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) applications. The outer diameter is approximately 4.5 mm and the cable length is 0.3 m.

Advantages

The double-shielded construction with pair foil-shielding and overall braided shielding reduces electromagnetic interference, while gold-plated contacts ensure reliable signal transmission. Molded kink protection increases durability and the slim design simplifies routing in dense installations. Bare copper conductors provide stable electrical performance and the cable complies with EIA/TIA 568 contact assignments (1:1).

Suitable for

40 Gigabit Ethernet connections in data centers and server racks
High-speed short patch connections between switches and routers
PoE-powered devices where compact, shielded cabling is required

Key specifications

Cable category: Cat8.1 (Class I)
Shielding: S/FTP (pair foil shielding with overall braid)
Connector type: RJ-45 to RJ-45, straight male
Data transfer rate: up to 40 Gbit/s (40000 Mbit/s)
Conductor material: bare copper, stranded (8-wire)
Contact plating: gold-plated contacts
Contact assignment: 1:1 (EIA/TIA 568)
Outer diameter: approx. 4.5 ± 0.2 mm
Fire performance: halogen-free, flame-retardant, low-smoke (LSOH)
Length: 0.3 m
Colour: black

How to use

Connect one RJ-45 plug to a network device such as a switch or router and the other plug to the corresponding port on the target device. Ensure both connectors are fully inserted and latched. Use this short, shielded patch cord for high-speed interconnects where minimal signal loss and reduced interference are required. No additional configuration is needed for PoE; power negotiation is handled by the connected devices.

Usage recommendations

For optimal performance, use the cable for short-distance, high-speed links within rack or cabinet environments and avoid tight bends at the connector area despite the molded kink protection. Keep shield terminations intact and ensure grounded equipment to benefit from the shielding.
