High-performance Network Cat6 Network Cable

Increased Bandwidth: Cat6a network cables can support data rates of up to 10 Gbps at a maximum bandwidth of 500 MHz. This high bandwidth makes them ideal for modern networks, including data centers and high-speed LAN environments.

Reduced Crosstalk: Cat6a cables have tighter twists and additional shielding, which significantly reduce crosstalk and interference between adjacent cables. This ensures a more stable and reliable data transmission, even in high-density network setups.

Longer Cable Runs: Cat6a cables can support longer cable runs compared to standard Cat6 cables. They are capable of maintaining 10 Gbps data speeds up to 100 meters (about 328 feet).

Backward Compatibility: Cat6a cables are backward compatible with lower category cables (e.g., Cat5e and Cat6), so you can use them in mixed networks with various devices and equipment.

Shielding Options: Cat6a cables are available in both Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) configurations. STP cables provide better protection against electromagnetic interference (EMI) and external noise.

Future-Proofing: Installing Cat6a cables ensures that your network infrastructure is well-prepared to handle future advancements in network technologies without the need for immediate upgrades.

Cat6 Network Cable with Standard Copper Conductor

Gauge: The copper conductors in Cat6a cables typically have a gauge size of 23 AWG (American Wire Gauge). This thicker wire helps reduce resistance and signal loss, allowing for better performance at higher frequencies.

Twisted Pair Configuration: Cat6a network cables consist of four twisted pairs of copper conductors. Each pair is tightly twisted together to reduce crosstalk and electromagnetic interference, which can improve signal integrity and transmission quality.

Solid or Stranded Conductors: Cat6a cables are available in two main conductor types: solid and stranded. Solid conductors are used for in-wall installations, where the cable remains fixed, while stranded conductors are more flexible and suitable for patch cables that require frequent bending and movement.

Insulation: The copper conductors are insulated with high-quality materials to prevent signal interference and ensure the integrity of the transmitted data.

Shielding: Cat6a cables can come with different levels of shielding to protect against electromagnetic interference. Shielded Twisted Pair (STP) cables have an overall foil or braided shield that covers all four pairs, while Unshielded Twisted Pair (UTP) cables do not have an overall shield but rely on individual pair shielding.

Jacket Material: The outer jacket of Cat6a cables is typically made of PVC (Polyvinyl Chloride) or LSZH (Low Smoke Zero Halogen) materials. LSZH jackets are preferred in situations where fire safety and low smoke emissions are crucial.

Compliance: Cat6a copper conductors must meet the performance standards defined by TIA/EIA-568-B.2-10 or ISO/IEC 11801:2002 Class Ea, which specify the requirements for the cables to achieve 10 Gbps data transmission up to 100 meters (about 328 feet).

Cat6 Network Cable Features Minimum EMI and Crosstalk

Electromagnetic Interference (EMI):

STP Cat6a network cables provide superior EMI protection with an overall foil or braided shield, minimizing electromagnetic radiation and preventing external interference.

UTP Cat6a cables use internal twisted pair design to mitigate EMI but are more susceptible to external interference compared to STP cables.

Cat6a standard ensures EMC requirements are met, although it doesn’t specify an exact minimum EMI value.


Crosstalk is interference between adjacent twisted conductors in Cat6a cables.

Two main types: “NEXT” (Near-End Crosstalk) and “FEXT” (Far-End Crosstalk).

Cat6a standard defines minimum performance for NEXT and FEXT at various frequencies (specified in dB) to ensure reliable data transmission.

E.g., at 100 MHz, minimum NEXT performance is around -64 dB, and at 500 MHz, it’s around -49 dB. Minimum FEXT performance at 100 MHz is typically -57 dB, and at 500 MHz, it’s around -39 dB.

Cost-effective Solution

Implementing a cost-effective Cat6a solution involves balancing performance and budget considerations. Cat6a cables offer high-speed data transmission and future-proofing advantages, making them a wise investment for reliable networks. To optimize cost-effectiveness, assess network needs and consider alternatives like Cat6 or Cat5e for lower speeds. Bulk purchasing and competitive pricing help reduce costs, while professional installation ensures proper termination and minimizes rework risk. Plan for future growth and optimize cable lengths to maximize Cat6a benefits within budget. A thoughtful approach lets businesses enjoy high-performance networking without overspending.


Category 6 network cable is highly favored in the rapidly advancing network industry due to its outstanding performance and cost-effectiveness. It meets the demand for high-speed data transmission and low crosstalk, while also being future-proof for upcoming high-speed developments. This makes it an ideal choice for medium-sized enterprises and data centers, ensuring efficient and reliable network transmission.
