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
