Deploying Ethernet Cabling

Question 1

Work Area

Answer 1

• Space where user connects equpment to network, usually via wall port

Question 2

Horizontal Cabling

Answer 2

• Connects user work areas to nearest horizontal cross-connect
• Cross connect sometmes call distrubution frame

Question 3

Backbone Cabling

Answer 3

• Connects HCCs (Horizontal Cross Connects) to main coss connect
• Also know as vertical cross connects

Question 4

Telecommunications Room

Answer 4

• Houses Horizontal cross-connects
• Termination point for horizontal cabling
• Likely to house equipment like Switchers, routers, modems

Question 5

Entrance Facilities/Demar

Answer 5

• Special equpment rooms where external cabling is joined to internal

Question 6

IDC

Answer 6

Insulation Displacement Connection

• Contains contacts that cut insulation from a wire and hold it in place
• Allows large number of cables to be terminated in one place

Question 7

66 Block

Answer 7

• Older style distribution frame
• 50 rows of 4 IDC terminals
• Jumper is installed to complete connection

Question 8

110 Block

Answer 8

• Developed by AT&T
• Supports Cat 5 and better
• Arranged horizontally instead of vertically, offered better density than 66
• More space for labeling and color coding
• Incoming wire is fed into channel on wiring block, then connector block is installed to terminate incoming wiring

Question 9

BIX and Krone Distrubtion Frames

Answer 9

• Uses a single module
• Krone more common in Europe
• Use different termination blade

Question 10

Patch Panel

Answer 10

• Distribution block with IDC’s on one side and preterminated RJ-45 modular ports on the other
• Allows incoming and outgoing connections to be reconfigured without reterminating punchdown blocks

Question 11

SFP/SFP+

Answer 11

Small Form Factor Pluggable

• New form factor of transceiver module which replaced GBIC
• Also know as mini-GBIC
• Uses LC connections and is designed for Gigabit Ethernet
• SFP+ updated for 10 GbE, but still uses LC
• Different modules support various ethernet standards

Question 12

QSFP/QSFP+

Answer 12

Quad small form-factor Pluggable

• transceiver form factor that supports 4 x 1 Gps links, aggregated to a single 4 Gbps channel.
• QSFP+ is designed to support 40 GbE

Question 13

WDM

Answer 13

Wavelength Division Multiplexing

• Means to use a single strand to transmit and/or receive more than one channel at a time
• Coarse: Supports up to 16 wavelengths, used to deploy 4-8 bidirectional channels
• Dense: Supports greater numbers, uses precise and expensive lasers

Question 14

BiDi

Answer 14

Bidirectional tranceivers

• support transmit and receive signals over the same strand of fiber
• Uses WDM to transmit Tx and Rx signals over slightly shifted wavelengths
• Must be installed in opposite pairs

Question 15

Cable Crimper

Answer 15

• Used to create a patch cord
• Fixes plug to cable
• Specific to connector type and cable

Question 16

Fiber Distribution Panel

Answer 16

• Distribution Frame with pre-wired connected used with fiber optic cabling

Question 17

Fusion Splicer

Answer 17

• Joines fiber strands
• achieves a more permanent join with lower insertion loss
• Must be kept cleaned and maintained

Question 18
