Deploying Ethernet Cabling Flashcards
1
Q
Work Area
A
- Space where user connects equpment to network, usually via wall port
2
Q
Horizontal Cabling
A
- Connects user work areas to nearest horizontal cross-connect
- Cross connect sometmes call distrubution frame
3
Q
Backbone Cabling
A
- Connects HCCs (Horizontal Cross Connects) to main coss connect
- Also know as vertical cross connects
4
Q
Telecommunications Room
A
- Houses Horizontal cross-connects
- Termination point for horizontal cabling
- Likely to house equipment like Switchers, routers, modems
5
Q
Entrance Facilities/Demar
A
- Special equpment rooms where external cabling is joined to internal
6
Q
IDC
A
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
7
Q
66 Block
A
- Older style distribution frame
- 50 rows of 4 IDC terminals
- Jumper is installed to complete connection
8
Q
110 Block
A
- 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
9
Q
BIX and Krone Distrubtion Frames
A
- Uses a single module
- Krone more common in Europe
- Use different termination blade
10
Q
Patch Panel
A
- 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
11
Q
SFP/SFP+
A
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
12
Q
QSFP/QSFP+
A
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
13
Q
WDM
A
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
14
Q
BiDi
A
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
15
Q
Cable Crimper
A
- Used to create a patch cord
- Fixes plug to cable
- Specific to connector type and cable
