Fiber Challenges#

  • Signal Loss/Degradation
  • Damaged cables or open connections
  • Dirty connector
  • Attenuation
  • Bend radius limiatation
    • If you bend a cable too much it causes light leakage.

Physical or Signal Mismatch#

  • Connector or transceiver incompatibility
  • Cable incompatibility

Fiber Tools#

  • OTDR: Optical Time Domain Reflectometer
    • Tells you how far down the wire the cable is broken

3 big issues#

  • Attenuation
  • Light Leakage
  • Modal distortion
