Networking cable EFB Elektronik EC020200245 RJ-45 Cat8.1 0.5 m Yellow

The EFB Elektronik EC020200245 RJ-45 Cat8.1 0.5 m Yellow networking cable is a short, high-performance patch cable designed for demanding Ethernet connections. Compliant with the Cat8.1 standard, this cable supports very high data rates and is intended for short-distance links in data centers, server racks, and professional network installations. The S/FTP shielding and gold-plated RJ-45 connectors provide stable signal transmission and reduced electromagnetic interference in congested cabling environments.

Advantages

This Cat8.1 cable delivers data transfer rates up to 40000 Mbit/s over supported links while maintaining signal integrity through individual pair foil shielding and an overall braid. The gold-plated RJ-45 plugs ensure low contact resistance and improved durability for frequent insertions. Its compact 0.5 m length minimizes excess slack, which helps maintain tidy, organized racks and reduces crosstalk between adjacent cables. The yellow jacket improves visibility for quick identification in complex cabling setups.

Suitable for

• Short patch connections between switches, servers, and network appliances
• High-density rack environments and data center top-of-rack links
• Professional Ethernet installations requiring shielded cabling
• Situations requiring clear cable identification through colored jackets

Key specifications

• Category: Cat8.1 high-performance Ethernet cable
• Length: 0.5 m
• Connector type: RJ-45 to RJ-45
• Shielding: S/FTP (individual pair foil + overall braid)
• Max data rate: up to 40000 Mbit/s (depending on connected equipment)
• Colour: Yellow

How to use

Connect one gold-plated RJ-45 plug to the Ethernet port of a switch, router, patch panel or network device and the other plug to the corresponding port of the connected device. Ensure connectors are fully inserted until the latch clicks. Use this 0.5 m cable for short, direct links where minimal cable length is desired to reduce clutter and maintain neat cabling runs. For best performance, pair with compatible Cat8-capable hardware and maintain proper cable routing to avoid sharp bends or excessive mechanical stress.

Usage recommendations

Use the cable in shielded network environments and avoid running it in parallel with high-voltage power lines to minimize interference. Inspect connectors periodically for contamination and ensure secure terminations; replace the cable if visible damage to the jacket or connectors occurs. Choose colored cables like yellow to simplify network mapping and maintenance in dense installations.
