Sigma™ Cat 8 Ethernet Cable · 40 Gbps • 2 GHz • PoE++ 100 W
The Sigma Cat 8 Ethernet Cable is precision-engineered to deliver superior networking performance, combining cutting-edge data throughput, ultra-low latency, and robust shielding to meet the demands of modern, high-speed infrastructures. Designed for both commercial and industrial networks, it sets a new benchmark in copper-based connectivity with exceptional bandwidth, interference resistance, and 8K video-ready performance.
Technical Highlights
- Data Transfer Rate: Achieves up to 40 Gbps throughput, enabling simultaneous multi-gigabit data operations with minimal packet loss.
- Latency: Microscopic delay of 1/1,000,000 second (≤ 1 µs) ensures real-time responsiveness across mission-critical systems.
- Error Correction: Equipped with advanced bit error correction (FEC) for error-free, consistent transmissions even under heavy network loads.
- Connector Type: 8P8C (RJ45) connectors with anti-crosstalk dividers and gold-plated contacts for maximum conductivity and signal fidelity.
- Resolution Support: Supports uncompressed 4K and 8K UHD video streaming with flawless synchronization and zero signal degradation.
- Shielding: Multi-layer F/FTP design with foil and braided shielding eliminates EMI and maintains stable signal performance across all channels.
- Compliance: Exceeds IEEE 802.3 standards; suitable for PoE++ (100 W) and outdoor-rated applications under harsh conditions.
- Compatibility: Fully backward-compatible with Cat 5e, Cat 6, and Cat 7 devices, auto-negotiating optimal data speeds up to 40GBASE-T.
- Bandwidth: Provides a maximum frequency response of 2 GHz (2000 MHz), optimized for data-intensive, multi-stream environments.

Frequently Asked Questions
1. What performance advantages does Sigma Cat 8 offer over Cat 6 and Cat 7?
Sigma Cat 8 operates at a maximum bandwidth of 2 GHz (2000 MHz) — quadruple that of Cat 6a — and supports data rates up to 40 Gbps. It also employs advanced shielding to minimize interference and sustain full performance across extended distances.
2. What makes Sigma Cat 8 ideal for 8K streaming and professional AV?
Its 40 Gbps throughput, combined with near-zero latency and robust shielding, allows uncompressed 8K UHD data transmission, making it ideal for broadcast facilities, live production studios, and pro AV installations.
3. Is the cable backward compatible with older network standards?
Yes. Sigma Cat 8 cables use universal RJ45 connectors, ensuring backward compatibility with Cat 5e, Cat 6, and Cat 7 devices, automatically adjusting speed to match connected equipment.
4. How does bit error correction improve reliability?
Built-in Forward Error Correction (FEC) algorithms monitor and correct minor signal deviations in real time, ensuring consistent, error-free data transfer even under electromagnetic stress or high-bandwidth operation.
5. Can Sigma Cat 8 cables handle Power over Ethernet (PoE++)?
Yes. Sigma Cat 8 supports the IEEE 802.3bt Type 4 PoE++ standard, providing up to 100 watts of power safely over Ethernet — ideal for IP cameras, access points, and automation devices.
6. What kind of shielding does Sigma Cat 8 use?
The cable features an F/FTP configuration — each twisted pair is individually foil-shielded, with an additional braided overall shield, ensuring full electromagnetic isolation from external interference.
7. Is it suitable for outdoor or industrial use?
Yes. The cable’s outdoor-rated and UV-resistant jacket options protect against temperature changes, UV exposure, and moisture, making it suitable for both indoor racks and external network runs.
8. Can it replace fiber for short-range backbone connections?
For link lengths under 30 meters, Sigma Cat 8 can deliver fiber-like performance with 40 Gbps throughput, ultra-low latency, and lower installation costs.
9. Does Sigma Cat 8 improve online gaming performance?
Absolutely. With sub-microsecond latency and EMI-resistant design, Sigma Cat 8 provides the fastest possible wired connection for competitive gaming and streaming without packet loss.
10. What testing and certification does Sigma Cat 8 undergo?
Each cable is tested for compliance with ANSI/TIA-568.2-D and ISO/IEC 11801 Class I standards, verifying return loss, insertion loss, NEXT/FEXT, and PoE++ power performance across its full operating range.
The Sigma Cat 8 Ethernet Cable defines a new class of performance in copper networking — built for engineers, gamers, and data professionals who demand speed, stability, and future-proof connectivity. Whether it’s for a 40G data center link or an 8K media workflow, Sigma Cat 8 delivers uncompromised performance where it matters most.
