Networking cable EFB Elektronik K5525FRT.7,5 Cat6a S/FTP (S-STP) RJ-45 to RJ-45 Red 7.5 m

EFB Elektronik K5525FRT.7,5 is a Cat6a S/FTP (S-STP) patch cable in red with gold-plated RJ-45 connectors and a flexible TPE jacket. At 7.5 m length it is designed for 10 Gbit/s class Ethernet links and structured cabling where enhanced shielding and interference protection are required. The cable’s S/FTP construction combines an overall foil with individual pair shielding to reduce crosstalk and EMI, making it suitable for installations in server rooms, network racks and point-to-point connections between switches and managed devices.

Advantages

The cable provides Cat6a performance up to 10 000 Mbit/s and is built with S/FTP (S-STP) shielding to limit electromagnetic interference. Gold-plated RJ-45 plugs ensure reliable contact and corrosion resistance, while the TPE outer jacket offers increased flexibility for routing in confined spaces. The red colour improves visual identification in structured cabling environments.

Suitable for

• 10 GbE connections between switches, servers and NAS devices
• Structured cabling in data centres and server rooms
• High-density rack installations where shielded cables are required
• Point-to-point Ethernet links and workstation connections needing EMI protection

When it may not be suitable

This cable may be unnecessary for simple home networks or applications that operate well under Cat5e/Cat6 performance, where the extra shielding and Cat6a specification do not provide measurable benefits. It is not intended for permanent outdoor burial or direct exposure to harsh environmental conditions unless protected by appropriate conduit or tray systems.

Key specifications

• Cable category: Cat6a
• Shielding: S/FTP (overall foil plus individually shielded pairs)
• Connectors: RJ-45 to RJ-45 with gold-plated contacts
• Length: 7.5 m
• Jacket material: flexible TPE
• Maximum supported data rate: up to 10 000 Mbit/s (10 Gb/s)
• Colour: red

How to use

Connect one RJ-45 plug to the network port of a switch, router or server and the other plug to the target device. Ensure that connected equipment supports Cat6a or 10 GbE where higher speeds are required. Route the cable avoiding sharp bends and sources of strong electromagnetic interference where possible; secure with cable management accessories to maintain performance and prevent strain on the connectors.

What to consider before purchase

• Verify the required cable length and whether 7.5 m fits the intended routing.
• Confirm that your equipment benefits from Cat6a/10 GbE capability.
• Check whether shielded cabling is necessary in your environment to reduce EMI.
• Decide if the red jacket colour fits your cable identification scheme.

Usage recommendations

For optimal performance, use this Cat6a S/FTP cable within structured cabling standards: avoid kinking, maintain minimum bend radius recommended by installers, and pair shielded cables with grounded shielded connectors or patch panels when required by your installation.
