Professional FAQ
1. What is the difference between Sigma Cat 8 and standard Cat 6/7 cables?
Sigma Cat 8 operates at a frequency of 2 GHz (2000 MHz) — four times higher than Cat 6a — allowing 40 Gbps data transfer with superior EMI protection through foil and braid shielding (F/FTP). It is built for next-generation infrastructure beyond 10G Ethernet.
2. Can Sigma Cat 8 handle Power over Ethernet (PoE++) devices?
Yes. It fully supports IEEE 802.3bt Type 4 PoE++ standard with up to 100 watts of power delivery, making it ideal for high-power devices like PTZ cameras, Wi-Fi 6/6E APs, and PoE lighting.
3. How does Sigma Cat 8 achieve ultra-low latency?
Through enhanced signal geometry, tight twist ratios, and advanced foil isolation, Sigma Cat 8 minimizes propagation delay and reduces latency to under one microsecond for real-time applications.
4. What environments can Sigma Cat 8 be used in?
The cable is available in PVC (CM) for indoor use, LSZH for low-smoke environments such as data centers, and UV-rated jackets for outdoor and industrial deployments.
5. Does Sigma Cat 8 support 8 K and 4 K video transmission?
Yes. The 40 Gbps bandwidth and FEC-enabled data integrity allow stable 8 K and 4 K video streaming with no frame drops or compression loss.
6. Is it backward-compatible with older Ethernet standards?
Absolutely. Sigma Cat 8 uses standard RJ45 connectors and is compatible with Cat 5e, Cat 6, and Cat 7 hardware, negotiating the maximum supported speed automatically.
7. Can Sigma Cat 8 replace fiber for short runs?
For distances under 30 meters, Sigma Cat 8 can deliver fiber-like bandwidth and latency performance without the complexity and cost of optical transceivers.
8. How is signal integrity maintained at 2000 MHz?
Each twisted pair is foil-wrapped and surrounded by an overall braid. This architecture creates 360° electromagnetic containment, reducing alien crosstalk (A-XT) and external interference by over 90 dB.
9. Is Sigma Cat 8 suitable for professional audio over IP?
Yes. With bit-perfect packet handling and sub-microsecond latency, Sigma Cat 8 is ideal for Dante™, AES67, AVB, and Milan audio networks used in recording studios and broadcast facilities.
10. What quality testing is performed before shipment?
Every Sigma Cat 8 cable is tested for insertion loss, return loss, NEXT/FEXT attenuation, impedance stability, and PoE++ load endurance to guarantee compliance with ANSI/TIA-568.2-D and ISO/IEC 11801 Class I standards.
Upgrade your infrastructure with the Sigma Cat 8 Wire Cable — the pinnacle of copper Ethernet technology. Engineered for tomorrow’s networks, it delivers lightning-fast transfer speeds, superior EMI immunity, and rock-solid stability for mission-critical applications.
