Kramer Electronics C-UNIKAT-25 25ft Cat6a U/FTP

Product Overview

The Kramer Electronics C‑UNIKAT‑25 is a high‑performance Cat6a U/FTP networking cable designed for demanding data and video applications. With a length of 7.6 m (25 ft), it offers the flexibility needed for both indoor and outdoor installations while maintaining strict adherence to industry standards.

Key Technical Specifications

• Category: Cat6a – supports up to 10 Gbps over distances up to 100 m.
• Construction: U/FTP (Unshielded Foiled Twisted Pair) – each pair is individually foiled, providing excellent protection against crosstalk and external interference.
• Shielding: STP (Screened Twisted Pair) – the cable features a robust outer shield that further mitigates EMI/RFI.
• Conductors: Four pairs of 23 AWG copper, ensuring low resistance and high current carrying capacity.
• Connectors: Standard RJ‑45 connectors on both ends, compatible with all Ethernet devices.
• Color: Distinctive Blue, facilitating easy identification in complex cabling systems.
• Length: 7.6 m (25 ft) – ideal for short runs within a rack, wall to patch panel, or between adjacent rooms.
• Compliance: Meets TIA/EIA‑568, ISO/IEC 11801, and IEEE 802.3 standards for structured cabling.

Design Features & Construction Details

The C‑UNIKAT‑25 incorporates a layered shielding strategy:

1. Individual Foil Shielding: Each twisted pair is wrapped in a thin foil layer, reducing crosstalk and preserving signal integrity.
2. Overall STP Layer: A continuous outer shield (often braided copper or aluminum) encases the entire cable assembly, blocking external electromagnetic interference.
3. Durable Jacket: The cable is terminated with a high‑quality PVC jacket that resists abrasion, moisture, and temperature variations up to 70 °C.

Performance Characteristics

• Bandwidth: Supports frequencies up to 500 MHz, enabling smooth transmission of high‑definition video streams and large data packets.
• Crosstalk (NEXT): Maintains a minimum of -60 dB, ensuring minimal interference between adjacent pairs.
• Attenuation: Less than 3.5 dB/100 m at 500 MHz, guaranteeing signal strength over the cable’s full length.
• Return Loss: Better than -20 dB, indicating efficient impedance matching and low reflection.

Ideal Applications

The C‑UNIKAT‑25 is engineered for a wide range of networking scenarios:

• Data Centers & Server Rooms: Short runs between patch panels, switches, and servers where high bandwidth and low latency are critical.
• Broadcast & Video Production: Reliable transmission of uncompressed HD or 4K video streams over Ethernet.
• Enterprise LANs: Seamless connectivity within office buildings, ensuring consistent performance across multiple floors.
• Industrial Automation: Robust shielding protects against harsh electromagnetic environments found in manufacturing plants.
• Residential Smart Homes: High‑speed internet and media distribution between rooms or floor levels.

Installation & Deployment Tips

1. Routing: Keep the cable away from high‑power electrical cables whenever possible to reduce interference.
2. Securing: Use proper cable ties and support brackets; avoid sharp bends that could damage the foil shielding.
3. Termination: Employ certified RJ‑45 crimping tools and test with a network cable tester to verify continuity, impedance, and crosstalk compliance.
4. Labeling: The blue color aids in quick identification; consider adding descriptive labels for future maintenance.

Compatibility & Integration

The C‑UNIKAT‑25 is fully compatible with any device that accepts standard RJ‑45 connections, including:

• Ethernet switches and routers (10/100/1000 Mbps and 10 Gbps models)
• Network interface cards (NICs) in computers, servers, and media players
• IP cameras, VoIP phones, and other networked peripherals
• Video distribution systems that rely on Ethernet-based transport

Environmental & Safety Considerations

• Temperature Range: Operates effectively between -10 °C and +70 °C.
• Moisture Resistance: The PVC jacket provides adequate protection against humidity in typical indoor environments.
• Fire Safety: Meets UL94 V‑0 flammability standards, ensuring safe performance in case of accidental ignition.

Maintenance & Longevity

With proper handling and installation, the C‑UNIKAT‑25 offers a long service life. Regular inspections should focus on:

• Checking for physical damage to the jacket or shielding.
• Ensuring connectors remain clean and free of corrosion.
• Re-testing signal integrity after any major environmental changes.

Conclusion

The Kramer Electronics C‑UNIKAT‑25 delivers exceptional performance, robust shielding, and reliable connectivity in a compact 7.6 m form factor. Its Cat6a U/FTP construction makes it an ideal choice for high‑bandwidth applications ranging from enterprise networking to professional video production.
