Structured Cabling System

Question 1

Horizontal Cabling

Answer 1

Links work areas to Intermediate Distribution Frame (IDF), typically limited to a single floor, runs horizontally through wall, ceilings, or floors, max distance 90 meters (295 feet), multiple IDFs are needed if distance exceeds 90 meters, multiple IDFs are required when distance is more than 90 meters, and horizontal cross-connects link IDFs on the same floor.

Question 2

Work Area

Answer 2

The space where user equipment is located and connected to the network, usually via a patch cable plugged into a wall port.

Question 3

Intermediate Distribution Frame

Answer 3

A smaller distribution point used to connect user devices on a specific floor or section of a building to the main network. Usually, it is found in a telecommunication room or closet. It connects Horizontal cabling to the MDF.

Question 4

Main Distribution Frame

Answer 4

The central distribution point for the building or campus network. Typically, it is found in the main server room or entrance facility. It connects the service provider’s line to the IDFs across the building via backbone cabling.

Question 5

Demarcation Point

Answer 5

The demarcation point is the official boundary between the service provider’s network (like your internet company) and the organization’s internal network (like your home, office, or data center).

Question 6

Telecommunication Room

Answer 6

• Also called a wiring closet
• Houses IDFs and network devices (e.g. switches)
• Termination point for horizontal cabling
• Must only store network equipment (no general storage)
• Should be secured (lockable door)

Question 7

Backbone Cabling

Answer 7

• Connects IDFs to the MDF (Main Distribution Frame).
• Often runs between floors and buildings.
