Network cable CORDIAL 15583 Cat7a S/FTP (S-STP) RJ-45 to RJ-45 20 m Black

The CORDIAL 15583 is a 20 m Cat7a S/FTP (S‑STP) network patch cable with RJ‑45 connectors on both ends. It uses a CCAT 7A PUR bulk cable and HIROSE® RJ45 plugs, offering a 1000 MHz bandwidth and a robust PUR jacket designed for mobile indoor and outdoor use. The cable is developed for audio networks, lighting control and EtherSound™ systems and features a flexible AWG 26/7 conductor suitable for patching and device connections. It also supports Power over Ethernet (PoE) according to IEEE 802.3af-2003 with up to 15.4 W power delivery.

Advantages

The cable’s S/FTP double shielding reduces crosstalk and electromagnetic interference for stable high-speed data transmission. A flexible inner conductor and reelable PUR jacket combine ease of handling with mechanical durability for stage, mobile and outdoor applications. Additional properties such as flame retardancy, halogen-free materials and resistance to oil, microbes and chemicals increase safety and longevity in demanding environments.

Suitable for

• Professional LAN and server room connections
• Audio networks and EtherSound™ systems
• Lighting control and stage installations
• Mobile indoor/outdoor setups and temporary event wiring

When it may not be suitable

This cable is intended for high-performance Ethernet and specific audio/lighting networks; it may be unnecessary for simple home office or low-speed network needs where Cat5e or Cat6 cables suffice. For installations requiring higher PoE power classes or longer PoE distance than specified, a cable and power standard supporting greater wattage and distance should be chosen.

Key specifications

• Cable category: Cat7a (1000 MHz)
• Shielding: overall S/FTP (S‑STP)
• Conductor: flexible AWG 26/7
• Connectors: RJ‑45 straight male — both ends
• Length: 20 m
• Jacket material: PUR (polyurethane), black
• PoE support: IEEE 802.3af-2003, up to 15.4 W (max. channel PoE 70 m)
• Flame retardant: UL 1581 §1090/§1100 (FT2), IEC 60332-1-2
• Halogen-free: EN 50267-2-1, IEC 60754-1
• Oil and chemical resistance: IEC 60811-2-1, ICEA S-82-552, ASTM IRM 902
• Sludge resistance: NEK 606

How to use

Connect the RJ‑45 plugs to the corresponding Ethernet ports on devices such as switches, network interfaces or patch panels. Route the cable avoiding sharp bends and heavy mechanical stress; the PUR jacket allows flexible use in mobile and outdoor setups but maintain recommended bend radii to preserve performance. For PoE applications, ensure connected equipment complies with IEEE 802.3af and observe the specified maximum channel distance for power delivery.

What to consider before purchase

• Required cable category and bandwidth for your network (Cat7a, 1000 MHz)
• Length needed and routing conditions (20 m reel)
• PoE power and distance requirements (IEEE 802.3af, 15.4 W up to specified channel length)
• Environmental exposure (PUR jacket offers oil, chemical and microbe resistance)
• Compatibility with devices and connectors (RJ‑45 ports)

Usage recommendations

Use this CORDIAL Cat7a S/FTP patch cable for professional and temporary installations where enhanced shielding, mechanical durability and flexible handling are required. Verify PoE power needs and maintain correct bending radius and connector seating to ensure reliable long-term performance.
