Ethernet Cabling/Connectors

Question 1

Cat 3

Answer 1

Networks: older 10Base-T

Data Rate: 10-16mbps

Question 2

Cat 5

Answer 2

Networks: 10Base-TX

Data Rate: 100mbps (ATM @155mbps)

Question 3

Cat 5e

Answer 3

Networks: 1000Base-T
Data Rate: 1Gbps
reduced crosstalk compared to cat 5

Question 4

Cat 6

Answer 4

Network 1000Base-T
Data Rate: 1Gbps
reduced crosstalk compared to cat 5

Question 5

Cat 6e

Answer 5

Network: 10G Base-T
Data Rate: 10Gbps
augmented, supports twice as many frequencies as cat 6

Question 6

MMF: Multimode Fiber

Answer 6

• shorter distance limitations

* multimode delay distortion:

Question 7

SMF: Single Mode Fiber

Answer 7

• only one mode of propagation, core diameter is smaller to only permit one mode of propagation
• longer distance limitations
• higher cost

Question 8

RJ45 Connector

Answer 8

• twisted pair connector

* 8pin connector

Question 9

RJ11 Connector

Answer 9

Twister Pair Connector

• up to 6 pin connector, most have only 2 or 4
• found in most home telephone networks

Question 10

DB9 (RS232) Connector

Answer 10

Twisted Pair Connector

• 9 pin
• older connector used for low speed asynchronus serial communications - PC to a serial printer, PC to a console port of a router/switch, PC to external modem

Question 11

Straight Tip (ST)

Answer 11

Fiber Optic Connector

• “bayonette connector”
• used in MMF
• Connects a terminating device by pushing the connector into the terminating equipment and then twisting the connector housing to lock into place

Question 12

Subscriber Connector (SC)

Answer 12

Fiber Optic Connector

• “standard/square” connector
• Connected by pushing the connector into the terminating device, can be removed by pulling the connector from the terminating device

Question 13

Lucent Connector (LC)

Answer 13

Fiber Optic Connector
* Connects to a terminating device by pushing the connector into the terminating device, can be removed by pressing the tab on the outer connector and pulling it out

Question 14

Mechanical Transfer Registered Jack (MTRJ)

Answer 14

Fiber Optic Connector

• two fiber stands included in a single connector (transmit and receive)
• Connected by pushing the connector into the terminating device, can be removed by pulling the connector from the terminating device
