Networking cable M-Cab EC020200305 RJ-45 Cat8.1 5 m Black

The M-Cab EC020200305 RJ-45 Cat8.1 5 m Black networking cable is a high-performance copper patch cable designed for demanding data networks. Compliant with the Cat8.1 specification, it supports multi-gigabit and high-frequency applications and delivers rated data throughput up to 40000 Mbit/s over short runs. The cable uses shielded S/FTP (also referred to as S-STP) construction to reduce crosstalk and external electromagnetic interference, and it is fitted with gold-plated RJ-45 connectors for reliable contact and reduced corrosion. Its 5 meter length and black jacket make it suitable for structured cabling, server racks and desktop connections where a balance of performance and neat appearance is required.

Advantages

The wiring and S/FTP shielding provide improved noise immunity compared with unshielded alternatives, supporting stable high-speed transfers in crowded electromagnetic environments. Gold-plated RJ-45 plugs ensure consistent electrical contact and long-term durability. Compliance with Cat8.1 frequency and performance parameters enables use in data centers, backbone segments and short-distance high-bandwidth links. The 5 m length offers flexibility for installation between network equipment without excess slack.

Suitable for

• High-speed LAN connections between switches, servers and workstations
• Short-range backbone links in data centers and telecom rooms
• Applications requiring reduced interference, such as near power supplies or dense cable trays
• Desktop and rack-mounted network equipment with RJ-45 ports

Key specifications

• Category: Cat8.1 performance class
• Maximum data rate: up to 40000 Mbit/s (application dependent)
• Shielding: S/FTP (overall braid with individually shielded twisted pairs)
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Length: 5 m
• Jacket colour: Black

How to use

Connect one end of the cable to the RJ-45 port of your network device and the other end to the corresponding port on the switch, router or server. Ensure both devices are powered off or that hot-plugging is supported by your equipment before connecting. Route the cable to avoid sharp bends and excessive tension; maintain bend radii recommended for shielded Ethernet cables and avoid running parallel to high-voltage power lines to minimize interference. For rack installations, secure the cable with cable management accessories to prevent strain on the connectors.

Usage recommendations

The cable is optimized for short-run, high-bandwidth links; for distances beyond standard copper Ethernet limits consider fibre solutions. When installing in environments with high EMI, ensure proper grounding and continuity of shield connections at patch panels and equipment to retain shielding effectiveness.
