Network Media (UTP Cabling (Testing (Wire map, Cable length, Signal loss…

- - - - misalingment when fiber joined
      - end gap between fibers
      - end finish (no en conection)
      - otdr for testing
  - - - SMF - uses laser, for long cabling distances
      - MMF - uses led emmisions at different angles
      - ST,SC,LC
  - - - for device interconnection
      - Enterprise networks
      - Others: FTTH, Long-haul Networks, Submarine Networks
  - - - more bandwith than any other media
      - less attenuation
      - Immune to EMI and RFI
      - light impulses as data
        
        laser, leds
- - - - problems
        
        coverage area
        
        interference
        
        security
        
        shared medium (less bandwith)
  - - - antenna
      - signal reception and decoding
      - frequency and power of transmission
      - data to radio signal encoding
