Product information

Description

ROLINE 21.15.3423 is a slim, double-shielded Category 8.1 (Class I) patch cord with screened RJ-45 connectors on both ends. Designed for high-speed networks, it supports data rates up to 40 Gbit/s and is suitable for Power over Ethernet (PoE). The cable uses bare copper conductors, gold-plated contacts and a compact outer diameter for space-saving routing while the sheath is halogen-free, flame-retardant and low-smoke (LSOH).

Advantages

The construction combines pair foil-shielding with an overall braided shield (S/FTP) to minimise electromagnetic interference and crosstalk. A slim outer diameter of approximately 4.5 ± 0.2 mm reduces cable bulk while molded kink protection increases connector durability. Gold-plated contacts ensure reliable signal transmission and compatibility with 40 Gigabit Ethernet installations.

Suitable for

Data centres and server racks requiring 40 Gbit/s links
High-speed LAN backbones and switch-to-switch connections
Environments where PoE devices are used (phones, access points, cameras)
Installations needing low-smoke, halogen-free cabling

Key specifications

Cable standard: Category 8.1 (Class I)
Shielding: S/FTP (individual foil for pairs + overall braid)
Connector type: RJ-45 straight male — both ends
Conductor: 8-wire stranded cable with bare copper conductors
Contact plating: Gold-plated contacts
Maximum data rate: 40 Gbit/s (40000 Mbit/s)
Outer diameter: approx. 4.5 ± 0.2 mm
Cable length: 3 m
PoE support: compatible with Power over Ethernet
Sheath: halogen-free, flame-retardant, low-smoke (LSOH)
Contact assignment: 1:1 according to EIA/TIA 568

How to use

Connect the RJ-45 straight male plugs into the corresponding RJ-45 ports of network devices such as switches, routers or servers. Ensure connectors are fully inserted until the latch clicks for a secure connection. Route the slim cable to avoid sharp bends and mechanical strain; the moulded kink protection reduces stress at the connector but standard cable management practices should be followed.

Usage recommendations

For optimal performance in 40 Gigabit Ethernet links, use the ROLINE Cat8.1 patch cord for short horizontal or rack-to-rack connections within data centres and enterprise networks, keep cable runs within recommended lengths for channel specifications, and avoid running the cable parallel to high-power electrical lines to minimise interference.
