Organized system to connect the network’s backbone in MDF to the IDF and to end user’s wall jacks
Cable Distribution Systems
Location at which the Internet service provider’s connection ends and the network infrastructure and cabling begin
Demarcation Point
Servers as the main starting point for all interior cabling that will be distributed throughout the facility
Main Distribution Frame (MDF)
Unit or assembly of units that form a rigid structural system to secure the cables and raceways used by the cables as they go across the building|
Horizontal
Drop ceiling/under a raised floor
Vertical
Vertical cross-connect
Cable Tray
Designed to hold various devices like switches, routers, patch panels, and servers to facilitate efficient space management and easy access for ongoing network maintenance| 2-post Rack, 4-post Rack, Wall-mounted Rack, Rack Enclosure
Racks
Designed with two vertical posts and is used for lighter equipment or for patch panels and network cabling in telecommunications setups
2-post Rack
Designed with four vertical posts and offers enhanced stability and support that makes it ideal for heavier equipment
4-post Rack
Space-saving solution used for smaller network equipment and is ideal for environments with limit floor space or for housing peripheral network components
Wall-mounted Rack
Fully enclosed rack with sides, doors, and a top that offers a secure and protected environment for high-value equipment
Full Cabinet Rack/ Rack Enclosure
Device or unit featuring a number of jacks for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient and flexible manner |
Patch Panel (Front side)
Network jacks
RJ-45 networks ports | Patch Panel (Back side)
110 punchdown block
Patch Panel
Type of punchdown block for both voice and data apps that rely on CAT 5 or newer copper-based networks | always connect the wall jack’s cable to a patch panel
110 Block
Uses fiber connectors like SC, LC, ST, or MTRJ to make connections | can also act as converters to convert one type of fiber connection to another
Fiber Distribution Panel
Cable Distribution System
A setup that connects the main network to users through cables and wall jacks.
Demarcation Point
The spot where the internet provider’s cable ends and your network starts.
Main Distribution Frame (MDF)
The main network room that connects everything in the building.
Intermediate Distribution Frame (IDF)
A smaller network room on each floor that connects to the MDF.
Cable Trays & Cross-Connects
Trays guide cables across ceilings or floors. Cross-connects move cables between floors.
Racks
Metal stands that hold network gear like switches and routers.
Patch Panel
A board with many ports to plug in cables and keep them neat.
Punchdown Block & Tool
Used to attach copper wires safely and cut off the extra part.
Fiber Distribution Panel
Used for fiber cables to connect or change fiber types easily.
Data Path
Switch → Patch panel → Wall jack → Computer.
This makes fixing or moving cables easy.
A tool used to find or trace network cables through walls or patch panels
Toner probe/fox and hound
Ensure consistent and reliable power delivery for networking equipment, infrastructure, and environments | uninterruptible power supply, power distribution unit, generator, managing power loads, understanding voltage considerations
