    IEEE Standard for Ethernet IEEE Computer Society Sponsored by the LAN/MAN Standards Committee IEEE 3 Park Avenue IEEE Std 802.3™-2012 New York, NY 10016-5997 (Revision of USA IEEE Std 802.3-2008) 28 December 2012 IEEE Std 802.3™-2012 (Revision of IEEE Std 802.3-2008) IEEE Standard for Ethernet Sponsor LAN/MAN Standards Committee of the IEEE Computer Society Approved 30 August 2012 IEEE-SA Standard Board Abstract: Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 100 Gb/s using a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted-pair or fiber optic cables. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted-pair PHY types.

  • Hybridní Ethernet (1)
    Hybridní Ethernet (1) • Jedná se o kombinaci dříve uvedených typů sítě Ethernet • Tuto kombinaci lze provést pomocí: – hybridního adaptéru (BNC/řada N): mezi tenkým a silným koaxiálním kabelem – repeateru: mezi tenkým a silným koaxiálním kabelem – hubu: mezi tenkým, silným koaxiálním kabelem a kroucenou dvojlinkou 2018-06-01 1 Hybridní Ethernet (2) RJ-45 BNC + T + BNC konektor # # # max. 100 (400) m Terminátor # # AUI konektor # # Hub N + T + N konektor nebo jehlový konektor Repeater min. 0,5 m max. 185 (300) m (300) 185 max. # # # m 500 max. Drop kabel Transceiver (MAU) (max 50 m) # # # # # min. 2,5 m 2018-06-01 2 10Broad36 (1) • Jako přenosové médium používá koaxiální kabel s char. impedancí Z0 = 75 W pracující v přeloženém pásmu • Činnost v přeloženém pásmu umožňuje, aby koaxiální kabel byl využíván i pro přenos jiných informací (např. video), než jsou data přenášená v síti • Jednotlivé stanice se ke koaxiálnímu kabelu připojují pomocí transceiveru a pomocného (drop) kabelu (max. 50 m) 2018-06-01 3 10Broad36 (2) • Maximální délka jednoho kabelu je 1800 m • Všechny sítě 10Broad36 jsou zakončeny pomocí tzv. head-end zařízení, které může být na konci jednoho kabelového segmentu nebo jako kořen více kabelových segmentů • Na druhém konci je síť ukončena termináto- rem • Tímto je možné zvětšit fyzický rozsah célé sítě až 3600 m (s drop kabely 3700 m) 2018-06-01 4 10Broad36 (3) • Síť 10Broad36 může být vybudována ve dvou konfiguracích: – s jedním koaxiálním kabelem: • datové přenosy jsou rozděleny do dvou kanálů, z nichž každý využívá jiné
