Network cable LANBERG Cat8.1 S/FTP (S‑STP) RJ-45–RJ-45 Grey 3 m

LANBERG Cat8.1 S/FTP (S‑STP) RJ-45–RJ-45 Grey 3 m is a high-performance patch cable engineered for demanding network environments. With a 3 m length and robust S/FTP shielding (braid plus foil on each pair), this cable supports very high data rates while reducing electromagnetic interference. Fitted with RJ-45 connectors on both ends and built from 26 AWG conductors, it is suitable for short-range connections in data centers, server rooms, workstations and high-bandwidth home or office setups.

Advantages

The S/FTP shielding construction improves immunity to crosstalk and external EMI, ensuring more stable links in congested electromagnetic environments. Cat8.1 specification enables support for multi-gigabit and 40 Gbit/s class applications over short distances, while the compact 6.0 mm outer diameter keeps cable management tidy. RJ-45 termination provides broad compatibility with standard networking equipment without requiring specialized connectors.

Suitable for

• Short-run high-speed links in data centers and server racks
• Connections between switches, routers and patch panels
• High-bandwidth workstation or home office network segments
• Environments with elevated electromagnetic interference where shielded cabling is preferred

Key specifications

• Cable category: Cat8.1
• Shielding: S/FTP (overall braid + foil per pair)
• Connectors: RJ-45 – RJ-45
• Length: 3 m
• Conductor size: 26 AWG (7 x 0.16 mm)
• Outer diameter: 6.0 mm ± 0.2 mm
• Color: Grey
• Maximum supported data rate: up to 40 000 Mbit/s (over appropriate channel distance)

How to use

Connect the RJ-45 plug at one end of the LANBERG Cat8.1 cable to the network port of your switch, router, server or network interface, and the other RJ-45 plug to the corresponding device or patch panel. Ensure connectors are fully seated until the latch clicks. For best performance, avoid tight bends near the connectors and route the cable away from strong sources of electrical noise where possible.

Recommendations

Use this Cat8.1 S/FTP cable for short-distance, high-throughput links—typical in data centers and server rooms—and pair it with compatible shielded network equipment and properly grounded infrastructure to realize the full benefits of shielding. For longer runs, consider appropriate channel planning or alternative cabling to maintain signal integrity.
