Copper/fiber media

Copper/fiber media

1. electromagnetic interference (EMI)

   • shieding
     • twisted-pair cabling
       • unshielded twisted-pair cable (UTP)
   • copper cable

2. RJ-45 connectors

   • pin positions
     • receive and transmit on different pis

3. Fiber optic cable

   • no EMI effect
   • optical transmitter
     • light pulses
       • Light emitting diode (LED)
         • Shine in many directions
       • laser
         • shine one direction
         • travels farther
   • optical receiver
   • Outer jacket
     • stregnthener
       • buffer
         • cladding
           • core
