Networking cable EFB Elektronik K5545WS.0,25 Cat6a U/FTP (STP) 0.25 m RJ-45 to RJ-45 White

Shielded patch cable EFB Elektronik K5545WS.0,25 is a short Cat6a connection cable designed for high-speed Ethernet links. The cable is 0.25 m long and uses U/FTP (overall unshielded braid with individually foil‑shielded pairs) structure to reduce electromagnetic interference and crosstalk in dense rack or workstation environments. Both ends are terminated with RJ-45 plugs with gold‑plated contacts, supporting data rates up to 10 000 Mbit/s and ensuring reliable signaling for 10 Gigabit Ethernet over short runs.

Advantages

The U/FTP (STP) shielding provides improved protection against external interference compared with unshielded cables, making it suitable for installations near power sources or other cabling bundles. Gold‑plated contacts on the RJ-45 connectors help maintain low contact resistance and reliable long‑term conductivity. The short 0.25 m length reduces cable clutter in patch panels and switch stacks, contributing to cleaner rack management and minimal signal attenuation over the intended short distance.

Suitable for

• Patch connections between switches and patch panels in data cabinets
• Short links from switch ports to server NICs or storage appliances
• Workstation or desk-side connections where shielded Ethernet is required
• High-density network racks where cable routing and interference control are important

How to use

Insert each RJ-45 plug into the corresponding port on the devices to be connected, ensuring a firm click for proper engagement. Use the cable for short point-to-point connections inside racks, between patch panels and switches, or between switches and servers. Maintain proper grounding when integrating shielded cables into a rack or patch panel system to preserve the shielding effectiveness. Avoid sharp bends near the connectors and do not exceed the intended bend radius to prevent mechanical damage.

Usage recommendations

For optimal performance, route the shielded cable alongside other shielded infrastructure and ensure consistent grounding of chassis and panels. Choose the 0.25 m length when you need a tidy connection with minimal excess cabling in high-density rack environments.
