Network Fundamentals Module 4

Multimode Fiber

- Larger core - Uses less expensive LED's -LED's transmit at different angles - Up to 10 Gbps over 550 meters - Orange jacket

Single-Mode Fiber

- Very small score - Uses expensive lasers - Long-distance applications - Yellow jacket

Ethernet Straight-through

Both ends T568A or both ends T568B. Connects a network host to a network device such as a switch or hub.

Which of the following attaches antennas to wireless devices? It can also be bundled with fiber-optic cabling for two-way data transmission.

Coaxial

Which of the following terminates with BNC, N type and F type connectors?

Coaxial

Ethernet Crossover

One end T568A other end T568B Connects two network hosts Connects two network intermediary devices (switch to switch, or router to router)

Which of the following counters EMI and RFI by using shielding techniques and special connectors?

Shielded Twisted-Pair (STP)

Which of the following is the most common network media?

Unshielded Twisted-Pair (UTP)

Long-Haul Networks

Used by service providers to connect countries and cities.

Enterprise Networks

Used for backbone cabling applications and interconnecting infrastructure devices.

Fiber-to-the-Home (FTTH)

Used to provide always-on broadband services to homes and small businesses.

Submarine Cable Networks

Used to provide reliable high-speed, high-capacity solutions capable of surviving in harsh undersea environments up to transoceanic distances.
