Cable Distribution Systems (obj 2.4) Flashcards
(22 cards)
What is a Cable Distribution System?
An organized system connecting network backbone to end users via distribution frames
What is the design principle for Cable Distribution Systems?
Hierarchical for logical and functional placement within buildings
What is the Demarcation Point in a Cable Distribution System?
Location at which the ISP connection ends and network infrastructure begins
What does the Demarcation Point signify?
Marks entrance of WAN into facility and shifts responsibility to organization
What is the purpose of the Main Distribution Frame (MDF)?
Primary starting point for interior cabling distribution
What does the Main Distribution Frame house?
Main point of presence router and backbone switch
What is the role of the Intermediate Distribution Frame (IDF)?
Branches out from MDF to serve smaller areas
What does the Intermediate Distribution Frame contain?
Edge switches for local connections
What are Cable Trays?
A unit or assembly of units that form a rigid structural system to support cables
What are the two types of Cable Trays?
- Horizontal – installed in drop ceilings or beneath raised floors
- Vertical – minimizes vertical cable crossings between floors
What are the various types of racks in Cable Distribution Systems?
- 2-post – for lighter equipment
- 4-post – for heavier equipment
- Wall-mounted – space-saving for smaller equipment
- Rack enclosures – for high-value equipment
What is the function of Patch Panels?
Organize and facilitate connections within network infrastructure
How do Patch Panels utilize both sides?
- Front – network jacks (RJ-45 network ports)
- Back – 110 punchdown block
What is a 110 Block?
A type of punchdown block used for voice and data applications relying on CAT 5 or newer networks
What tool is used to install a 110 Block?
Punchdown tool
Why are Patch Panels preferred over direct connections?
For network maintenance and port protection
What do Fiber Distribution Panels facilitate?
Fiber connections without punchdown blocks
What types of connectors are used in Fiber Distribution Panels?
- SC
- LC
- ST
- MTRJ
What is the Cable Distribution Process?
Computer connected to wall jack using straight-through patch cable
What happens to the cable after it connects to the wall jack?
Cable runs through walls, ceilings, or raised floor to intermediate distribution frame
What is the advantage of breaking up long cable runs into multiple pieces?
Flexibility and ease of repair
How is troubleshooting facilitated in Cable Distribution Systems?
By multiple connection points, avoiding full cable reruns for minor issues
