Question 11

Twinaxial

Answer 11

Type of Coaxial cable that contains two central copper conductors wrapped around a central shield. Used as substitute for short fiber connections, short distances ex. rack between switches.

Much Cheaper then Fiber
Used this way its called a Direct Attached Cable (DAC)

Question 12

Define Direct Attached Cable (DAC)

Answer 12

Short fiber connection used between equipment on a rack.

Question 13

Twisted Pair

Answer 13

Most common type of cable used in network. Consists of twisted pairs of cables bundled together in a common jacket.

Each pair works as team either transmitting or receiving data.

Helps to reduce crosstalk

Question 14

Define STP

Answer 14

Shielded Twisted Pair

Question 15

UTP

Answer 15

Unshielded Twisted Pair

Question 16

CAT

Answer 16

Category Ratings, officially rated in Mgz. Indicates highest frequency cable can handle

Question 17

Cat 5

Answer 17

Max Freq Max Band Status
100 Mhz 100 Mbps No longer

Question 18

Cat 5e

Answer 18

Max Freq Max Band Status
100 Mhz 1 Gbps Yes

NEEDSCONTEXT

Question 19

Cat 6

Answer 19

Max Freq Max Band Status
250 Mhz 10 Gbps Yes

Can use full 100 Meter length when used with 10/100/1000 BaseT networks

10GBaseT Networks Limited to 55 Meters

Most new cable installations use Cat 6

Question 20

Cat 6a

Answer 20

Max Freq Max Band Status
500 Mhz 10 Gbps Yes

Can use full 100 Meter length with networks up to 10GBaseT
Not limited by network speed over its length

Question 21

Cat 7

Answer 21

Max Freq Max Band Status
600 Mhz 10+ Gbps No

Question 22

Fiber

Answer 22

Transmits light rather then electricity. Makes it attractive for high EMI areas and/or long distance transmission.

Made up of 4 compontents
Glass Fiber - Core
Cladding - Makes light reflect down fiber
Buffer Material - Gives Strength
Insulating Jacket - Insulates and Protects Cable

Answer 25

Subscriber Connector or Standard Connector or Siemon Connector

Stick and Click

Question 26

LC Connector

Answer 26

Local Connector or Lucent Connector

Little Connector

Question 27

MT-RJ Connector

Answer 27

Mechanical Transfer Registered Jack or Media Termination - recommended jack
Latch, gendered
Duplex Node Connections

Question 28

Plenum

Answer 28

Empty space between ceiling tile and concrete ceiling above it

Cables rated for Plenum means it wont create noxious fumes

If it goes in the wall, make it Plenum

Question 29

Fire Rating

Answer 29

Ratings developed to define risk of network burning and creating noxious fumes and smoke

Question 30

IEEE
