Optimize your data center and enterprise networking with our high-performance CAT8.1 Dual-Shield Riser Ethernet Cable, engineered for ultra-fast 40GBASE-T speeds up to 30 meters and superior EMI protection in vertical riser installations. Featuring S/FTP double shielding (foil per pair + overall braid), heavy-duty 23 AWG solid bare copper conductors, and a flame-retardant UL-rated CMR PVC jacket, this shielded CAT8 riser cable ensures minimal attenuation, cooler PoE++ operation, and compliance with riser fire codes for vertical shafts and in-wall runs—ideal for short vertical switch-to-switch links, multi-story data center interconnects, equipment room risers, and any high-speed vertical setup demanding reliability, bandwidth up to 2,000MHz, and backward compatibility with standard RJ45 connectors. Designed for the unique scenario of short vertical runs requiring maximum copper performance with fire safety, this exceptionally rare cable combines eight premium features: CAT8.1 Class I performance (2,000MHz), CMR fire rating for vertical installations (highly uncommon to CAT8), S/FTP dual shielding (mandatory for CAT8), heavy-duty 23AWG conductors, 40GBASE-T capability up to 30m, 25GBASE-T support, 1000ft spool (2x typical CAT8 length), and standard RJ45 compatibility. The S/FTP shielding provides individual foil on each pair PLUS an overall tinned-copper braid—delivering pristine 40Gb signal integrity in electrically noisy riser environments. Exceeding ISO/IEC 11801 Class I and ANSI/TIA-568.2-D Category 8 specifications with UL-CMR certification, it's the ultimate specialty solution for short vertical runs requiring both maximum copper ethernet performance and fire-safe compliance. Key Features Advanced S/FTP double shielding for maximum EMI/RFI protection Individual foil wrap on each twisted pair for superior isolation Overall tinned-copper braid shield encases the entire cable Mandatory shielding for CAT8.1 Class I performance Eliminates EMI/RFI interference and alien crosstalk Pristine signal integrity in noisy riser environments Heavy-duty 23 AWG solid bare copper conductors (optimal for CAT8) Low resistance for efficient, cooler PoE++ operation Reduced attenuation for reliable 40Gb/s data transmission Optimal gauge for short to medium distance vertical runs Ultra-high 2,000MHz (2GHz) bandwidth - CAT8.1 Class I specification The absolute highest copper Ethernet specification available Supports 40GBASE-T up to 30 meters (cutting-edge performance) Supports 25GBASE-T up to 30 meters (emerging standard) Supports 10GBASE-T for full backward compatibility PoE++ (IEEE 802.3bt) compatible for powered devices UL-rated CMR (Communications Riser) flame-retardant PVC jacket Meets non-plenum riser fire-code requirements Safe for vertical shafts and in-wall installations between floors Fire compliance for multi-story buildings EXCEPTIONALLY RARE: CMR rating for CAT8 (most CAT8 is non-rated or LSZH) Class-I RJ45 compatibility for easy integration Seamlessly works with standard Cat6A/7/8 modular plugs Pairs perfectly with Cat8 field-termination connectors Standard RJ45 termination (CAT8.1 advantage over CAT8.2) Sequential foot markers for quick length tracking Hassle-free installations in vertical runs 1000ft spool - 2x typical CAT8 spool length (usually 500ft) Professional-grade for mission-critical infrastructure Ideal Applications Short vertical runs in multi-story data centers (floor-to-floor
