Product information

Description

EFB Elektronik K5528GR.7.5 is a 7.5 m Cat8.1 networking patch cable with RJ‑45 connectors on both ends. Engineered for 40GBase‑T cabling, the S/FTP (S‑STP) shielding construction reduces crosstalk and electromagnetic interference to support data rates up to 40,000 Mbit/s. The grey cable is intended for high‑speed Ethernet links in data centres, server rooms and professional network installations where short, high‑capacity connections are required.

Advantages

The S/FTP (S‑STP) shielding provides individual foil around each pair plus an overall braid to minimise pair‑to‑pair crosstalk and external EMI, improving signal integrity for demanding 40GBase‑T applications. With RJ‑45 terminations on both ends and a 7.5 m length, the cable offers a ready‑to‑use solution for patching between switches, patch panels and servers. The Cat8.1 specification supports very high bandwidth and is backward compatible with lower Ethernet categories when needed.

Suitable for

Short high‑speed links in data centres and server rooms
Patching between switches, servers and patch panels
Professional network installations requiring 40GBase‑T performance
Environments where reduced electromagnetic interference is required

When it may not be suitable

This Cat8.1 patch cable is designed primarily for short‑reach, high‑bandwidth applications; it is not intended for long horizontal cabling runs in structured cabling installations. If you need outdoor, plenum‑rated or specially armoured cable for harsh environments, this standard patch cable may not meet those specific physical or regulatory requirements.

Key specifications

Cable length: 7.5 m
Cabling class: Cat8.1
Shielding: S/FTP (individual pair foil + overall braid)
Connectors: RJ‑45 to RJ‑45
Supported technology: 40GBase‑T
Maximum data rate: up to 40,000 Mbit/s
Colour: Grey

How to use

Connect the RJ‑45 plugs to the appropriate ports on networking equipment such as switches, patch panels or servers. Ensure both endpoints support the required 40GBase‑T performance if you intend to operate at the highest data rates. Route the cable to avoid tight bends and sources of strong electromagnetic interference; keep slack for rack management and strain relief. The cable is plug‑and‑play and requires no configuration.

What to consider before purchase

Intended cable length and rack/panel distances to ensure 7.5 m is sufficient
Required category and performance level (Cat8.1 and 40GBase‑T compatibility)
Environmental and installation conditions (indoor use, not specialised outdoor/plenum rated)
Connector compatibility with existing RJ‑45 ports

Usage recommendations

For optimal performance, use this Cat8.1 S/FTP patch cable for short, direct connections between high‑speed devices in controlled indoor environments, keep bend radius within manufacturer guidelines, and avoid running parallel to high‑power cabling to minimise EMI.
