2211 LANs, VLANs, Wireless and Optical Ethernet

In this course, we will understand Ethernet: the fundamentals, equipment and implementations including twisted-pair copper, wireless and fiber. You'll learn about broadcast domains, MAC Addresses and MAC Frames, Layer 2 switches, VLANs, 1000BASE-T, building wiring, 802.11 Wireless LANs, fiber and Optical Ethernet in the core, MANs and PONs.

Course Lessons
1. Introduction
2. Broadcast Domains, MAC Addresses and MAC Frames
3. LAN Switches a.k.a. Layer 2 Switches
4. VLANs
5. 802 Standards: 802.3 Twisted Pair and 802.11 Wi-Fi
6. Twisted-Pair LAN Cables, Wiring Plan and Switch Hierarchy
7. Optical Ethernet and Fiber Links

Taking this course, you'll gain a solid understanding of this essential technology:
• Broadcast domains
• MAC addresses and MAC frames
• What a LAN switch is, and what it does.
• How VLANs can be used to segregate devices into different broadcast domains.
• The 802.3 standard and communicating MAC frames at 10 Mb/s on coaxial cables to Gigabit Ethernet on copper and fiber. What the code 1000BASE-T means.
• MAC frames over the Ether, a.k.a. Wi-Fi, the 2.4 and 5 GHz unlicensed bands, and the fundamentals of how the bits in MAC frames are communicated using radio carrier frequencies.
• Wiring Ethernet to the work area with Cat 5, Cat 5e and Cat 6 twisted-pair copper-wire cables, wiring closets and Layer 2 aggregation switches.
• What Optical Ethernet is, and how it is the building block of telecom networks, including Metropolitan Area Networks (MANs), carrier MPLS networks, and Passive Optical Networks (PONs) for fiber to the home.
• The fundamentals of how the bits in MAC frames are communicated using light guided in glass tubes. How fiber cables are deployed and connected to equipment at each end. What designations like 100GBASE-ER4 mean.

Based on Teracom’s famous Course 101, tuned and refined over the course of more than 25 years of instructor-led training and counting. We’ll cut through the jargon to demystify Ethernet, MAC addresses, LANs and VLANs, explaining the jargon and buzzwords, the underlying ideas, and how it all works together… in plain English.
