StarTech.com CAT8 S/FTP Snagless Patch Cable 25G/40G LSZH - White - 2m to 15m

The StarTech.com White CAT8 S/FTP Snagless Patch Cable 25G/40G LSZH is built for IT professionals and network engineers who need to run 25G or 40G Ethernet in environments where cable quality and safety compliance matter. It uses S/FTP shielding with per-pair aluminum-mylar foil and tinned copper braid to suppress EMI in dense or sensitive installations, and its LSZH flame-retardant jacket meets the safety requirements of poorly ventilated and enclosed spaces such as industrial settings, trains, and residential builds governed by fire codes.

• 25G/40G throughput at 2000 MHz — The cable is rated for 25/40GBASE-T networks operating at up to 2000 MHz maximum frequency, delivering up to four times the throughput capacity of Cat6a.
• S/FTP shielding with per-pair foil and braid — Each twisted pair is individually wrapped in aluminum-mylar foil and tinned copper braid, with an outer S/FTP shield, giving strong protection against EMI in high-density or electrically noisy environments.
• Pure bare copper wire for consistent signal — 26AWG pure bare copper conductors provide low resistance and reliable transmission with minimal signal loss across different operating environments.
• PoE++ support up to 100W — It supports Power over Ethernet up to 100W (IEEE 802.3bt Type 4), making it suitable for powering high-draw PoE devices such as access points, PoE switches, and IP cameras.
• LSZH jacket for enclosed and regulated spaces — The Low Smoke Zero Halogen flame-retardant jacket emits minimal smoke and toxic fumes if exposed to extreme heat or fire, enabling compliant installation in aircraft, trains, industrial settings, and residential builds.
• ETL verified to ANSI/TIA-568.2-D — Independent ETL testing confirms compliance with insertion loss, return loss, and crosstalk limits under ANSI/TIA-568.2-D, and each cable is individually Fluke channel tested before shipping.

• ✓ Connects directly to 25G and 40GBASE-T switches and networking devices via standard RJ-45 ports.
• ✓ Compatible with Network Attached Storage (NAS), Storage Area Networks (SANs), and SFP modules that accept RJ-45 Cat8 patch cords.
• ✓ Backward compatible with Cat 6, Cat 6a, Cat 5, and Cat 5e infrastructure — plugs into existing RJ-45 ports without adapters.
• ✓ Supports PoE++ devices (IEEE 802.3bt Type 4) up to 100W, including PoE switches, access points, and IP cameras.
• Note: The LSZH jacket is specifically suited to enclosed or poorly ventilated spaces (trains, aircraft, industrial settings, residential builds with fire-code requirements); standard PVC-jacketed cable may be sufficient in open, well-ventilated rack environments.
• ✗ Not designed for outdoor or direct-burial use — no outdoor-rated jacket is specified for this cable.

Best for:

• Enterprise and data-centre teams building or upgrading to 25G/40GBASE-T switching infrastructure who need verified Cat8 performance.
• Installers working in enclosed or regulated spaces — trains, aircraft, industrial facilities, or residential builds where LSZH flame-retardant jackets are required by code.
• High-density rack environments with significant EMI where per-pair S/FTP shielding and the overall braided shield are needed for reliable signal integrity.
• PoE++ deployments requiring up to 100W delivery to access points, IP cameras, or other high-draw powered devices.
• Organisations that require certified, tested cabling — ETL verification to ANSI/TIA-568.2-D and individual Fluke channel testing provide documented compliance.

Trade-offs:

• Outdoor or direct-burial runs — no outdoor-rated jacket is specified, so it is not suited to exposed exterior or underground installations.
• Standard home or office 1G networks that do not benefit from Cat8 performance — a lower category cable at lower cost would meet those requirements.
• Very long horizontal runs — as a patch cable it is designed for equipment-room and patch-panel connections; structured cabling runs from wall to panel are a separate product type.

Connect to a 25/40Gbps switch or networking device using this Snagless S/FTP Category 8 Ethernet Cable. The 2000MHz maximum frequency enables up to four times higher throughput than Cat6a.

Pure Bare Copper Wire
Our Snagless Cat8 Cables are designed for long-lasting performance. The 4-Pair Shielded and Foiled Twisted Pair (S/FTP) construction utilizes 26AWG pure bare copper wire for improved conductivity and low resistance, ensuring reliable transmission and minimal signal loss. Pure bare copper wiring offers consistent performance characteristics across different environments. Each pair is shielded in aluminum-mylar foil and tinned copper braid for enhanced EMI protection.

Durable Construction
The Cat8 Ethernet Cable features snagless 50-micro gold-plated connectors that enable a precise fit to minimize wear and are rated beyond 750 connector mating cycles. The flexible Low Smoke Zero Halogen (LSZH) flame-retardant jacket emits low smoke and toxic fumes when exposed to extreme heat or in the event of a fire. This enables safer installations in poorly-ventilated areas including some industrial settings, self-contained environments such as trains and aircraft, as well as residential settings where compliance with building codes must be considered. The cable is rated to withstand -/+90-degree bends and routes well in confined spaces.

Versatile Dependability
The Shielded Cat8 Patch Cord is ideal for high-density 25/40GBASE-T networks and supports up to 100W output to Power over Ethernet (PoE++) devices. Establish connectivity to 25G/40G switches, Network Attached Storage (NAS), Storage Area Networks (SANs), and SFP modules. It facilitates reliable throughput and power to low-latency and critical PoE devices, including PoE switches, access points, and IP cameras.

StarTech.com Cat8 Ethernet Cables are ETL Verified to meet ANSI/TIA-568.2-D standards, ensuring peak performance for high-speed 25G/40G applications. Independent testing confirms compliance with strict insertion loss, return loss, and crosstalk limits, maintaining stable signal transmission over longer runs. The S/FTP shielding is verified for EMI resistance, for guaranteed reliability in demanding environments. Backward compatibility with Cat 6/6a and Cat 5/5e standards ensure seamless integration into existing network infrastructures.
