DB-25 connector, F-connector BNC connector

Question 16

Fiber communication

Answer 16

• Transmission by light • The visible spectrum
• No RF signal - • Very difficult to monitor or tap
• Transmission over long distances
• Immune to radio interference - There’s no RF

Question 17

UPC (Ultra-polished connectors)

Answer 17

• Ferrule end-face radius polished at a zero degree angle
• High return loss
MultimodeFiber
Shortrangecommunication,up to2km

Question 18

APC (Angle-polished connectors)

Answer 18

• Ferrule end-face radius polished at an eight degree angle

* Lower return loss, generally higher insertion loss than UPC

Question 19

Optical Fiber Connectors

Answer 19

ST - Straight Tip SC - Subscriber Connector

LC - Lucent Connector MT-RJ - Mechanical Transfer Registered Jack

Answer 21

• Wire-to-wire patch panel
• No intermediate interface required
• Replaces the 66 block
• Patch Category 5 and Category 6 cables
• Additional wires punched into connecting block

Question 22

Copper patch panel

Answer 22

• Punch-down block on one side, RJ45 connector on the other
• Move a connection around - Different switch interfaces
• The run to the desk doesn’t move

Question 23

Fiber distribution panel

Answer 23

• Permanent fiber installation - Patch panel at both ends

* Fiber bend radius - Breaks when bent too tightly
