What is the preferred standard for a Straight-Through Patch Cable?

T-568B

What are **Crossover Cables**?

Swaps the send and receive pins on the other end of the cable when the connector and its pinout are created

What are the **2 standard pinouts**?

TIA/EIA-568A & TIA/EIA-568B

What is the **Medium Dependent Interface Crossover (MDIX)**?

An automated way to electronically simulate a crossover cable connector even if using a straight-through patch cable | If a switch doesn't support MDIX, use a crossover cable

What is a **Plenum Cable**?

A special coating put on a UTP or an STP cable that provides a fire-retardant chemical layer to the outer insulating jacket | Safe for ceilings, walls, and raised floors

What is a **Non-Plenum Cable (PVC)**?

A normal UTP/STP rated cable | Cannot be used in raised floors, ceilings, or walls

What are **Fiber Optic Cables**?

Uses light from an LED or laser to transmit information through a glass fiber

What are **2** types of **Fiber Optic Cables**?

Single-Mode Fiber & Multimode Fiber

What are **Single-Mode Fiber (SMF)** used for?

Used for longer distances and has a smaller core size which allows for only a single mode of travel for the light signal | Core size is 8.3 - 10 μ in diameter

What are **Multimode Fiber (MMF)** used for?

Used for shorter distances and has a larger core size which allows for multiple modes of travel for the light signal | Core size is 50 - 100 μ in diameter

What is **Wavelength Division Multiplexing (WDM)**?

Combines multiple signals into one signal and sends over a single fiber strand using different wavelengths of the laser light source

How many **wavelength channels, distance, and speed** can a **Coarse WDM (CWDM)** support?

Up to 18 channels, 20 nm, Up to 10 Gbps (Ethernet) & Up to 16 Gbps (Fiber)

How many **wavelength channels, distance, and speed** can a **Dense WDM (DWDM)** support?

Up to 80 channels, 0.8 nm, Up to 8 Tbps (100 Gbps/channel)

What are some **advantages** of **Fiber Optic Cables**?

Higher bandwidth, longer distances, immune to EMI, better security

What are some **advantages** for **Copper** cables?

Less expensive, easy to install, inexpensive tools

What is a **media converter**?

Converts media from one format to another | Considered a Layer 1 device. Physical conversion of signal only

What are **Transceivers**? What are the **2** types?

Device that sends and receives data. Bidirectional & Duplex

What is a **Bidirectional Transceiver**?

Devices take turns communicating | Known as half-duplex

What is a **Duplex Transceiver**?

When devices can both communicate at the same time | Also known as full duplex

What are the **5** types of **transceivers** used in switches and routers?

GBIC, SFP, SFP+, QSFP, QSFP+

What is a **Gigabit Interface Converter (GBIC)**?

A standard, hot-pluggable gigabit Ethernet transceiver (copper or fiber)

What is a **Small Form-Factor Pluggable (SFP)** and what does it support up to?
