Frequently Asked Questions
1. What makes Sigma Cat 8 different from previous Ethernet standards?
Sigma Cat 8 operates at 2000 MHz — four times the frequency of Cat 6a — and delivers up to 40 Gbps over standard RJ45 connectors with precision-engineered F/FTP shielding for EMI-free transmission.
2. Does it support Power over Ethernet applications?
Yes. Sigma Cat 8 is fully compliant with IEEE 802.3bt Type 4 (PoE++) and supports up to 100 W of power for access points, PTZ cameras, and industrial lighting systems.
3. Can it be used for outdoor or industrial deployments?
Outdoor-rated jackets offer UV, moisture, and temperature resistance for direct-sunlight and exposed environments, ensuring longevity in industrial settings.
4. How does the bit error correction feature work?
Advanced Forward Error Correction monitors signal integrity and automatically repairs bit-level anomalies to maintain consistent throughput under noise or load.
5. Is Sigma Cat 8 compatible with existing hardware?
Absolutely. It uses standard RJ45 interfaces and auto-negotiates link speeds with Cat 5e, Cat 6, and Cat 7 devices for maximum flexibility during upgrades.
6. What is the maximum distance for 40 Gbps performance?
The Sigma Cat 8 cable supports full 40 Gbps operation up to 30 meters. Beyond that range, it maintains 10 Gbps or 25 Gbps depending on device negotiation.
7. Does Sigma Cat 8 support 8 K video and real-time AV streaming?
Yes. Its 40 Gbps bandwidth and FEC technology enable uncompressed 8 K video delivery and synchronized audio/video streaming without packet loss.
8. Can it replace fiber for short network links?
For runs under 30 meters, Sigma Cat 8 provides fiber-class latency and bandwidth without the need for optical transceivers or complex terminations.
9. What testing standards does Sigma Cat 8 meet?
Each cable undergoes testing for insertion loss, NEXT/FEXT, return loss, impedance stability, and PoE++ thermal performance to meet ANSI/TIA-568.2-D and ISO/IEC 11801 Class I specifications.
10. Why is Sigma Cat 8 the best choice for future-proof networks?
Its combination of 40 Gbps speed, 2 GHz bandwidth, and 100 W PoE++ support ensures compatibility with emerging IoT, cloud, and data-center protocols for the next decade of connectivity.
Upgrade to the Sigma Cat 8 Wire Cable and experience a new standard of network performance — from 8 K streaming and real-time control to data-center-grade bandwidth and PoE++ power delivery. It’s not just Ethernet — it’s your network’s fastest, most reliable connection to the future.
