Modern businesses rely on robust network infrastructure to maintain operations, support communication, and enable data sharing. At the heart of this infrastructure are the various types of network cables that build the foundation of any structured cabling system. These cables, often hidden behind walls or running through ceiling spaces, determine network performance, reliability, and future scalability.
Industry statistics reveal that properly designed structured cabling can reduce network downtime by up to 50%. With businesses becoming increasingly dependent on digital technologies, the importance of selecting the right network cables cannot be overlooked. Therefore, understanding the different cable types is essential for making informed decisions.
The global Structured Cabling Market size is estimated to be USD 11.7 billion in 2022 and is projected to reach USD 15.0 billion by 2027. This growth reflects the increasing demand for reliable, high-speed connectivity in various sectors, including healthcare, education, finance, and manufacturing. As data transmission requirements continue to evolve, so do the cables that make this transmission possible.
What is Structured Cabling?
Structured cabling is a comprehensive infrastructure of cables and associated hardware that provides a systematic approach to network installation and management. Unlike point-to-point cabling, which creates direct connections between specific devices, structured cabling creates an organized, flexible foundation that can accommodate changes and growth.
The key components of a structured cabling system include:
- Entrance facilities where external telecommunications services enter the building
- Equipment rooms housing servers and network devices
- Telecommunications rooms with connecting hardware
- Backbone cabling connecting entrance facilities, equipment rooms, and telecommunications rooms
- Horizontal cabling running from telecommunications rooms to individual work areas
- Work area components such as wall plates and patch cords
When properly implemented, structured cabling follows standards established by organizations like the Telecommunications Industry Association (TIA) and the Electronic Industries Alliance (EIA). These standards ensure consistency, compatibility, and performance across different installations.
4 Major Types of Network Cables Used in Structured Cabling
Here are the various types of cables that form the physical layer of these systems:
-
Twisted Pair Copper Cables
The most common type of network cable used in network cable installation Toronto and worldwide is twisted pair copper cable. As the name suggests, these cables contain pairs of copper wires twisted together to reduce electromagnetic interference.
Unshielded Twisted Pair (UTP)
UTP cables are the workhorses of modern networks, especially in office environments. These cables contain four pairs of twisted copper wires inside a single jacket, without additional shielding. The twisting itself provides natural protection against interference, making these cables cost-effective and easy to install.
UTP cables are categorized by their performance capabilities:
- Cat5e: Supports speeds up to 1 Gbps with a bandwidth of 100 MHz
- Cat6: Supports speeds up to 10 Gbps (at shorter distances) with a bandwidth of 250 MHz
- Cat6a: Supports speeds up to 10 Gbps (at full 100m distances) with a bandwidth of 500 MHz
- Cat7: Supports speeds up to 10 Gbps with a bandwidth of 600 MHz
- Cat8: Supports speeds up to 40 Gbps with a bandwidth of 2000 MHz
Cat5e remains widely used for general office networking, while Cat6 and Cat6a are becoming standard for new installations. Cat7 and Cat8 are primarily used in data centers and high-performance computing environments.
Benefits of UTP cables include:
- Cost-effectiveness compared to other cable types
- Easy installation and termination
- Flexibility and small diameter make them easier to route
- Sufficient performance for most business applications
When implementing network cabling services, UTP cables are typically the default choice unless specific environmental or performance requirements dictate otherwise.
Shielded Twisted Pair (STP)
STP cables contain additional shielding around the twisted pairs, offering better protection against electromagnetic interference. This makes them ideal for environments with significant electrical noise or applications requiring greater security.
Different shielding configurations exist:
- Foil shielded (F/UTP): Overall foil shield around all pairs
- Screened shielded (S/FTP): Overall braid shield with individual foil shields around each pair
- Fully shielded (SF/UTP): Combined braid and foil overall shield
STP cables are recommended for:
- Industrial environments with heavy machinery
- Areas with high electromagnetic interference
- Installations near power lines or elevators
- Applications requiring additional security against signal leakage
While offering better protection, STP cables are more expensive, less flexible, and require proper grounding during installation. Professionals often recommend STP for specific problematic areas rather than entire installations.
2. Fiber Optic Cables
As data transmission needs increase, fiber optic cables are becoming increasingly common in structured cabling services. Instead of using copper to transmit electrical signals, fiber optic cables use glass or plastic fibers to transmit data via light pulses.
Multimode Fiber (MMF)
Multimode fiber cables have a larger core diameter (typically 50 or 62.5 microns) that allows multiple light modes to propagate. This makes the light signals disperse and degrade over distance, limiting their effective range.
