Connections

Question 1

IEEE

Answer 1

Institue of Electrical and Electronics Engineers
- standard for wireless networking (802.11 committee)

Question 2

LTE

Answer 2

Long term evolution
- a 4G technology
EDGE - enhanced data rates for GSE evolution

Question 3

5G

Answer 3

10gb/sec

Question 4

Satellite Networking

Answer 4

High cost/complexity
- not as fast as cables
- Relatively high latency
- needs a direct line of sight (thunderstorm)

Question 5

Ethernet

Answer 5

Most popular networking standard of the world

Question 6

IEEE 802.3 Committee

Answer 6

Governs all types and standards of ethernet from copper to fiber

Question 7

Deciphering the Standard
Ex. 1000Base-T

Answer 7

Number means speed
Base = baseband (single frequency)
-T means fiber
-SX means short wavelength light

Question 8

Fiber

Answer 8

Send via light (visible spectrum)
- More secure
- Used over long distances
- Immune to radio interference

Question 9

Fiber Optic Cable

Answer 9

LED entry that takes in the light ray and outputs it to a reciever
- Buffer coating (the rubber on the outside)
Cladding (In inner tube)
Corer - high reflective index

Question 10

Multimode Fiber

Answer 10

Short range communication
- inexpensive light source

Question 11

Single-mode Fiber

Answer 11

Long range communication (up to 100km)
- laser beams
- expensive light source

Question 12

Twisted Pair Copper Cabling

Answer 12

Balanced pair opertion
- Two wires with equal and opposite signals
- Transmit+, transmit-/recieve + recieve-

Question 13

Why do we need a twist cabling?

Answer 13

To prevent interference as signals are compared on the other end
- different twist rates

Question 14

What cable category do you need for 1000 Base - T minimum?

Answer 14

Category 5

Question 15

Coaxial Cables

Answer 15

Used mainly for RG-6 in television/digital cable

Question 16

Twinaxial Cable

Answer 16

10g ethernet, two iner conductors

Question 17

Plenum Space

Answer 17

Drop ceilng and actual ceiling for cables

Question 18

Plenum-rated cable

Answer 18

Tranditional cable jacket
- Polyvinyl Chloride
Fire rated cable jacket
- Fluorinated etherlene polymer FEP
Low-smoke polyvinyl chloride PVC

• safer for fire but maybe not as flexible

Question 19

Transceiver

Answer 19

Both for trasmitting and recieving
- Can offer a wide range of different cables to be used with it

Question 20

SFP and SFP+

Answer 20

Type of transciever
Small form factor pluggable
- Offers fiber and copper support 1g+

Enhanced SFP+
- Provides higher speed 10g+
