## Long description

The EFB Elektronik K4137GR.25 RJ-45 Cat6a 25 m Grey is a shielded network cable engineered for high-speed wired connections. Designed to support data transfer rates up to 10000 Mbit/s, this 25-metre Cat6a cable provides a reliable physical link between switches, routers, servers and workstations. The cable uses S/FTP shielding to reduce electromagnetic and crosstalk interference, while nickel- and gold-plated RJ-45 connectors ensure consistent contact quality and corrosion resistance. The neutral grey jacket facilitates discreet installation in office and data center environments.
Advantages
S/FTP shielding around individual pairs and an overall foil helps maintain signal integrity in environments with multiple adjacent cables and electronic equipment. Cat6a specification supports higher bandwidth and improved alien crosstalk performance compared with lower category cables. The combination of nickel and gold plating on RJ-45 plugs provides durable mechanical strength and stable electrical contact. A 25 m length covers medium to large cable runs without the need for intermediate patch points, simplifying wiring layouts.
Suitable for
10 Gigabit Ethernet connections in small offices and server rooms
Connecting switches, patch panels and network devices across floors or rooms
Wired workstations requiring low-latency, high-bandwidth links
Environments with significant electromagnetic interference where shielded cable is recommended
Key specifications
Cable category: Cat6a
Length: 25 m
Connector type: RJ-45 to RJ-45
Shielding: S/FTP (overall foil with individually shielded pairs)
Maximum supported data rate: up to 10000 Mbit/s
Conductor arrangement: twisted pairs
Jacket colour: Grey
How to use
Route the cable between network devices avoiding sharp bends and excessive tension. Terminate both ends into compatible RJ-45 ports, ensuring connectors are fully inserted and latched. For installations near sources of strong electromagnetic interference, orient the cable to minimize parallel runs alongside power lines and maintain distance where possible. If additional length or routing around obstacles is needed, use appropriate cable management such as cable trays or tie points to prevent strain on the connectors.
Usage recommendations
For optimal performance keep bend radius above four times the cable diameter, avoid kinking, and do not exceed the specified 25 m run for a single link without a network device in between. Use shielded connectors and properly grounded patch panels when deploying S/FTP cable to ensure the shielding performs effectively.
