Chapter 5: Modern Ethernet Pg107-114

Must be able to:
         - Categorize standard media types and associated propertiees: media converters, distance limitations
         - Categorize standard connector types based on network media: fiber
         - compare and contrast different LAN technologies
         - Describe the varieties of 100-megabit ethernet
         - discuss coper and fiber based gigabit ethernet
         - compare the competing varieties of 10 gigabit ethernet

Upgrading from 10BaseT to 100 BaseT
         - First: Use CAT5 cable or better
         - Must replace all old 10BaseT NICs with 100BaseT NICs
       
 100BaseFX
         - 100 Megabit Ethernet fiber-optic cable
         - also known as 100BaseF
         - Speed: 100 Mbps
           Signal Type: Baseband
           Distance: 2Km between the hub and node
           Node Limit: 1024 per node
           Topology: Star-bus topology, physical star, logical bus
           Cable Type: multimode fiber-optic cabling with ST or SC connectors

Full-Duplex Ethernet
          - Can send and receive data at the same time
          - doesn't increase network speed, but doubles bandwidth
        

Gigabit Ethernet
          - 1000BaseT
          - 1000BaseX

1000BaseCX
         - uses twinaxial cable (or twinax)
         - 150-Ohm cables with length limit of 25 meters

1000BaseSX
         - multimode fiber-optic cables
         - max cable length of 220-500 meters
         - uses 850 nm wavelength LED
       
1000BaseLX
        - single-mode (laser) cables
        - max length of 5-70 Km
