20
Q

What is a crossover cable?

A

T568A to T568B

21
Q

What is Medium Dependent Interface Crossover? (MDIX)

A

An automated way to electronically simulate a crossover cable connector even if using a straight-through patch cable

22
Q

What is the wiring standard for 568B?

A

Same as 568A except you switch out pins one, two, three and six (orange and green pairs swapping places)

23
Q

Plenum

A

fire retardant chemical layer to the outer insulating jacket; used anytime you’re putting cable in a place you can’t see like ceilings or walls

24
Q

What is a Single Mode Fiber (SMF) Fiber Optic Cable?

A

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

25
Q

What is Multimode Fiber (MMF)?

A

Used for shorter distances and has larger core size which allows for multiple modes of travel for the light signal; any place you would typically use a straight through patch cable is where you might use a MMF; remember three things: larger core size, covers shorter distances, less expensive (it’s the exact opposite for SMF) (yellow sheath is usually SMF)

26
Q

What is SC (Subscriber Connecter) in fiber optic cabling?

A

low cost, durable, easy to install; stick and click; looks like an optical cable

27
Q

ST (Straight Tip) connector for fiber

A

Stick and Twist; no click, but twist and lock

28
Q

LC connector

A

lucent connector; love connector; it has two identical things side to side; always married together

29
Q

MTRJ

A

mechanical transfer registered jack (half the size of the others); two prongs

30
Q

Two different types of connectors for fiber

A

Angled Physical Contact (APC) Connector - angled at 8 degrees and light is reflected into the clouding of the cable (connector is green)
Ultra Physical Contact (UPC) Connector - no angling, more curvature; better alignment; more noise and some signal loss (connector is blue)

31
Q

What is Wavelength Division Multiplexing (WDM)?

A

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

32
Q

Coarse WDM (CWDM)

A

up to 18 channels
20 nm channel distance
speed up to 10 Gbps (Ethernet) and 16 Gbps (Fiber)

33
Q

Dense WDM (DWDM)

A

up to 80 channels
0.8nm channel distance
up to 8 Tbps (100 Gbps/channel)

34
Q

Media Converter

A

Converts fiber optic to copper or the opposite; can also be done with coax

35
Q

Bidirectional

A

known as half duplex; like using a walkie talkie

36
Q

duplex

A

aka full duplex; allows both devices to communicate at the same time. Like a telephone conversation

37
Q

small form-factor pluggable (SFP) transceiver

A

up to 4.2 Gbpbs

38
Q

SFP+

A

up to 16 gbps

39
Q

quad small form factor pluggable (QSFP)

A

up to 40 gbps

40
Q

QSFP+

A

up to 41.2 gbps

41
Q

QSFP28

A

up to 100 gbps

42
Q

QSFP56

A

up to 200 gbps

43
Q

demarcation point

A

where you isp’s service connection ends and yours begins

44
Q

backbone switch

A

everything in your network connects to it

45
Q

edge switch

A

this is a switch that connects to your backbone switch (use trunk lines)

46
Q

Main Distribution Frame (MDF)

A

a telco closet which serves as the main starting point for all starting cabling

47
Q

IDF (Intermediate Distribution Frame)

A

smaller than MDF; contains an edge switch, patch panel and other associate equipment to support the floor and offices nearest to it

48
Q

Patch Panel

A

keeps your cabling organized

49
Q

toner probe

A

use it to find the correct cable that’s plugged into the wall jack and patch panel; find breaks int he wire
