Q

Twinaxial

A

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)

Q

Twisted Pair

A

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

Q

CAT

A

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

17
Q

Cat 5

A

Max Freq Max Band Status
100 Mhz 100 Mbps No longer

18
Q

Cat 5e

A

Max Freq Max Band Status
100 Mhz 1 Gbps Yes

NEEDSCONTEXT

19
Q

Cat 6

A

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

20
Q

Cat 6a

A

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

21
Q

Cat 7

A

Max Freq Max Band Status
600 Mhz 10+ Gbps No

22
Q

Fiber

A

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

23
Q

Cat 8

A

Max Freq Max Band Status
2000Mhz 25-40 Gbps No

24
Q

ST Connector

A

Straight Tip or Snap and twist

Bayonet Style

25
Q

SC Connector

A

Subscriber Connector or Standard Connector or Siemon Connector

Stick and Click

26
Q

LC Connector

A

Local Connector or Lucent Connector

Little Connector

27
Q

MT-RJ Connector

A

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

28
Q

Plenum

A

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

29
Q

Fire Rating

A

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

30
Q

IEEE

A

Institute of Electrical and Electronics Engineers

Define frames, speeds, distances, and types of cabling to use in a network environment
