What is CAT 7 ethernet cable and CAT 7A ethernet cable ?
CAT 7 (Category 7) and CAT 7A (Category 7A) cables are high-performance Ethernet cables designed for Gigabit Ethernet and beyond. Their robust construction and stringent specifications minimize crosstalk and electromagnetic interference (EMI), making them suitable for demanding applications. Here’s a breakdown of their common uses:
1. Gigabit Ethernet Backbone
CAT 7 cables are frequently employed as patch cables within Gigabit Ethernet networks. They form a crucial part of the core infrastructure, ensuring reliable, high-speed data transmission.
2. Device Connectivity
Both CAT 7 and CAT 7A cables connect various network devices, including:
- Modems
- Routers
- Hubs
- Computers
This connectivity extends across networks of all sizes, from small home offices to large commercial installations.
3. Commercial and Industrial Environments
CAT 7 cables are built to endure challenging conditions. Their durability makes them suitable for industrial settings characterized by:
- Extreme temperatures
- UV exposure
- Moisture
- Chemical and oil contact
4. Home Networks
CAT 7 and CAT 7A cables are increasingly popular for home use, particularly for:
- High-speed internet access
- Enthusiast gaming setups
- Streaming high-definition content
- Connecting multiple smart home devices
Their high bandwidth and reduced crosstalk enhance performance in these demanding domestic applications.
5. Local Area Networks (LANs)
CAT 7 and CAT 7A cables are widely used in LAN deployments, both commercially and residentially. They provide the speed and reliability necessary for efficient network operation, especially in data-intensive environments.
CAT 7 and CAT 7A Cable Speed and Specifications
Here’s a breakdown of the speed, performance, and construction of CAT 7 and CAT 7A cables:
Speed and Performance
CAT 7 Cable:
- Speed: Supports up to 10 Gbps over 100 meters.1 While officially rated for 10 Gbps, some tests have shown potential for higher speeds (up to 40 Gbps or 100 Gbps) over shorter distances.2
- Bandwidth: Offers up to 600 MHz of bandwidth.
CAT 7A Cable:
- Speed: While also supporting up to 10 Gbps, the higher bandwidth allows for potentially greater speeds over shorter distances and better performance with future technologies.
- Bandwidth: Offers up to 1000 MHz of bandwidth.
- Enhanced Features: Designed for even better crosstalk and EMI protection, making it suitable for noisy environments.3
Construction Specifications
Both CAT 7 and CAT 7A cables share similar construction characteristics:
- Conductor: 22-23 AWG solid copper conductors.4 Solid core is essential for high-frequency performance.
- Shielding:
- Individually shielded pairs with AL/PET foil to minimize crosstalk within the cable.5
- Overall cable shielding with AL/PET foil for further protection against EMI.6
- Braided shielding around the entire cable for additional EMI protection. This robust shielding is a key differentiator of CAT 7/7A.
- Jacket: Available jacket options include:
- PVC (with UL CM, UL CMR, or FT4 fire ratings)
- PE (Polyethylene, often used for outdoor applications)7
- LSZH (Low Smoke Zero Halogen, for indoor installations where fire safety is a concern)8
CAT 7 and CAT 7A Cable Connectors, Packing, Testing, Selection, and Ordering
Here’s a comprehensive overview of CAT 7 and CAT 7A cables, covering connectors, packing, testing, selection criteria, and how to place orders:
Connectors
CAT 7 and CAT 7A cables utilize specialized connectors for optimal performance:
- GG45: The most common connector for CAT 7/7A. It’s backward compatible with RJ45 (8p8c) connectors used for CAT 5e and CAT 6, but adds four additional conductors for higher frequencies (up to 600 MHz for CAT 7 and 1200 MHz for CAT 7A).
- TERA: Another option, offering similar performance to GG45. However, TERA connectors are not compatible with standard RJ45 jacks.
Packing
To preserve the electrical integrity of CAT 7/7A cables, specialized packaging is used:
- Spools: Plastic or wooden spools are preferred over traditional reel-in-box packaging.
- Lengths: Common lengths include 100m, 300m, and 500m, but custom lengths are available.
Testing
Testing is crucial to ensure CAT 7/7A cable performance:
- Fluke Testers: Models like the DSX2-8000, DSX2-5000, and DTX-1800 are industry standards.
- Link vs. Channel Testing:
- Link: Tests the complete, installed cabling system. This is the most practical test.
- Channel: Tests a single component (e.g., the cable itself) to verify its individual performance.
- Network Analyzers: Offer precise testing across various lengths, often exceeding Fluke test requirements.
CAT 6A Cable Selection
While this section focuses on CAT 7/7A, here’s a quick guide to choosing CAT 6A:
- Size and Weight: CAT 6A is thicker and heavier than CAT 6. Consider cable tray/conduit capacity.
- Bend Radius: Requires a larger bend radius.
- Installation: More challenging due to thickness.
- EMI Shielding: Shielding quality and proper grounding are important.
- Network Infrastructure: Consider current and future network needs.
