  6. How is Ethernet Is Denoted

    Slide 6 - How is Ethernet Is Denoted

    • Ethernet cable types
    • N<Signaling>–X
    • N refers to the signaling rate in megabits per second
    • <Signaling> stands for the signaling type—either baseband or broadband
    • X is a unique identifier for a specific Ethernet cabling scheme
    • Examples:
    • 100Base-TX (means 100 megabits per second over baseband – using twisted pair cable)
    • 1000Base-F (means 100 Megabits per second over baseband – using Fiber)
    • N (signal Rate)…………..Signaling………………………Type of Media100…………………………...BASE…………………………….TX
    • (Baseband = information is carried in digital form on a single unmultiplexed signal channel on the transmission medium)
    • http://searchnetworking.techtarget.com/definition/baseband
  7. First, we will talk about Copper Cables - Twisted Pair Cables

    Slide 7 - First, we will talk about Copper Cables - Twisted Pair Cables

    • Twisted-pair cables consist of multiple individually insulated wires twisted together in pairs
    • Twisting minimizes signal interference, or crosstalk
    • There are 2 types of “twisted” pair cables
    • Shielded twisted pair (STP) has metallic foil-like shield placed around wires
    • Unshielded twisted pair (UTP) is twisted-pair cable without outer shielding
    • UTP (Unshielded Twisted Pair) is the most commonly used form and is less expensive.
    • http://www.infocellar.com/networks/cables/twisted-pair-cables.htm
  8. Unshielded Twisted Pair

    Slide 8 - Unshielded Twisted Pair

    • Why unshielded twisted-pair wire is preferred in modern Ethernet network configurations:
    • It is cheaper than other types of cabling
    • Cheaper than shielded twisted pair
    • Cheaper than fiber optic
    • It is easy to work with.
    • It allows transmission rates that were impossible 10 years ago
    • It’s good for short distances (like from the local telecom closet switch to your work computer on your desk)

  9. How Do you Terminate and Connect Unshielded Twisted Pair?  - RJ Connectors

    Slide 9 - How Do you Terminate and Connect Unshielded Twisted Pair? - RJ Connectors

    • UTP uses registered jack (RJ) connectors
    • RJ-11 connects a phone to a phone jack
    • Used with UTP cable similar to Category 1 cable and uses two pairs (four wires)
    • RJ-22 used for handsets of older style telephones
    • RJ-45 is used in Ethernet data networks
    • Uses four pairs of wires (eight wires)
    • Usually associated with Category 3 or higher UTP wire
    • wkhchemconsult.blogspot.com
  10. There are “categories” of UTP  (Category Cabling)

    Slide 10 - There are “categories” of UTP (Category Cabling)

    • The number of twists and the direction the twists turn in a given meter of wire varies according to how much and what types of interference the twisted-pair wires are trying to minimize
    • Twisted-pair wire is rated using these “categories”
    • CAT followed by a number
    • Common grades of twisted-pair wires used in LANs are CAT 5, CAT 5e, and CAT 6
  11. So How are these Categories “Different”?

    Slide 11 - So How are these Categories “Different”?

    • More twists in a Cat6e to handle interference
    • Than there are for a Cat 5
    • http://customcable.ca/cat5-vs-cat6/
    • The number of twists are greater in the more modern (Cat5e and Cat6 standards)
    • This helps alleviate interference
