Structured Cabling Systems
| Question | Answer |
|---|---|
| Importance of Structured Cabling | Scalability, Cost Efficiency, Future-Proofing, Standardization, Organization (SCEFPSO) |
| passes between the telecommunication rooms (usually on the same floor) and cross-connects to the telecommunication outlets in the work area. | Horizontal Cabling |
| The backbone system encompasses all the cabling between the telecommunications room, equipment room, entrance facilities, and buildings | Backbone Cabling |
| House equipment like routers, switches, and patch panels | Telecommunication Rooms |
| comprises all the components between the telecommunications outlet and the user’s workstation equipment or devices like computers, phones, etc. | Work Area |
| MUTOA | Multiuser Telecommunication Outlet Assembly |
| houses the telecommunication system. It can be one, or it can take over the telecom room. | Equipment room |
| Where the outdoor cable connects with the building’s backbone cabling. | Entrance facility |
| Types of Pathways | Types of Pathways |
| Large open channels for managing large quantities of cables. | Cable Trays |
| Enclosed pathways (PVC or metal) that provide protection for cables | Conduits |
| Surface-mounted channels for cables in office or commercial spaces. | Raceways |
| Large enclosed pathways, often for underground or large building applications. | Ducts |
| Cable-supporting hooks used in horizontal pathways. | J-Hooks |
| Organizational support for vertical or horizontal cables. | Racks |
| Temporary pathways used during construction. | Pipes |
| Cable management along walls in commercial spaces. | Wall-Mounted Pathways |
| Pathways built into floors to house cables in raised floor environments. | Floor Ducts |
| Used in raised floor systems or ceiling spaces for organizing cables | Underfloor/Overhead Pathways |
| Use it for runs between equipment rooms or from the telecommunications room to the wall plates. | Solid Conductors |
| It is used primarily as a patch cable between the outlet and desktop between patching equipment. The impact tool is used to terminate a wire in the patch panel. | Stranded Conductors |
| Types of Cabling Media | Types of Cabling Media |
| Common in LANs, supporting Ethernet protocols. | Copper Cables |
| Uses light as an information carrier | Fiber Optic Cables |
| Long-distance transmission with high data rates. | Single-mode |
| Shorter distances, cheaper, used within a building. | Multi-mode |
| TIA/EIA Standards | TIA/EIA-568 TIA/EIA-569 TIA/EIA-606 |
| Structured Cabling Topology | Structured Cabling Topology |
| Centralized model with a central hub (switch/router). | Star Topology |
| Used less frequently; involves a loop network | Ring Topology |
| Older system where all devices are connected to a single cable backbone. | Bus Topology |
| Combination of multiple topologies to meet different needs. | Hybrid Topology |
| Installation Process | Installation Process |
| Site survey, understanding requirements, designing the network | Planning |
| Running cables, terminating them properly. | Cable Installation |
| Certifying cables for proper performance (speed, connectivity) | Testing |
| Keep a record of cable pathways, patch panels, and wiring details | Documentation |
| Maintenance and Troubleshooting Common issues | • Signal Loss: Check for physical damage or poor connections. • Interference: Verify proper shielding. • Loose Connections: Ensure all cables are securely connected to patch panels and switches. |
| Trends in Structured Cabling | Trends in Structured Cabling |
| The move to 10Gbps and beyond | Higher Speeds and Bandwidth |
| Growing adoption of fiber optics for both backbone and horizontal cabling. | Fiber Optic Dominance |
| Automation, IoT devices, and increased reliance on cabling systems for control and communication | Smart Building Integration |
| Reduced environmental impact and energy efficiency | Green Cabling |