Multimode fiber is classified by its performance:
- OM1: Legacy orange or gray cable supporting 1 Gbps up to 300m
- OM2: Orange cable supporting 10 Gbps up to 82m
- OM3: Aqua cable supporting 10 Gbps up to 300m or 100 Gbps up to 100m
- OM4: Aqua cable supporting 10 Gbps up to 550m or 100 Gbps up to 150m
- OM5: Lime green cable optimized for wavelength division multiplexing
Multimode fiber is ideal for:
- Campus environments
- Building-to-building connections (under 500m)
- Data centers
- Backbone cabling within a building
The cost of multimode fiber has decreased significantly, making it more accessible for medium-sized businesses seeking future-proof network cabling.
Single-mode Fiber (SMF)
Single-mode fiber has a much smaller core diameter (typically 8-10 microns) that allows only one light mode to propagate. This eliminates the signal degradation caused by modal dispersion, allowing for much longer transmission distances.
Single-mode fiber cables:
- Can transmit data over distances up to 40km without significant signal loss
- Support higher bandwidths than multimode
- They are typically yellow-jacketed for easy identification
- Cost less per meter but require more expensive optical equipment
Single-mode fiber is recommended for:
- Long-distance connections between buildings or campuses
- Telecommunications and internet service provider networks
- Metropolitan area networks
- Applications requiring the highest bandwidth capacity
Single-mode fiber is often installed even when current requirements don’t demand it, as the cable itself represents a small portion of overall installation costs and provides future-proofing.
3. Coaxial Cables
Although less common in new installations, coaxial cables still play a role in certain aspects of structured cabling. These cables consist of a center conductor surrounded by insulating material, a metallic shield, and an outer jacket.
The primary types of coaxial cables used in networking include:
- RG-6: Used primarily for cable television and satellite signals
- RG-59: Used for lower frequency applications and short-distance video
- RG-11: Thicker cable used for longer runs and higher frequency applications
Coaxial cables are typically used for:
- Cable modem connections
- Security camera installations
- Legacy networks using DOCSIS standards
- Specialized applications requiring resistance to signal interference
While Ethernet has largely replaced coaxial cabling for general networking, understanding these cables remains important for comprehensive network cabling services, particularly when integrating with existing systems or specific applications.
4. Specialty and Industrial Cables
Beyond standard network cables, certain environments require specialized cabling solutions to withstand harsh conditions or meet specific requirements.
Direct Burial Cables
These cables feature additional waterproof jacketing and are designed to be buried underground without conduit. They’re commonly used for:
- Campus connections between buildings
- Outdoor networking in parks or public spaces
- Connections to outbuildings or external facilities
Plenum-Rated Cables
Plenum-rated cables have special fire-retardant jackets that produce minimal smoke and toxic fumes when burned. They’re required by building codes for installation in plenum spaces (areas used for air circulation in heating and air conditioning systems). Network cable installation Toronto experts must use plenum-rated cables when running through ceiling spaces in commercial buildings.
Armored Cables
Armored cables include additional metal shielding or armor to protect against physical damage. They’re used in:
- Industrial environments where cables might be crushed
- Areas with potential rodent damage
- Locations where cabling might be exposed to physical threats
Direct-Attach Copper (DAC) Cables
These are pre-terminated assemblies used primarily in data centers for short connections between network devices. They offer high performance at lower costs than fiber alternatives for these specific applications.
How to Select the Right Cable for Your Network?
Choosing the appropriate network cables for your structured cabling depends on several factors:

FAQs
How long do network cables typically last before needing replacement?
Quality network cables installed by professional network cabling services can last 15-20 years in standard office environments. However, technological advancements often make upgrading desirable before physical deterioration occurs. Cables in harsh environments (extreme temperatures, moisture, or physical stress) may require replacement sooner. Regular testing can help identify degradation before it affects performance.
Can I mix different categories of cable in my network infrastructure?
Yes, different cable categories can coexist within a network, but the overall performance will be limited by the lowest-category component. For example, connecting a Cat6a patch panel to a Cat5e horizontal cable will only deliver Cat5e performance. When implementing structured cabling, it’s best to maintain consistent performance categories throughout specific network segments.
Is wireless technology making structured cabling obsolete?
No, wireless and wired networks complement rather than replace each other. While wireless provides mobility and convenience, structured cabling delivers superior reliability, security, and performance for fixed workstations and critical applications. Modern businesses typically implement both, with backbone infrastructure and critical connections relying on network cable installation Toronto professionals to provide robust wired connectivity.
How do I know if my existing network cabling needs an upgrade?
Signs that indicate your cabling may need upgrading include: frequent network slowdowns or dropouts, inability to support newer applications, visible cable damage, or cabling installed more than 15 years ago. If your business is experiencing any of these issues or planning to implement bandwidth-intensive applications, consider consulting with structured cabling services professionals for an assessment of your current infrastructure.
