety Glasses
  • Protective gloves
  • Disposal bin
  • Iso-Propyl Alcohol or any other stripping agent
  • Epoxy or Adhesive
  • Some of the tools to keep in handy are
  • Cable jacket stripper
  • Polishing puck or film for face end polishing
  • Shears or Scissors
  • Tester Microscope
  • Fiber cleaver

Step 2 Strip the Cable
  • Measure the cable length you will need. Leave
    additional one inch on either sides before
    cleaving the ends.
  • Score the end using a cleaver tool once and bend
    the cable to break the ends cleanly.
  • Using the jacket stripper to remove the outer
    jacket and expose the inner fiber core.
  • Jacket Stripping Tool
  • Fiber Cleaving Tool

Step 3 Remove any stains or debris
  • Using a shear or scissor remove the aramid yarn
    around the glass core.
  • Most of the times, field terminations may lead to
    dust, dirt, and stains to gather on the exposed
  • Remove them by dipping the cable in
    hydrofluoroethers (HFE) and hydrofluorocarbons
    (HFC) based cleaning solutions

Step 4 Attach the connector and cure the Epoxy
  • Based on the application, place the connector on
    the exposed core. Ensure there is at least a half
    inch glass strand exposed on the other side of
    the connector.
  • Once in place, pour some epoxy on the end of the
    connector. The epoxy acts an adhesive, bonding
    the connector to the ferrule core.
  • Place the cable in an oven with the connector
    facing down. This prevents the epoxy from wicking
    down to the cable.

Step 5 Cleave the end and Polish it
  • The final steps in fiber optic cable termination
    is cleaving the cable end to the right face.
  • There are 4 type of polished ends you can achieve
    in fiber optic cables
  • Flat polish
  • Physical Contact
  • Ultra Physical Contact
  • Angled Physical Contact
  • Use a polishing puck to achieve the right type of
    polished end.
  • All that remains is to test the cable and you are
    one cable down.
