## Summary description

ROLINE model 21.15.3436 is a 0.3 m Cat8.1 network patch cable in green with S/FTP (S-STP) shielding and RJ-45 connectors on both ends. Gold-plated contacts support up to 40,000 Mbit/s data rates. Compact and shielded design reduces interference, suitable for high-speed short-distance connections in data centers, server racks and professional network setups.

## Long description

ROLINE 21.15.3436 is a slim, double-shielded Category 8.1 (Class I) patch cord with screened RJ-45 connectors on both ends. The cable supports data rates up to 40 Gbit/s, uses bare copper conductors and features gold-plated contacts. The exterior is halogen-free, flame-retardant and low-smoke (LSOH), and the cord is suitable for Power over Ethernet (PoE) applications.
Advantages
The S/FTP (S-STP) construction provides both pair-level foil shielding and an overall braided shield for improved noise immunity in high-speed networks. A small outer diameter (approximately 4.5 ± 0.2 mm) results in a slim, space-saving cable that is easy to route. Molded kink protection increases durability at the connector ends, and the 1:1 contact wiring conforms to the EIA/TIA 568 standard for reliable connectivity.
Suitable for
40 Gigabit Ethernet links in data centers and server rooms
High-speed backbone or switch-to-switch connections
Applications requiring Power over Ethernet (PoE)
Environments needing low-smoke, halogen-free cabling
Key specifications

Shielding: S/FTP (pair foil shield + overall braid)
Connector type: RJ-45 to RJ-45, straight male on both ends
Conductor: stranded bare copper, 8-wire
Contact plating: gold
Data transfer rate: up to 40 Gbit/s (40000 Mbit/s)
Outer diameter: approx. 4.5 ± 0.2 mm
Length: 0.3 m
Color: green
Flame retardant, halogen-free, low-smoke (LSOH)
How to use
Connect the RJ-45 plug on one end of the patch cord to the network port of a switch, router or server and the other RJ-45 plug to the corresponding port on the opposite device. Ensure connectors are fully inserted until they click to establish a secure 1:1 EIA/TIA 568 wiring connection. For optimal performance, avoid excessive bending at the cable ends and maintain proper cable routing to minimize interference.
Usage recommendations
Use this slim Cat8.1 S/FTP patch cord for short high-speed links (for example switch-to-switch or switch-to-server) within racks or between adjacent network equipment. Avoid installing it in long permanent horizontal runs where structured cabling standards require permanent-rated bulk cabling.
