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

26
Q

What are the 2 standard pinouts?

A

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

27
Q

What is the Medium Dependent Interface Crossover (MDIX)?

A

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

28
Q

What is a Plenum Cable?

A

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

29
Q

What is a Non-Plenum Cable (PVC)?

A

A normal UTP/STP rated cable

Cannot be used in raised floors, ceilings, or walls

30
Q

What are Fiber Optic Cables?

A

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

31
Q

What are 2 types of Fiber Optic Cables?

A

Single-Mode Fiber & Multimode Fiber

32
Q

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

A

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

33
Q

What are Multimode Fiber (MMF) used for?

A

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

34
Q

What is Wavelength Division Multiplexing (WDM)?

A

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

35
Q

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

A

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

36
Q

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

A

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

37
Q

What are some advantages of Fiber Optic Cables?

A

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

38
Q

What are some advantages for Copper cables?

A

Less expensive, easy to install, inexpensive tools

39
Q

What is a media converter?

A

Converts media from one format to another

Considered a Layer 1 device. Physical conversion of signal only

40
Q

What are Transceivers? What are the 2 types?

A

A

66, 110, Krone, BIX

51
Q

What is a 66 Block used for?

A

Used for phones and older LAN wiring

Bad choice for higher-speed LAN wiring

52
Q

What is a 110 Block used for?

A

USed for higher-speed network wiring

Requires CAT 5 or above cabling

53
Q

What is a Krone Block?

A

A proprietary European alternative to a 110 Block

54
Q

What is a BIX Block?

A

A proprietary punch down block that comes in various sizes

Will need a BIX-specific punch down tool

55
Q

What is a Copper Patch Panel?

A

A device with jacks to connect wiring from the jack to a network switch in a flexible manner.

Has punch downs on the back side, and the front has RJ-45 jacks

56
