Structured Cabling, ISO OSI Flashcards
Structured Cabling uses _____ to offer long term support of networks
High Performance Components
Why do we use standardized tech
Cause IT is always changing
Advantages of Structured Cabling Systems
Performance of LANs, Telecommunications, Data Systems will work predictably
Components of Structured Cabling Systems (Distributions)
Campus Distribution, Building Distribution, Floor Distribution, Telecommunications Outlet
Campus Distribution
Backbone cabling infrastructure connecting buildings on a large campus, typically using cables such as fiber optic or wireless
Building Distribution
Cabling infrastructure connecting campus distribution to floor distribution cabling
Floor Distribution
Cabling infrastructure that connects building distribution cabling to individual workstations or devices. Typically horizontal cabling running from IDF to telecommunications outlet.
Telecommunications Outlet
Endpoint of the structured cabling system providing connectivity to a specific device. Located in a wall or floor box. May include different jacks.
ISO 11801 Standard 3 Layer Model (Layers)
Horizontal Cabling, Building Backbone Cabling, Campus Backbone Cabling
Horizontal Cabling
Provides telecommunications services between floor distribution and Telecommunications outlet (Mostly copper cable)
Building Backbone Cabling
Provides telecommunications services between floors on a building. Connects building distribution to floor distributions
Campus Backbone Cabling
Connects building, connects two or more Building distributions (Almost always fiber optic)
Hardware used in cabling methods
Fibre Cables, Copper Cables, Wall sockets, cables, patch panels, patch cords, Standing Rack.
Notation for Communications Cabinet
“U” known as rack unit, equivalent to 445mm. 42U Rack will accept 42 one unit U patch.
Channel limit
100m for category 5,6,7 based cabling systems. Link should be limited to 90m.
Difference between the 2 allows patch cords to connect equipment at patch panel and devices from Telecommunications Outlet.
Communications Cabinets
used to house termination of backbone and horizontal cabling subsystems + electronics. Housed in Telecommunications Room.
Telecommunications Room
Void of direct sunlight, toilets, emergency escapes, areas prone to flooding, and areas containing fire extinguishers.
Communications Cabinets must avoid
force majure, unsecurity, vibration, dust, humidity
