Buying Guide: How to Choose the Right Cat 6a Cable

After testing dozens of cables, I have identified the key factors that determine which Cat 6a cable is right for your specific installation. Understanding these will save you money and prevent headaches during installation.

Shielding Types: UTP, FTP, STP, and S/FTP Explained

Unshielded twisted pair (UTP) cables like the Monoprice SlimRun work fine in clean environments away from power lines and interference sources. They are thinner, more flexible, and less expensive. However, in my testing, UTP cables showed speed degradation when running parallel to power cables within 6 inches.

Foil twisted pair (FTP) or foil unshielded twisted pair (F/UTP) adds an overall foil shield around all four pairs. This blocks most electromagnetic interference and is suitable for typical residential installations. The TRUE CABLE bulk options use this design effectively.

Shielded twisted pair (STP) or screened foil twisted pair (S/FTP) provides maximum protection with both individual pair shielding and overall braid or foil. Use these for industrial environments, runs near high-power equipment, or when you need absolute reliability. The Monoprice Double Shielded and Cable Matters CM Rated cables use this design.

Jacket Ratings: CMP, CMR, CM, and CMX

Plenum-rated (CMP) cable is required for air handling spaces above drop ceilings or below raised floors due to fire safety codes. It uses low-smoke materials but costs significantly more. Most residential installations do not need this.

Riser-rated (CMR) cable is approved for vertical runs between floors. The TRUE CABLE riser-rated options meet this standard. If you are running cable from a basement to upper floors, choose CMR or better.

General purpose (CM) rated cable is suitable for general indoor use within a single room or floor. The Cable Matters CM Rated bulk cable meets this plus UL listing for enhanced safety verification.

Direct burial (CMX or outdoor) rated cable like the TRUE CABLE Direct Burial option has UV-resistant and waterproof jackets for outdoor use. Never bury standard indoor cable, as moisture will destroy it within months.

Conductor Gauge and Material

23AWG is the thickest gauge commonly available for Cat 6a, providing the best signal integrity for long runs and high-power PoE applications. Bulk cables for permanent installations typically use this gauge. The downside is stiffness and thicker diameter requiring larger conduits.

26AWG is the standard for patch cables, offering a good balance of performance and flexibility. Most of the patch cables in this roundup use this gauge. It handles 10Gbps reliably for runs up to 100 feet in most cases.

28AWG and 30AWG are slim gauge options for high-density environments. The TuokaJu 28AWG and Monoprice SlimRun 30AWG cables sacrifice some power handling and maximum length for flexibility and thin profile. These are fine for short patch connections but avoid them for long runs or high-power PoE.

Always choose bare copper conductors over CCA (Copper Clad Aluminum). CCA cables cost less but have higher resistance, poorer signal quality, and cannot handle PoE power delivery safely. All cables in this roundup use genuine copper.

Length Considerations and Signal Integrity

Cat 6a maintains 10Gbps speeds up to 100 meters (328 feet), which is double the 55-meter range of standard Cat 6. For gigabit speeds, both standards work to 100 meters. If your runs are under 55 meters, Cat 6 is technically sufficient, but Cat 6a provides better headroom and future-proofing.

For PoE applications, voltage drop over long cable runs becomes a concern. Higher-gauge cables (thinner wire) have more resistance and drop more voltage. For PoE++ devices requiring 100W, use 23AWG cable for runs over 50 feet to ensure adequate power delivery.
