If you walk into multiple data centers, you’ll probably start to see some similarities. In this video, you’ll learn about some of the most common network devices on today’s networks. << Previous Video: Ethernet Standards Next: Advanced Networking Devices >> If you’re an early user of Ethernet over twisted pair cabling, then you are probably […]

The IEEE maintains Ethernet standards that apply to many different speeds and media. In this video, you’ll learn about 100BASE-TX, 1000BASE-T, 1000BASE-SX, 1000BASE-LX, and 10GBASE-T standards. << Previous Video: Network Transceivers Next: Networking Devices >> By far, Ethernet is the most popular network topology in the world. Somebody has a network, and they have some

Transceivers can provide options when connecting infrastructure equipment to the network. In this video, you’ll learn about transceiver technology, duplex and bi-directional transceivers, GBICs, SFP/SFP+, and QSFP transceivers. << Previous Video: Network Termination Points Next: Ethernet Standards >> A transceiver is a device that is both a transmitter and a receiver, and usually it’s in

Most network designs follow similar methods to connect the end stations to the network. In this video, you’ll learn about patch panels, punch-down blocks, patch panels, and fiber distribution panels. << Previous Video: Copper Termination Standards Next: Network Transceivers >> In most modern work environments, we have a lot of people that are sitting at

Once you’ve picked your copper cabling, you’ll need to terminate it properly. In this video, you’ll learn about the different standards associated with copper cabling. << Previous Video: Optical Fiber Connectors Next: Network Termination Points >> The type of copper cables you use on your network is important. But also the termination of those cables

The connector types between fiber-connected devices can vary. In this video, you’ll learn about ST, SC, LC, and MT-RJ fiber connectors. << Previous Video: Optical Fiber Next: Copper Termination Standards >> There are many different kinds of fiber connectors. So in this video, I’ll take you through some of the more common types that you’d

Optical fiber operates with very different physics than copper cabling. In this video, you’ll learn about multimode fiber, single-mode fiber, and the difference between UPC and APC connections. << Previous Video: Copper Connectors Next: Optical Fiber Connectors >> Communication over optic fiber is communicating using wavelengths of light. This is very different than communicating using

There are many different ways to connect copper cable to your networking equipment. In this video, you’ll learn about RJ11, RJ45, BNC, DB-9/DB-25, and F connectors. << Previous Video: Copper Cabling Next: Optical Fiber >> If you’re connecting up a traditional phone line or you’re using a modem connection over a traditional phone line, then

Copper cables are the foundation of our networks, but not every copper cable is the same. In this video, you’ll learn about unshielded and shielded twisted pair, network cabling standards, and different types of network cabling. << Previous Video: An Overview of NTP Next: Copper Connectors >> For most of us, the foundation of our
