## Summary description

ROLINE Cat8.1 S/FTP (S-STP) networking cable, 1 m length, yellow. Equipped with RJ-45 connectors on both ends with gold‑plated contacts. Shielding S/FTP provides improved protection against interference. Supports data transfer rates up to 40,000 Mbit/s, suitable for high‑speed local networks, server connections and backbone links where short, high‑performance patch cables are required.

## Long description

ROLINE 21.15.3421 is a slim, double‑shielded Category 8.1 (Class I) patch cord with screened RJ‑45 connectors on both ends. Designed for data rates up to 40 Gigabit Ethernet, the cable features bare copper conductors, gold‑plated contacts and a compact outer diameter for installations where space is limited. The cable jacket is halogen‑free, flame‑retardant and low‑smoke (LSOH), and the cord supports Power over Ethernet (PoE).
Advantages
The S/FTP (S‑STP) construction with foil‑shielded pairs and an overall braid provides robust protection against electromagnetic interference, while the molded kink protection improves durability at the connector ends. Slim 4.5 ± 0.2 mm outer diameter reduces cable bulk in dense cabling environments. Gold‑plated contacts and stranded bare copper conductors ensure reliable signal transmission for high‑speed 40 Gbit/s networks. The halogen‑free, flame‑retardant, low‑smoke jacket increases safety in installations.
Suitable for
High‑speed server and switch interconnects in data centers
Short‑reach 40 Gigabit Ethernet links
PoE deployments where power is delivered over RJ‑45
Tight cable routing and patch panels with limited space
Key specifications

How to use
Insert each RJ‑45 plug into the corresponding RJ‑45 jack on networking equipment until the latch clicks. Use the 1 m patch cord to connect switches, routers, servers or patch panels for short‑reach, high‑speed links. Ensure connectors are fully seated and routed without sharp bends to preserve the shielding and the molded kink protection; avoid excessive pulling on the cable. The cable supports plug‑and‑play PoE where applicable.
Usage recommendations
For optimal performance, use this Cat8.1 S/FTP patch cord for short copper runs within racks or between adjacent racks in data centers and keep cable bends above the recommended bend radius. Avoid exposure to direct sunlight and aggressive chemicals; verify PoE power budgets on connected equipment before deployment.
