Network Infrastructure Cabling refers to the structured system of cables, connectors, and hardware used to connect computers, servers, switches, routers, and other network devices within a building or campus. It forms the physical backbone of an IT network.
Main Types of Network Cabling
- Twisted Pair Cable
- Most common for LAN networks.
- Types: Cat5e, Cat6, Cat6A, Cat7.
- Used for Ethernet connections between devices and switches.
- Fiber Optic Cable
- Uses light to transmit data.
- Very high speed and long-distance capability.
- Types: Single-mode fiber (SMF) and Multi-mode fiber (MMF).
- Commonly used for backbone connections, data centers, and inter-building links.
- Coaxial Cable
- Older technology, still used in some CCTV and broadband systems.
Key Components of Structured Cabling
- Patch Panels
- Network Racks / Cabinets
- Patch Cords
- Cable Trays and Management Systems
- Faceplates and Information Outlets
Structured Cabling Subsystems
- Entrance Facility – Where external network enters the building.
- Equipment Room – Houses servers, core switches, and storage.
- Backbone Cabling – Connects floors or buildings.
- Telecommunications Room (TR) – Distribution point on each floor.
- Horizontal Cabling – Cabling from TR to user workstations.
- Work Area – End-user network outlets.
Benefits
- Organized and scalable network.
- Easier maintenance and troubleshooting.
- Supports high-speed data transmission.
- Future-ready for upgrades.
Typical Use Cases
- Office networks
- Data centers
- Banks and financial institutions
- Campus networks
- Industrial facilities
