Product information

Description

High-quality, slim Category 8.1 (Class I) patch cord with double shielding and screened RJ-45 connectors on both ends. The cable supports data rates up to 40 Gbit/s, is halogen-free, flame-retardant and low-smoke (LSOH), and is suitable for Power over Ethernet (PoE). The outer cable diameter is approximately 4.5 ± 0.2 mm and the length is 3 m.

Advantages

Double shielding (foil on pairs plus overall braid) and gold-plated contacts ensure reliable high-speed signal transmission and reduced interference. The slim construction and molded kink protection provide flexibility and easy routing in crowded installations. LSOH properties and flame-retardant materials reduce toxic emissions and fire risk, while compatibility with PoE allows power delivery over the same cable.

Suitable for

40 Gigabit Ethernet backbone and switch-to-switch connections
High-density server racks and data centre horizontal cabling
Environments requiring PoE devices with high bandwidth demands
Installations where low-smoke, halogen-free cabling is required

Key specifications

Cable standard: Category 8.1 (Class I)
Shielding: S/FTP (individual foil on pairs + overall braided shield)
Connector type: RJ-45 plug — straight on both ends
Conductor: bare copper, stranded, 8-wire
Contact plating: gold
Data rate: up to 40 Gbit/s (40000 Mbit/s)
Power over Ethernet (PoE) compatible
Outer diameter: approx. 4.5 ± 0.2 mm
Length: 3 m
Colour: black

How to use

Connect each RJ-45 plug to the corresponding RJ-45 ports on network devices such as switches, routers or servers. Ensure connectors are fully inserted until the latch clicks. Route the cable avoiding sharp bends; the molded kink protection helps prevent damage at the connector. For installations in racks or conduits, verify bend radius and secure the cable to avoid strain on terminations.

Usage recommendations

Use this Cat8.1 S/FTP patch cord for short runs between high-speed equipment within the same rack or between adjacent racks. Keep cable length within specified limits for optimal 40 Gbit/s performance and avoid running alongside large power cables to minimize electromagnetic interference.
